Support rollers are a special design of cylindrical roller bearings. They have a reinforced outer ring. In contrast to rolling bearings support rollers are not incorporated into a casing but rather run with their outer ring on a straight or curved guide rail.

The load-bearing quality depends not only on the rolling element but also on the strength of the outer ring. This is taken into account in the material choice and the heat treatment.

Besides the high strength a good seal against dirt entering from the outside and loss of grease from inside the bearing is very important for durability.

METER produces support rollers with diameters of up to 500 mm. Cylindrical roller bearings, angular ball bearings or four point bearing are the most common designs.

Mast rollers are a special design of support rollers, conceived specifically for use in fork lift trucks. Mast rollers support the mast and the fork arm carriage on the fork lift truck.

They are highly loaded and transfer very large loads in radial and axial directions at low speeds. They also absorb moment load via the outer ring.

High shock loads require a balanced concept with regard to the bearing assembly and outer ring wall strength. Materials and heat treatment of the rings are designed specifically for these requirements.

Besides the high strength a good seal against dirt entering from the outside and loss of grease from inside the bearing is very important for durability.

METER manufactures mast rollers with diameters of up to 300 mm. Cylindrical roller bearings, angular ball bearings or four point bearing are the most common designs.

Chain rollers are a special design of support rollers, conceived specifically for use in fork lift trucks. Chain rollers redirect the lifting chain on the fork lift truck and are usually mounted directly on the lifting cylinder. They are highly loaded and transfer very large loads in radial directions at low speeds.

High shock loads require a balanced concept with regard to the bearing assembly and outer ring wall strength. Materials and heat treatment of the rings are designed specifically for these requirements.

METER manufactures chain rollers with a diameter of up to 300 mm. Cylindrical roller bearings or angular ball bearings are the most common designs.

Cylindrical roller bearings are radial bearing that can support high loads and have a solid inner and outer ring. The roller bearings are cylindrical. Cylindrical roller bearings are very rigid and can support high loads. The individual designs differ in their edge arrangement, i.e. as fixed bearings, support bearings or floating bearings. Some designs have cages that are suitable for high speeds and full roller designs that are used for high radial loads and slow rotary movements.

METER manufactures cylindrical roller bearings with diameters of up to 1000 mm, either with or without cage. The following designs are available:

Cylindrical roller bearings with cage

NU – Floating bearings with 2 edges on outer ring
N – Floating bearings with 2 edges on inner ring
NJ – Support bearings with 2 edges on outer ring and one edge on inner ring
NUP - Fixed bearings with support disk on inner ring
NJ+HJ – Fixed bearings with support ring on inner ring
NN – as multiple row design with cage

Full roller cylindrical roller bearings

Full roller cylindrical roller bearings are available on demand in single row or multi-row designs as floating, fixed or support bearings.

Planetary gear bearings are multi-row, high load cylindrical roller bearings without an outer ring. They are special bearings that are designed specifically for each application.

Planetary gear bearings support the planetary gear in the planetary gearbox. Here the bearings transfer the high loads from the gearing geometry between the sun gear and the ring gear. The corresponding planetary gears, which also form the outer ring of the bearings, are usually produced by the customer.

METER manufactures planetary gear bearings in with diameters or up to 500 mm on demand, either with or without outer ring. Designs are possible with inner ring for mounting on the shaft or with pivots. The bearings are packed and delivered with the roller bearing assembly.

Rotary connections are high load moment bearings with mounting holes on the inner and outer ring. They are special bearings that are designed specifically for high moment loads at low speeds.
 
Rotary connections serve to support swivel drives, round tables or drive gears in a fork lift truck. Here the bearings transfer the high axial loads and torque as a single bearing.

Rotary connections often only carry out swivel moments with small rotation angles and speeds. The inner and outer ring are designed as a flange with threads or drilled holes for mounting purposes.
 
Angular ball bearings, four point bearings or cross roller bearings are possible designs.
 
METER manufactures rotary connections with diameters of up to 1000 mm, either with or without gearing. Larger dimensions are possible on demand through cooperation with partner businesses.

Anything is possible! Away from the well-beaten rolling bearings track bearings solutions exist that you cannot yet imagine today but which could be essential for your application in the future. Whether because of high power density in small dimensions or special geometry that fits your bearing location like a glove.

Problems with conventional bearing seals? Special dimensions that don’t follow any norm? METER will stand by you for this kind of query. Our engineers can support you with advice, calculations and designs for your individual bearing location. Our flexible range of machinery can allow economic solutions for even small quantities of bearings that differ from the standard designs. And all this in diameters from 10 to 1000 mm.
