FAG QJ312-XL-MPA-C3 四点接触玉軸受 60 × 130 × 31 mm

Overview

FAG QJ312-XL-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.

Selection guidance

Confirm axial load dominance, radial load ratio, speed, internal clearance, and the companion bearing arrangement.
