Product Details
An Enduro MR 18307 radial cartridge bearing with ABEC-5 precision and C3 clearance. It has deep-groove races and Grade 10 balls. Full-contact LLU seals face outward to keep out water and grit, lighter-contact LLB seals face inward, and it's packed 90% full of Mobil XHP 222 waterproof synthetic grease. It's commonly used as a hub bearing, including as a replacement for bearings marked 6903 in some DT Swiss, Giant and Bontrager front hubs (note the ID is 1mm larger than a standard 6903).
- ABEC-5 precision with C3 clearance, suited to tighter press-fit bores
- Outer LLU contact seals and inner LLB labyrinth seals
- 90% fill of high-pressure waterproof synthetic grease
- Common hub bearing; also fits some older square-taper BBs
- Sold individually
