Bearing Enduro Bearings 3901 LLU MAX ABEC 3 Double Row

3901 LLU MAX – MAX-design, double-row, angular-contact suspension bearing, 12mm x 24mm x 10mm.

Enduro Bearings pioneered MAX-type bearings for bicycles 20 years ago to address the challenges associated with mountain bike pivots. MAX bearings provide 35-40% more load capacity than standard angular-contact bearings. Their special design allows the maximum number of balls (full-complement) to be inserted into the bearing through a custom-ground slot in the races. The race grooves are also deeper to provide increased lateral support against the twisting and multidirectional forces associated with mountain bike pivots.

This MAX-type, double-row, ABEC-3 bearing features deep-groove races, Grade 10 balls and full-contact, double-lip labyrinth (LLU) seals for maximum protection against the elements, while retaining the 90% fill of Almagard extra-high-pressure grease inside. The double-row design greatly reduces flex in the suspension linkage while doubling the bearing contact area.

This bearing is most commonly used as a suspension pivot bearing.

The Enduro line of bearings is available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD-15 with ceramic or stainless steel balls. The bearings are engineered with the deepest grooves possible to accommodate the largest balls and feature dual-lip seals that ride in a micro-groove, creating a full labyrinth for superior protection against the elements.
