MR 18307 LLU/LLB A5 SL - Solid-Lube ABEC-5 Radial Bearing (CN Clearance) - 15mm x 26mm x 7mm

Upgrade your bicycle's performance with the MR 18307 LLU/LLB A5 SL Solid-Lube ABEC-5 Radial Bearing. This bearing features a solid, lubricant-infused polymer that replaces traditional grease, effectively eliminating spaces for water or dirt to accumulate, thus enhancing durability and lifespan. Engineered with 52100 high-carbon chromium alloy races paired with grade 10 balls, it offers superior precision and performance. The LLU/LLB seal combination provides optimal protection against contaminants while maintaining lubrication.
