Pillow block ball bearing unit for insert bearing with narrow inner ring and eccentric locking collar, pressed steel housing
Pillow (plummer) block ball bearing units with pressed steel housing consisting of an insert bearing mounted in a pressed steel housing that can be bolted to a support surface. The unit components need to be ordered separately.
The pressed steel housings for insert bearings are lightweight and made from cold-rolled steel and are zinc-coated for corrosion protection. The bearing is intended for use in applications where the direction of rotation is constant.
- Lightweight
- Protection against corrosion
- Accommodate static initial misalignment
- Reduce noise and vibration levels
- Flexible bearing and housing combinations
