WHAT ARE MAX BEARINGS?Designed specifically for suspension pivots, the bearings pioneered MAX type bearings for bicycles to address the challenges associated with mountain bike pivots.These bearings have 35-40% more load capacity than standard radial bearings.We accomplish this with a special design where the maximum number of balls are inserted into the bearing.The race grooves are deeper on these bearings for more lateral support for the twisting and multiple forces associated with mountain bike pivots.LLU seals give maximum protection against the elements, while keeping the 90% fill of Mobil Grease inside.Item: B543-2RS MAXClosures: Double SealedStructure: MAX, Full Balls, NO Retainer.Dimensions: 39.7 x 50.8 x 7.14 mm ID (inner diameter): 39.7 mmOD (outer diameter): 50.8 mmWidth: 7.14 mmQuantity: 1 Lot = 1 PC
