Support rollers
C&H support rollers have an internal design based on needle or cylindrical roller bearings. They have a thick-walled outer ring, which enables them to accommodate high radial loads, while reducing distortion and bending stresses.
The outer ring running surface is crowned as standard. However, support rollers with a cylindrical (flat) running surface are also available. These pre-greased, ready-to-mount units are suitable for all types of cam drives, tracks and conveyor systems.

- The Yoke Type Track Roller NA22/6-2RSR belongs to the series with axial guidance and labyrinth seals on both sides
- it consists of a thick-walled outer ring with profiled outside surface profile and a needle roller and cage assembly, it is both side lip sealed and filled with grease
- since the bearing hasn´t got a cage, it has a particularly high load capacity by the maximum number of rolling elements and supports high radial and also high axial loads
- it has a temperature resistance ranging from -10 °C up to 120 °C
- the inner ring can be fixed - separately from the outer ring - with the needle roller and cage assembly
- it is used if the axis doesn´t have a hardened and ground raceway

The Yoke Type Track Roller PWTR15-2RS belongs to the series of full complement cylindrical roller set with axial guidance
- it is based on double row, full complement cylindrical roller bearings; the two rows of rollers are guided separately from each other by the three ribs firmly mounted on the outer ring; two loose rib washers serve as axial support
- it has a particularly high load capacity by the maximum number of rolling elements and supports high radial and also high axial loads In addition, there is a reduction of friction due to the open space between the roller sets which is filled with grease, relatively high and also permanent axial loads can thus be supported
- it has a temperature resistance ranging from -10 °C up to 120 °C
- the axial guidance of the roller sets is carried out by two ribs firmly fixed on the outer ring
- use of these bearings as pressure rollers, cam followers, conveyor belt rollers, bearings for fork lift masts
- example application: packaging machines, transport systems, roll-up doors, roller tensioners, fork lift
