Family specifications and selection conditions
| Product description | Pillow (plummer) block ball bearing units consist of an insert bearing mounted in a cast iron housing that can be bolted to a support surface. This variant is intended for use in applications where the direction of rotation is constant. It has a narrow inner ring and is locked onto the shaft by an eccentric locking collar, making it easy to mount. |
|---|---|
| Manufacturer features | Strong • Ready to mount • Lubricated and sealed bearing • Designed for rotation in one direction • Accommodate static initial misalignment |
