摘要： A relubricatable idler bushing assembly includes an idler bushing having a hub which is dimensioned to receive an idler pulley. The idler bushing is journaled to an inner bushing by bearings which are disposed in fluid communication with a lubricant passageway. The inner bushing is mounted on a spindle adapted to mount the idler bushing assembly to a support surface. The spindle includes and axial passageway and a radial bore communicating the axial passageway with the exterior of the spindle. One end of the spindle is adapted to be connected to a source of lubricant under pressure for supplying the lubricant to an axial passageway. The radial bore is communicated through a radial bore of the inner bushing with the lubricant passageway to allow lubricant supplied to the spindle to be flow to the lubricant passageway.

摘要： A bearing unit is provided, wherein the outer peripheral surface of the inner race extends outward in the axial direction beyond the end surface of the outer race, and is formed such that the diameter of the outer peripheral surface of the inner race increases in the direction toward the rolling elements, such that when lubrication oil is ejected together with air on the outer peripheral surface of the inner race, the lubrication oil moves over the outer peripheral surface due to centrifugal force and is supplied to the rolling elements, making it possible to secure the amount of lubrication oil supplied per unit time to the inside of the bearing, and thus making it possible to reduce wind noise.

摘要： A rolling bearing for a bearing unit is applicable to so-called under-race lubrication employing an oil air method or an oil mist method. A lubrication oil is supplied toward rolling elements (10) through oil supply channels (21) from a bottom (18) of an annular groove (14) formed in one end face (13) of an inner ring (5). A V-shaped groove (20) is provided along an edge of a raceway groove (8) of the inner ring (5) circumferentially of the inner ring. Outlet ports (25) of the oil supply channels (21) are provided in a recess defined by one of inclined surfaces of the V-shaped groove (20). A space (S) is defined between the outlet ports (25) and the rolling elements (10). A sufficient amount of air flows through the space (S), whereby the lubrication oil is supplied to the rolling elements (10) and the raceway groove (8).
