IBC Radial Ball Bearings are suitable for a wide variety of applications. They are suitable for high-speed applications due to low friction and are insensitive in case of operation and maintenance.
The ability to carry radial as well as axial loads, they are the most commonly used bearing type. IBC Radial Ball Bearings can be supplied in a large number of sizes and designs, different cross sections covering a wide variety of applications.
IBC Radial Ball Bearings are available as both side open basic design and with seals or shields at one or both sides.
Bearings with shields or seals at both sides can be filled with different kinds and quantities of grease for individual requirements.
Due to their low friction features, the possibility of high precision production and their silent running ability Deep Groove Ball Bearings are often used in small and medium electric motors.
IBC Radial Ball Bearings can be supplied as matched pairs on request. As standard they are mainly produced with phenolic cages (TB) supplied with a defined axial bearing clearance in back-to-back-arrangement (DB). One-side shields or seals are possible. Further variations are available on request.
IBC Radial Ball Bearings could also be produced with various cage and ball materials as well as with ATCoat surface coated rings.
Thin section bearings of series 618.. and 619.. with small cross section are often used for designs that are extremely light and require little space.
Apart from to the above mentioned standard bearings, IBC produces further Deep Groove Ball Bearings in high precision quality.

Angular Contact Ball Bearings have raceways in the inner and outer ring, which are displaced with respect to each other in the direction of the bearing axis. This means that they are suitable for acting radial and axial loads. The axial load carrying capacity of Angular Contact Ball Bearings increases with increasing contact angle.
Single Row Angular Contact Ball Bearings can support radial and thrust loads. They accommodate thrust loads in only one direction; they are adjusted against another bearing, which support the opposite axial load. Single Row Angular Contact Ball Bearings of series 70 BEP, 72 BEP and 73 BEP have a contact angle of 40°. They can therefore accommodate high axial loads, are non-separable and are suitable for particularly high speed.
The Single Row Angular Contact Ball Bearings are produced in two standard versions for different purposes. The standard design is intended for arrangements where only one bearing is used at each bearing position.
Universal preload ground bearings are intended for being mounted in pairs either in X- O- or Tandem-arrangement or for other group mounting. They could be mounted in any possible arrangement.

The following adjustments can be selected:

• UA small axial clearance at X-or O-arrangements
• UO zero clearance at X- or O- arrangements
• UL light clearance
   

These bearings are specially manufactured so that when mounted in random order, but immediately adjacent to each other, the predetermined value of axial internal clearance or preload will be attained, or an even distribution of load, without shims or similar devices having to be used.
When arranged in tandem the load lines are in parallel and the radial and axial loads are evenly divided between the bearings. The bearing pair is only able to accommodate axial loads in one direction so that a third bearing is generally adjusted against the pair to carry the axial loads acting in the opposite direction.
The load lines of bearings in O-arrangement diverge towards the bearing axis. Axial loads acting in both directions can be accommodated, but only by one bearing in each direction. Bearings mounted in O-arrangement provide a relatively stiff arrangement, which can also accommodate tilting moments.
Regarding load lines of bearings in X-arrangement, axial loads acting in both directions can be carried, but only by one bearing in each direction. This arrangement is not stiff as the O-arrangement and is also less suitable for the accommodation of tilting moments.
Most Angular Contact Ball Bearings are fitted with a one-piece polyamide cage. Steel and brass cages are available as standard. Other materials are available on demand.
The design of Double Row Angular Contact Ball Bearings corresponds to a pair of Single Row Angular Contact Ball Bearings in O-arrangement. The bearings can accommodate high radial loads and thrust loads in both directions. The basic designs of Double Row Angular Contact Ball Bearings have a 32° contact angle. Bearings of series 32 and 33 are manufactured as open bearings but also with seals or shields on both sides. Basic Double Row Angular Contact Ball Bearings have normal tolerances.
Double Row Angular Contact Ball Bearings are fitted with cage of glass-fibre-reinforced polyamide or with steel cage.
High Precision Angular Contact Ball Bearings are a further version such as Spindle Bearings for machine tools with 15° and 25° contact angle as well as 60° Angular Contact Ball Bearings for ball screws.

