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 single row needle roller bearing with an inner ring. They have a thick-walled outer ring with a cylindrical running surface and are supplied ready-to-mount. The inner ring contains a lubrication hole to facilitate relubrication. The outer ring, the inner ring and the needle roller and cage assembly can be mounted separately. |
