Bearing Enduro CH 6901 LLB 12×24×6 ABEC-5, Ceramic-Hybrid

The Enduro CH 6901 LLB is an ABEC-5 rated ceramic hybrid radial bearing, engineered for exceptionally smooth rolling, low friction, and long service life. It features oversized Silicon Nitride Grade 5 ceramic balls, which significantly reduce friction and wear compared to conventional steel balls.

Ceramic bearings are no longer a future concept – they are now the standard. Just as carbon fiber replaced steel in top-level racing bicycles, ceramic bearings have become a proven performance solution. The Enduro CH series is an excellent entry into ceramic bearing technology, delivering premium performance 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, quiet operation even at high rotational speeds.

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

Like all Enduro bearings, the CH 6901 LLB is engineered with the deepest possible race grooves to accommodate larger balls, ensuring optimal load distribution, smooth rotation, and long-lasting performance.
