Family specifications and selection conditions
| Product description | Insert bearings are based on sealed deep groove ball bearings. This variant is suitable for applications with both constant and alternating directions of rotation. It has an inner ring extended on both sides and is locked onto the shaft by tightening two (set) screws on the inner ring, making it easy to mount. |
|---|---|
| Manufacturer features | Designed for a constant and alternating rotation • Quick and easy to mount onto the shaft • Reduce noise and vibration levels |
