UNION Ceramic Bearing CB-377 6806 LLB 30×42×7
UNION CB-377 6806 LLB is a high-quality ceramic ball bearing that offers extremely low rolling resistance, excellent durability, and a long service life. The bearing features Si3N4 silicon nitride ceramic balls that are lightweight, incredibly hard, and highly resistant to wear.
This bearing uses an LLB rubber seal (non-contact), which efficiently protects the bearing from dirt and moisture without creating additional friction. This makes it an excellent choice for bicycle bottom brackets and other precision rotating components.
The bearing is lubricated with Kyodo Yushi Multemp PS2 grease, ensuring smooth operation and excellent heat resistance even under heavy use.
