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. Typically mounted in take-up frames, the unit has an inner ring extended on both sides and is locked by tightening a set screw on the inner ring, which makes it easy to mount. |
|---|---|
| Manufacturer features | Designed for an alternating rotation • Quick and easy to mount onto the shaft • Accommodate static initial misalignment • Long service life • Reduced noise and vibration levels |
