Overview
FAG QJ315-N2-MPA-C3 Four-Point Contact Ball Bearing is a compact angular contact design that can support axial load in both directions and a portion of radial load in a single bearing. It suits gearboxes, cranes, and rotary tables where axial space saving and shaft location are required.
A split inner ring or specially shaped raceway allows the balls to contact at four points. It can replace certain paired angular contact arrangements while reducing axial width.
Key features
- Supports bidirectional axial load
- Saves axial installation space
- Separable design improves mountability
- Suitable for locating bearing positions
Typical applications
- Industrial gearboxes
- Cranes and hoists
- Rotary tables
- Pump and compressor shaft supports
Selection guidance
Confirm axial load dominance, radial load ratio, speed, internal clearance, and the companion bearing arrangement.
