Abstract: An annular element for a rolling bearing comprises a cylindrical surface around the circumference of which a groove, the radial and axial depth of which are variable around the circumference, is formed. The cylindrical surface is suitable for being over-moulded with a plastics material to form a body which is fixed firmly for rotation with the annular element and has a plastics projection complementary with the groove. The projection can cooperate with the groove to prevent relative rotation between the annular element and the body.

Abstract: A precision spindle unit for low friction performance includes a tubular housing surrounding a shaft, and first and second rolling bearings mounted on the shaft within the housing. The first bearing is axially arrested between the flange of a locking washer fixed to the shaft and a shoulder on the shaft. A second locking washer is fitted to the shaft, and a resilient member is provided between the second locking washer and a side of the inner race ring of the second bearing. The axially inwardly facing side of the outer race ring of the second bearing engages an inwardly projecting shoulder in the housing, with the second bearing being biased between the resilient member and the inwardly projecting shoulder. The locking washers define a slot seal at each axial end of the housing to provide a seal at the outwardly facing sides of the first and second bearings.

Abstract: A system and method is provided to accommodate positional variations in a bearing assembly, which has a clearance adjustment assembly for setting the roller clearance therein. The bearing assembly has multiple rows of tapered rollers disposed circumferentially between an inner sleeve and the clearance adjustment assembly, which is secured by an outer retaining sleeve. The clearance adjustment assembly has at least one clearance adjustment ring disposed adjacent multiple tapered support rings, which extend circumferentially about the multiple rows of tapered rollers. In the bearing assembly, the at least one clearance adjustment ring forces the multiple tapered support rings against the multiple rows of tapered rollers to set the desired roller clearance. The bearing assembly also may have seals disposed between the inner sleeve and the outer retaining sleeve at opposite sides of the multiple rows of tapered rollers. In operation, the inner sleeve is mountable to a rotatable member, while the outer retaining sleeve is insertable into a desired bearing mount. For example, the inner sleeve may have a screw mount assembly or an adapter mount assembly, such as a compressive fit mechanism. The outer retaining sleeve may be secured within the desired bearing mount via retaining structures disposed about the outer retaining sleeve at a desired spacing, such as a spacing providing a desired range of longitudinal movement. The desired bearing mount also may have a spherical outer structure, which is pivotally mountable in a spherical mount chamber. Accordingly, the bearing assembly can accommodate expansion, contraction, and angular variations in the system.

Abstract: A bearing assembly comprising an inner ring for mounting on a shaft, an outer ring disposed concentrically about the inner ring, a plurality of roller elements interposed between the inner and outer rings. The inner ring includes fingers which extend axially from a side thereof and terminate in outer annular end walls. A compressible annular locking collar is positioned circumferentially about the fingers. The locking collar has a larger inside diameter and a smaller inside diameter. The larger inside diameter has an axial length not greater than the axial length of the fingers. The larger inside diameter is sized to fit over and engage the fingers. The smaller inside diameter is sized to define an annular radially extending wall which engages the outer annular end walls of the fingers. The locking collar has a fastener screw for causing the larger diameter of the locking collar to compress the fingers into locking engagement with the shaft.

At least one rolling bearing has an inner ring press-fitted to the shaft. The inner ring defines an intermediate portion including an inner raceway surface. A reduced diameter part having an outer diameter smaller than the inner diameter of the inner ring and a predetermined width in the axial direction is formed on the shaft at a position corresponding to the intermediate portion so that inner circumferential surfaces located at both ends of the inner ring in the axial direction are interference fitted to the shaft and the inner circumferential surface at the intermediate portion thereof is clearance fitted to the shaft.
