BlackBearing MAX MR-2153114-2RS full suspension MTB bearing 21.5x31x14 mm steel

The BlackBearing MAX range of bearings has been specifically developed for frame joints. They are suitable for oscillating movements such as those found on MTB frame pivots (link bearings, base bearings, seat stays, etc.), and have more balls than conventional bearings to support heavier loads. The MR2153114-2RS reference will allow you to replace your bearings with dimensions of 21.5x31x14 mm.

They feature 2RS seals that are water and dust resistant, with a higher amount of grease than standard bearings. The mechanical resistance is 30 to 40% higher than the standard, allowing for a longer service life despite the high stresses exerted on this type of bearing.
