Square flanged housing for insert bearings, cast iron
These square flanged housings for insert bearings are made of grey cast iron and can be bolted with four bolts to a machine wall or frame.
They have been developed for bearing arrangements that must operate reliably in difficult environments.
- Resist high levels of contamination
- Accommodate relatively heavy loads
