Bearing Enduro Bearings 3900 LLU MAX ABEC 3 Double Row

3900 LLU MAX – MAX-design, double-row, angular-contact suspension bearing, measuring 10mm x 22mm x 10mm.

Enduro Bearings pioneered MAX-type bearings for bicycles over 20 years ago to address the demands of mountain bike suspension 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 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 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 bearing line includes bearings made from high-carbon chromium steel and 440C stainless steel, ceramic-hybrid bearings, and XD-15 bearings with ceramic or stainless steel balls. The 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 that protects against the elements.
