Key Features:
- Self-alignment capability
- Enables free rotation of the inner ring, balls, and cage around the bearing center.
- Accommodating dynamic misalignment of approximately 0.07 to 0.12 radians (4 to 7 degrees) under normal loads.
- Suitability for challenging installations
- Ideal for applications prone to shaft bending and where aligning the shaft and housing is difficult (such as transmission shafts).
Applications:
- Transmission shafts
- Gearboxes and speed reducers
- Agricultural machinery
- Industrial equipment prone to shaft misalignment
