The ENDURO MR 17287 features a revolutionary Solid-Lube polymer matrix that completely fills internal cavities, preventing contaminant ingress. Constructed with premium 52100 High-Carbon Chromium alloy races and grade 10 balls, these ABEC-5 bearings incorporate strategically deepened grooves to maximize contact surface area, significantly extending operational lifespan. The asymmetric seal configuration employs robust LLU seals externally to defend against environmental elements while utilizing lower-friction LLB seals internally to optimize lubrication retention without compromising rotational efficiency. Engineered specifically for cycling applications at 17 x 28 x 7mm dimensions.

This precision-engineered ENDURO MR 17287 radial bearing primarily serves as a hub component but can function as a pivot bearing, though suspension applications are better served by the MAX variant. Available in multiple material configurations including High-Carbon Chromium Steel, 440C Stainless Steel, Ceramic-Hybrid, and XD15 with either Ceramic or Stainless balls. The distinctive deep groove race design maximizes ball size and contact area for superior load distribution. Dual-lip seals positioned in micro-grooves create a comprehensive labyrinth defense system against environmental contaminants. These 17 x 28 x 7mm ABEC-5 bearings represent advanced cycling component engineering with Solid-Lube technology.
