Overview
FAG 2311-K-2RS-TVH-C3 Self-Aligning Ball Bearing uses two rows of balls and a spherical outer ring raceway to compensate for shaft misalignment. It provides low-friction rotation in fans, conveyors, textile machines, and long-shaft arrangements with mounting or housing deviations.
Two rows of balls are guided by a cage on the inner ring, while the outer ring has a spherical raceway. The design absorbs angular misalignment between shaft and housing while maintaining low friction at moderate to high speeds.
Key features
- Self-aligning function for angular misalignment
- Low friction for stable medium- to high-speed operation
- Suitable for long shafts and deflection-prone positions
- Available in open and sealed variants
Typical applications
- Fans and blowers
- Conveyor shafts
- Textile machinery
- Agricultural and general machinery
Selection guidance
Check expected misalignment, load, sealing needs, internal clearance, and available mounting space.
