Bearing Enduro CH MR 2437 LLB 24x37x7 ABEC-5, Ceramic-Hybrid

The Enduro CH MR 2437 LLB is an ABEC-5 rated ceramic hybrid radial bearing, engineered to deliver exceptionally smooth rolling, low friction, and long service life. It features oversized Silicon Nitride Grade 5 ceramic balls, significantly reducing friction and wear compared to conventional steel balls.

Ceramic bearings are no longer a future technology – they are now the standard. Just as carbon fiber replaced steel in elite-level racing bicycles, ceramic bearings have become a proven performance upgrade. The Enduro CH series is an excellent entry point into ceramic bearing technology, offering premium features at outstanding value.

This bearing is equipped with LLB-type double-lip seals with light contact, forming an effective labyrinth sealing system that protects against contamination while maintaining extremely low drag. A graphite-reinforced nylon retainer ensures stable and quiet operation even at high rotational speeds.

The ABEC-5 precision races are cryogenically treated to enhance material structure and extend bearing life. These premium features set Enduro ceramic hybrid bearings apart from many competitors, who do not offer comparable quality even at two to five times the cost.

Like all Enduro bearings, the CH MR 2437 LLB is engineered with the deepest possible race grooves to accommodate larger balls, ensuring optimal load distribution, smooth rotation, and long-lasting performance.
