QJ 307 MA

Designed to manage heavy bidirectional axial loads without hogging installation space, the QJ 307 MA is a powerhouse single-row angular contact bearing built for demanding environments. What sets the QJ 307 MA apart is its split inner ring and unique four-point geometry, allowing it to effortlessly handle thrust in both directions while maintaining a high limiting speed of 15,000 r/min. Thanks to its outer-ring-guided machined brass cage, this specific QJ 307 MA variant keeps friction to an absolute minimum even when centrifugal forces peak. If you're looking to replace bulky double-row setups in compressors or high-speed gearboxes, the QJ 307 MA delivers the exact rigidity and compact footprint modern industrial machinery requires.

We provide sea and air freight services for large bearings, and international express shipping services for small bearings.