IBC Self-Aligning Ball Bearings are of double row type, with a spherical outer ring raceway. The inner ring has two grooves similar to these of Deep Groove Ball Bearings. Their self-aligning capability allows them to compensate for misalignments. Self Aligning Ball Bearings are designed for medium up to high rotational speeds and can accommodate radial and axial loads in both directions.
They are available with cylindrical or tapered bore. Bearings can be fixed on the shaft via adapter sleeve.
Generally the series 12, 22, 13, 23 are available.
Depending on application, IBC Self Aligning Ball Bearings are fitted with a polyamide cage or in case of special units even with solid brass cages.
In addition to unsealed IBC Self Aligning Ball Bearings of series 22.. and 23.., a basic design with seals on both sides can be supplied.
It should be observed that the inner design of the bearings correspond to the series 12.. and 13...

Single direction Thrust Ball Bearings comprise shaft locating washers, housing locating washers as well as ball and cage assemblies. They can only support axial forces but must not be subjected to radial loads. They can be dismantled, that allows separate mounting of shaft, cage and housing. Due to centrifugal force, balls try to leave the raceway; therefore a minimum axial load is always required.
Generally the series 511, 512, 513 are available. IBC Thrust Ball Bearings are available with normal tolerances PN, as well as high precision P5, P4 according to DIN 620, part 3.

IBC product range is presenting various and innovative solutions guaranteeing safe bearing functions.
Further to the already mentioned bearing variations, Cylindrical Roller Bearings are produced in single row version with cage. They consist of one-piece inner and outer ring as well as cylindrical roller crown. The cage avoids contact of rolling elements against each other The roller set is designed for maximum load carrying capacity in radial direction. The line contact between rolling elements and raceway enables high rigidity. They cannot carry axial loads and are used as floating bearings.
Single Row Cylindrical Roller Bearings are separable. This facilitates mounting and dismounting. Cylindrical Roller Bearings are produced in different designs depending on various requirements. The various designs are distinguished in the following basic designs. Type NU Cylindrical Roller Bearings have two tight ribs at the outer ring, whereas there is no rib at the inner ring. Type N has two tight ribs at the inner ring and an outer ring without rib. They can carry free and easy axial load between shaft and housing in both directions and therefore are only used as floating bearing. With different inner and outer rings they are available in design NJ, NUP, NF, NP in series 10, 2, 3, 22 and 23. These series are produced as standard in design E with reinforced roller set.
Design NJ has two fixed ribs at the outer ring and one fixed rib at the inner ring, so that axial location can be provided for the shaft in one direction. Further to the standard Cylindrical Roller Bearings, IBC is also producing High Precision Cylindrical Roller Bearings.
Cylindrical Roller Bearings of type NUP have two fixed ribs at the outer ring and a fixed rib at the inner ring, as well as loose shoulders. They are used as locating bearings as they are leading the shaft in both axial directions.
Cylindrical Roller Bearings with suffix E with reinforced roller cage assembly are designed for maximum load carrying capacity, at unchanged outside dimensions.
Cylindrical Roller Bearings of version E are produced with a reinforced Polyamide 6.6 cage. Solid brass cages, rib or rolling element guided are standard versions too. Lots of dimensions are available with steel cage.
ATCoated Cylindrical Roller Bearings are an alternative to avoid fretting corrosion and to guarantee slide fit.

IBC Full Complement Cylindrical Roller Bearings are ring guided Cylindrical Roller Bearings. They are suitable for particularly compact designs.
As these bearings have the largest possible number of rolling elements, they can meet extremely high radial load carrying capacity and high rigidity. They cannot achieve the high speeds that are possible when using cylindrical roller bearings with cage.
Depending on application ATCoat is recommended thus service lifetime can be increased.
Full Complete Cylindrical Roller Bearings are available in single and double row designs.

