In standard radial bearings, only 3 or 4 balls make contact during the load, at any given time. In Angular Contact (A\/C) bearings, ALL balls are engaged and spread the force over a larger surface area, to decrease friction, and minimize wear. Wheel play can be adjusted out of the hub, to giving a more stable wheel, making it easier to adjust disc brakes, while still spinning freely.\u003c\/p\u003e \n \n\u003cp\u003eLoad side on the \u003cb\u003eRED\u003c\/b\u003e seal, 5-10 lbs preload required\u003c\/p\u003e \n \n\u003cp\u003eTypical Application: Bottom Bracket\u003c\/p\u003e \n \n\u003cp\u003eEnduro ABEC-5 Specification:\u003c\/p\u003e \n \n\u003cp\u003eGrade 5 Chromium Steel Balls\u003cbr\u003e \nHigh precision balls are within 5\/1,000,000″ round.
