⚙️Product Description:
The MR18307-2RS is a specialized miniature metric radial bearing (18x30x7mm) highly coveted in the premium bicycle industry. It is specifically engineered to handle the high-RPM demands of rear wheel freehub bodies and the repetitive lateral stress of full-suspension mountain bike pivots. As a highly experienced B2B bearing trading company, we distribute these critical drivetrain and suspension components through our own cost-effective RMO brand. To fully accommodate your diverse workshop or assembly line needs, we also maintain a robust sourcing network to provide alternative top-tier bearing brands upon request.
⚙️Product Features:
- High-RPM Capable: Precision-honed internal raceways minimize friction, ensuring immediate and smooth cassette engagement when accelerating.
- Pivot Load Resistance: Built with high-carbon chrome steel balls that resist pitting and wear caused by the micro-rotations and heavy impacts inherent to suspension linkages.
- All-Condition 2RS Sealing: Features dual, tight-fitting rubber contact seals that effectively lock in the premium synthetic grease while keeping out trail mud, degreasers, and water.
- B2B Versatility: Optimize your inventory costs with our reliable RMO brand, or request multi-brand procurement services tailored to specific OEM/aftermarket requirements.
⚙️Product Application:
Renowned for its versatile 18x30x7 profile, the MR18307-2RS is strictly applied in:
- Bicycle rear wheel Freehub Bodies (compatible with many popular hub systems).
- Main pivot points and rocker links on full-suspension Mountain Bikes (MTB).
- Specific lightweight bottom bracket cups and hub shells.
- Professional bike shop drivetrain overhaul kits and suspension rebuilds.
