MAX type bearings are designed specifically for suspension pivots. Using a special design where the maximum number of balls are inserted into the bearing they have more load capacity than standard radial bearings The race grooves are deeper on these bearings for more lateral support for the twisting and multiple forces associated with suspension pivots. LLU seals give maximum protection against the elements while keeping the 90% fill of Almagard Extra High Pressure Grease inside.90% filled with Mobilux NGLI 2 synthetic grease dual-lip labyrinth seals full complement of bearings up to 45% increased load capacity
