The ENDURO MR 15267 features a revolutionary Solid-Lube polymer system that completely fills internal cavities, preventing contaminant infiltration. 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 and extend 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 and performance in demanding cycling applications.

This precision-engineered radial bearing primarily serves as a hub component but can function as a pivot bearing, though the MAX variant offers superior suspension performance. Enduro's diverse material options include High-Carbon Chromium Steel, 440C Stainless Steel, Ceramic-Hybrid, and XD15 configurations with either Ceramic or Stainless ball bearings. The distinctive deep groove race design maximizes ball size for optimal load distribution and durability. Advanced dual-lip seals operate within precision micro grooves, creating a comprehensive labyrinth defense system that effectively shields internal components from environmental contamination.
