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.

The DTB (Driven Tool Bearings) high precision bearing series has been specially designed for driven tools that carry out milling and drilling work in state-of-the-art high precision machine tools. This sort of work is typically performed in a confined installation space under conditions that include short cycle times and great  machining forces.

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 40° angular contact ball bearings only absorb axial
forces in the direction in which the rolling elements are loaded as
a result of pressure brought to bear between the high shoulders
of the inner and outer ring. Because of the contact angle, any
radial forces that take effect produce an axial force; the design
must therefore make allowances for this axial force elsewhere.

The customer benefits from these bearings because they are easy
to install, have a long service life without needing maintenance
and allow for the possibility of being provided with for life grease
lubrication or circulating oil lubrication. Additional benefits include
high positioning accuracy and low energy consumption during
operation; the bearings also operate safely during fast acceleration
and high rotational speeds of the ball screw.

The large contact angle of 60° allows for high thrust load with high stiffness. The radial load should not extend 90 % of the preload.
As angular contact bearings can carry load only in one direction they therefore have to be adjusted to another bearing of the same kind.The bearings are primarily supplied as single ones or in sets of 2 or 4 bearings to be mounted in back-to-back arrangements. Angular contact thrust bearings are manufactured for universal matching, thus they can be rearranged and can be mounted in any arrangement.

For a fast and easy installation procedure IBC recommends the use of precision bearing units that are ready for assembly. The main field of application for such bearing units is ball screws in machine tools; the units are lubricated for life and sealed with labyrinth seals. The many possible arrangements within a rolling bearing set (which are designed to meet the many different requirements the bearings have with regard to great axial stiffness and load rating, low friction, high running accuracy as well as high rotational speeds and fast acceleration) led us to develop a modular system that provides the design engineer with great flexibility when designing different versions.

IBC Precisions Locknuts with fine thread are used for high-precision application. Due to integrated safety systems in the various locknuts, an easy and precise mounting, as well as safeguarding of locknuts is guaranteed. Installation of lockwashers within an axial groove is no longer necessary. The material cross section is maintained and the notch effect is not increased. Additionally axial
precision is enhanced.

BC 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.

The guiding consists of a profile rail on the outer side in which a ball-guided rail runs. The balls roll in linear raceways, thus enabling movement of the inner profile within the outer profile and therefore an extraction. Both inner profiles as well as the outer profile are equipped with running grooves. The rolling elements assure a steady transmission of forces that is low in friction and has a high degree of stiffness. The profiles can be customized for clearance, zero backlash or for preload. As the track is integrated inside the profile rail, it is protected from dirt as well as from vibra-tion, therefore preserving easy running features. The compact design of IBC telescope linear motion bearings favour their application in narrow construction spaces.

An ATC thin dense chromium coating protects the surface from outside environmental conditions and thereby increases the service life of rolling bearings and the life time of machines and equipment. The advantages of this coating also include energy saving and an efficient use of material. The ATCoat process permits the combination of a tough basic material with a firmly adhering, very thin and accurate chromium coat that is free of cracks. This is why, compared to bearings of the same size, those with an ATCoat coating offer very good resistance to wear and corrosion.
