Double-row bearing Enduro Bearings 3801 LLU MAX ABEC 3

3801 LLU MAX – MAX-design, double-row, angular-contact suspension bearing – 12mm x 21mm x 8mm.

Enduro Bearings pioneered MAX-type bearings for bicycles more than 20 years ago to address the challenges associated with mountain bike pivots. MAX-type bearings provide 35-40% more load capacity than standard angular-contact bearings. Their special design allows the maximum number of balls to be inserted into the bearing through a custom-ground slot in the races. The additional balls, together with the deep race grooves, provide greater lateral support against the twisting and multidirectional forces associated with mountain bike pivots. This ABEC-3 bearing features deep-groove raceways, Grade 10 balls, and full-contact, double-lip labyrinth (LLU) seals for maximum protection against the elements, while keeping the 90% fill of Almagard extra-high-pressure grease inside. The extra-wide double-row design greatly reduces flex in the suspension linkage while doubling the bearing contact area.

This bearing has been used as a suspension pivot bearing by Trek and Devinci.

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