Family specifications and selection conditions
| Product description | Take-up ball bearing units, consisting of an insert bearing based on a sealed deep groove ball bearing mounted in a grey cast iron housing. This variant is intended for use in applications where the direction of rotation is constant. It has an inner ring extended on one side, with an eccentric locking collar, enabling quick and easy mounting onto the shaft. |
|---|---|
| Manufacturer features | Designed for rotation in one direction • Quick and easy to mount onto the shaft • Accommodate static initial misalignment • Long service life • Reduced noise and vibration levels |
