FAG QJ308-XL-MPA is a four-point contact ball bearing with a split inner ring and a solid brass cage. Four-point contact bearings are designed to carry axial loads in both directions and can also support radial loads. The split inner ring design allows the bearing to accommodate axial loads from either direction using a single bearing, making it a compact alternative to matched angular contact bearing pairs in certain applications. This bearing is open (no seals) and features an X-life optimized internal construction for improved performance, longer service life, and reduced heat generation.

Typical Applications

Commonly used in:

• Gearboxes and transmissions
• Machine tool spindles and rotary tables
• Pumps, compressors, and industrial drives
• Applications requiring axial load capacity in both directions in a compact bearing arrangement
