BlackBearing MAX 6903-2RS full suspension MTB bearing 17x30x7 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 6903-2RS reference will allow you to replace your bearings with dimensions of 17x30x7mm.

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