Enduro Bearing MR 18307 LLB 18x30x7 ABEC 3

Enduro MR 18307 LLB bearing is a reliable ABEC-3 radial bearing designed for hub, bottom bracket (square taper), and pivot applications. The C3 clearance ensures smooth operation in tighter press-fit environments.

It features deep-groove races and Grade 10 balls for consistent performance and durability. LLB dual-lip labyrinth seals provide effective protection against dirt and moisture while maintaining low friction.

Filled 90% with high-pressure waterproof grease, this bearing is built for long-lasting performance in demanding conditions. It is often used as a replacement for 6903 bearings in hubs from DT Swiss, Giant, and Bontrager, with a slightly larger inner diameter.
