The BlackBearing MAX bearing range has been specifically developed for frame pivots. They are adapted to oscillating movements such as on MTB frame pivots (linkage bearings, horizontal bushing bearings, vertical bushings, etc.) and have more balls than conventional bearings to support higher loads.
Waterproof and dustproof 2RS seals are available, with a greater quantity of grease compared to standard bearings. Mechanical strength is 30 to 40% higher than standard, allowing for greater longevity despite the high stresses exerted on this type of bearing.
