Enduro Zero Ceramic-Hybrid ABEC-5 radial bearing combines black-oxide treated 52100 high-Carbon Chromium alloy races with Grade 5 Silicon-Nitride Ceramic balls at 90% fill. This configuration eliminates steel-on-steel contact, significantly reducing wear while extending bearing life. The magnetite treatment enhances corrosion resistance, while VV seals deliver optimal rotational speed with minimal friction, though offering less environmental protection than LLB or LLU variants. Includes high-pressure, waterproof grease for consistent performance.

This radial bearing serves primarily as a hub component but can function as a pivot bearing, though the MAX variant is superior for suspension applications. Enduro bearings utilize various materials including high-carbon chromium steel, 440C stainless steel, ceramic-hybrid configurations, and XD-15 with ceramic or stainless balls. Engineered with exceptionally deep groove races to accommodate larger balls, these bearings feature innovative dual-lip seals positioned in micro-grooves, creating a comprehensive labyrinth system that delivers enhanced protection against environmental contaminants.
