Enduro Bearing MR 18307 LLB 18x30x7 ABEC 5

Enduro MR 18307 LLB bearing is a high-precision ABEC-5 radial bearing suitable for hub, bottom bracket (square taper), and pivot applications. The C3 clearance ensures smooth operation even in tighter press-fit conditions.

It features deep-groove races and Grade 10 balls for excellent load handling and smooth rotation. The combined sealing system includes full-contact LLU seals on the outside and low-friction LLB seals on the inside to maximize protection while retaining grease.

Filled 90% with Mobil XHP 222 waterproof grease, this bearing is built for durability in harsh 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.
