UNION Ceramic CB-374 6805 LLB Bearing 25×37×7
UNION CB-374 6805 LLB is a high-quality ceramic ball bearing that offers extremely low rolling resistance, high durability, and a long service life. This bearing features Si3N4 silicon nitride ceramic balls, which are exceptionally hard, lightweight, and wear-resistant.
The bearing is equipped with an LLB rubber seal (non-contact), providing effective protection against dust and moisture without adding extra friction. This enhances rotation and makes it an excellent choice for wheel hubs, rims, and bottom brackets.
The bearing comes pre-greased with Kyodo Yushi Multemp PS2 grease, ensuring smooth operation and excellent heat resistance, even under demanding conditions.