Cylindrical Roller Thrust Bearings have particularly small axial section width, high load carrying capacity and high rigidity. They can support axial forces in one direction. Cylindrical Roller Thrust Bearings are a combination of axial cylindrical roller cage assembly, shaft and housing locating washers.
Cylindrical Roller Thrust Bearings are often used for bearing arrangements when capacity load of Thrust Ball Bearings come against limiting factors.
Axial cylindrical roller cage assemblies consist of a cage as well as one or two rows of cylindrical rollers and have a small axial width. They are used as a combination of shaft and housing washers.

The rolling elements of Tapered Roller Bearings look like truncated cones.
The inner ring (cone) has a special back face rib at the large cone diameter for axial load purposes. The front face rib at the smaller cone diameter together with the cage avoids dropping out of rollers.
For easy mounting the outer ring (cup) has no shoulders.
IBC Tapered Roller Bearings are designed for high radial and unidirectional axial loads for medium rotational speed. Generally the series 30..A, 31..A, 32..A are available. Arrangement in pairs allows for axial load in both directions.
Due to contact angle Tapered Roller Bearings are intended for axial loads. Therefore a second bearing for counter guidance is necessary.

Spherical Roller Bearings are made for heavy-duty applications.
They feature two rows of symmetrical barrel rollers. There are two separated raceways within the inner ring. Both roller rows are positioned in a common spherical outer ring raceway and therefore shaft deflection and misalignments at the bearing seating are compensated.
They are designed for high radial and relatively high axial loads at medium rotational speed. Spherical Roller Bearings are made either with a cylindrical or with a tapered bore.
IBC Spherical Roller Bearings are available in series 222.., 223.., 230.., 232.., 239.., 240.., 241.. . and are made either with steel , or with brass cages.
Screen Bearings are a special version of Spherical Roller Bearings.

Needle Roller Bearings are roller bearings with cylindrical rollers, which are thin and long in relation to their diameter (needles). In spite of their low cross section, the bearings have a high load carrying capacity and are thus eminently suitable for bearing arrangements where radial space is limited.
Needle Roller Bearings are used with and without inner ring.
Needle Roller Bearings only permit axial movement between shaft and housing, within certain limits. They are designed for bearing applications when grinding or hardening of the shaft is not possible or economically reasonable. If grinding and hardening of shaft is possible Needle Roller Bearings without inner ring are used. Due to non-availability of inner ring, shaft can be designed stronger and more rigid.
One further version is the Needle Roller Assembly, which is used as rolling element without inner and outer ring.

IBC corrosion resistant bearings carry the prefix S (example: S 6000) and show corrosion resistance against air humidity.
They have similar running characteristics as bearings out of bearing steel, however their carrying capacity is lightly reduced. Corrosion resistant steel bearings are available open or with seals on both sides.
Depending on humidity concentration in air or even salinity concentration, ATCoat is recommendable.

Bearing arrangements have to be selected depending on individual application. Various factors like temperature, lubrication, rotational speed, load capacity, humidity, vibration, mounting, maintenance, etc. have to be taken into consideration. Special bearings with special features are used for special kinds of applications, for which these bearing arrangements are suitable. High performance bearings with a high degree of reliability guarantee a long service life and operational safety of the machines, plants and aggregates.
For all kinds of above-mentioned bearings such as Deep Groove Ball Bearings, Angular Contact Ball Bearings, Self Aligning Ball Bearings, Thrust Ball Bearings, Cylindrical Roller Bearings, Spherical Roller Bearings, Needle Roller Bearings IBC is manufacturing special bearings for customized designs referring to outer dimensions, or special inner designs and not only standardised in ISO series.

To come to a round-up of the IBC bearing programme and to support the user with information about the most suitable lubrication, IBC has increased the product range by bearing grease. Long service life and performance of bearings is depending on the right choice of the right lubricant. Lubricants also avoid corrosion and contamination.
The lubricant quantity needed for bearings is small. The primary task of the lubricant is the right viscosity, if possible no contamination, availability in all operation zones, all operation circumstances, at any time and any sufficient quantity.
Due to mechanical stress and chemical ageing the lubrication ability is reducing in the course of time. Therefore it is necessary to re-new or to replenish the contaminated lubricant from time to time.
