摘要： A bicycle bearing system comprising: an integrated cup, the integrated cup having an outer diameter; a plurality of rolling elements configured to abut and rotate against a first race groove located on an inner surface of the integrated cup; a second race groove configured to abut and rotate about the plurality of rolling elements, the second race groove located on an inner surface of the inner race, the inner race having an inner diameter; where the rolling elements do not have a separate outer race, but rather the inner surface of the integrated cup acts as the outer race to the rolling elements; and where the rolling elements, integrated cup and inner race are axially locked when assembled as a single cartridge unit due to the geometry of the rolling elements, first race groove and second race groove.

摘要： A tapered roller bearing includes an inner ring with a large rib, an outer ring, and multiple tapered rollers. Each of the tapered rollers has, at its axial end, a large end face that is a convex surface. The large rib has a rib face that is a concave surface and that is in contact with the large end face. When a distance from a position of contact between the large end face and the rib face to a cone center of the corresponding tapered roller is defined as R, a curvature radius of the large end face is defined as Rr, and a curvature radius of the rib face is defined as Ri, an inequality represented by 2≤(Ri −R)/(R−Rr)≤10 is satisfied, where Rr

摘要： Provided is a resin cage for a tapered roller bearing in which a mold parting line which is extended in an axial direction is formed in a pillar portion defining a pocket. On facing surfaces of adjacent pillar portions, on an outer diameter side from the mold parting line, a first conical surface which slides in contact with an outer peripheral surface of a tapered roller is formed, and a first flat surface in a radial direction is formed in a portion on the outer diameter side from the first conical surface. On an inner diameter side from the mold parting line, a second conical surface which slides in contact with the outer peripheral surface of the tapered roller is formed, and a second flat surface in a radial direction is formed in a portion on the inner diameter side from the second conical surface.

摘要： A ball bearing not allowing locations where the surface pressure becomes locally higher at a race at the time of a high load and thereby keeping cracking from occurring and in turn realizing a longer lifespan is provided. A pair of races (12, 14) and at least one rolling element (16) movably clamped between the pair of races move are provided. A cross-sectional profile line (14a) of a part of each of the pair of races contacting the rolling element has the smallest radius of curvature at a position (P) sticking out the most in the first direction (D1) over which the pair of races face. The cross-sectional profile line becomes larger in radius of curvature the further from the position (P) in a second direction (D2) vertical to the first direction (D1) in the cross-section. The cross-sectional profile line is comprised of a single function. When a midpoint of the profile line in the second direction is the origin, an axis extending in the second direction is the X-axis and the axis extending in the first direction is the Y-axis, and a radius of the rolling element is (R), the cross-sectional profile line satisfies equation (1): X2/{2R(1+0.05)}

摘要： A cage has an annular portion positioned on an axially first side of balls and a plurality of cage bars provided to extend from the annular portion toward an axially second side. Pockets each housing a corresponding one of the balls correspond to areas each located on the axially second side of the annular portion and between two cage bars adjacent to each other in a circumferential direction. Each of the balls is exposed from axially-second-side ends of the corresponding cage bars over an axially-second-side range. An axial dimension of the range over which the ball is exposed from the axially-second-side ends is 30% or more and 50% or less of the diameter of the ball.
