Support roller (yoke-type track roller), without flange rings, with integral sealing
Support rollers (yoke-type track rollers) are designed to run on all types of tracks and to be used in cam drives, conveyor systems, etc.
They are based on a single row needle roller bearing with an inner ring and have a thick-walled outer ring with a crowned running surface. They are supplied sealed and are ready-to-mount. The inner ring contains a lubrication hole to facilitate relubrication. The inner ring can be mounted separately from the outer ring and roller and cage assembly.
- High radial load carrying capacity
- Able to withstand shock loads
- Ready to mount
- Separable design
- Integral sealing prolongs bearing service life
