Enduro Bearings' S6902 LLU MAX Stainless ABEC-3 Radial Suspension Bearing represents two decades of innovation in bicycle component engineering. These MAX-type bearings deliver 35-40% increased load capacity through a proprietary design featuring maximum ball quantity insertion via custom-ground race slots. The deep race grooves provide superior lateral support against the multi-directional forces typical in mountain bike pivots. Constructed with precision Grade 10 balls and protected by full-contact, double-lip labyrinth seals, this bearing effectively shields its 90% Almagard high-pressure grease fill while withstanding demanding environmental conditions.

Not all stainless steel is created equal.

The Enduro S6902 LLU MAX utilizes premium 440C stainless steel for both balls and races, delivering exceptional corrosion resistance in challenging environments. This high-carbon stainless variant stands out within the 440-series for its superior hardness, strength, and wear resistance properties. Achieving these mechanical advantages requires sophisticated manufacturing processes including multiple heat treatment cycles and cryogenic processing. While 440C stainless exhibits approximately 20% lower load capacity and slightly reduced hardness compared to standard 52100 chromium steel bearings, it excels in applications exposed to moisture, frequent washing, or perspiration contamination.

The Enduro S6902 LLU MAX bearing has been adopted by premium manufacturers like Santa Cruz for suspension pivot applications. Enduro's comprehensive bearing lineup encompasses high-carbon chromium steel, 440C stainless steel, ceramic-hybrid configurations, and advanced XD-15 variants with ceramic or stainless ball options. Engineering excellence is evident in the maximized race groove depth, accommodating larger ball bearings for enhanced performance. The sophisticated dual-lip seal design incorporates a precision micro-groove interface, creating a complete labyrinth barrier that delivers exceptional protection against environmental contaminants.
