Family specifications and selection conditions
| Product description | 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 double row full complement cylindrical roller bearing with an inner ring and have a thick-walled outer ring with an improved crowned running surface. They are supplied sealed and ready-to-mount. The inner ring contains a lubrication hole to facilitate relubrication. |
|---|---|
| Manufacturer features | High radial load carrying capacity • Accommodate relatively heavy axial loads due to skew or tilting • Long service life • Ready to mount • Sealed for increased reliability, with relubrication feature |
