UNION Ceramic Bearing CB-353 MR17287 LLB 17×28×7

UNION CB-353 MR17287 LLB is a high-quality ceramic ball bearing that offers exceptionally smooth rotation, low rolling resistance, and a long service life. This bearing uses Si3N4 silicon nitride ceramic balls, which are extremely hard, lightweight, and highly resistant to wear.

The bearing's LLB rubber seal (non-contact) effectively protects the bearing from dust and moisture without adding significant friction. This ensures smooth rotation and excellent durability even in demanding conditions.

The bearing comes pre-greased with Kyodo Yushi Multemp PS2, ensuring consistent performance and good heat resistance. It's ideal for bicycle hubs and other rotating components that require the MR17287 size.
