SUPPORTO SKF PER ALTE TEMP. FYTB25 TF/VA201
Unità cuscinetto a sfere
Description
These oval flanged ball bearing units are designed for high temperature applications and are compliant with ISO standards. They consist of a high temperature insert bearing, with an extended inner ring and set screw locking, and are suitable for applications where the direction of rotation is constant or alternating. The bearing is mounted in a cast iron housing, which can be bolted to a machine wall or frame. Ball bearing units can accommodate moderate initial misalignment, but normally do not permit axial displacement.
- Resist high levels of contamination
- Designed for high temperatures applications
- Accommodate relatively heavy loads
- Cost-effective
