Enduro Bearings MR 22378 LLB bearing

Description

When your bottom bracket starts creaking or losing its smooth feel, it takes the joy out of every ride. Enduro Bearings MR 22378 LLB restores a quiet, confident crank rotation, even in wet conditions.

Main benefits

This bearing with an extended inner flange fits precisely on the left, non-drive side of SRAM GXP cranks in externally mounted bottom brackets. It helps maintain correct positioning and stability under load.

Races made from 52100 chrome steel and ABEC-3 precision support smooth operation and consistent ball contact in the raceway. You’ll appreciate it on long climbs as well as during quick pace changes.

Dual-lip LLB sealing creates an effective barrier against water and contamination. The inside is packed with high-pressure, water-resistant grease for longer service intervals.

C3 internal clearance accounts for real-world operating conditions and riding temperatures. The bearing remains refined even under higher bottom bracket loads.

Technical specifications

The bearing’s outer diameter is 37 mm for externally mounted bottom brackets.

The bearing’s inner diameter is 22 mm for the non-drive side of the SRAM GXP system.

Conclusion
