  • Method of producing rolling bearing device
    Patent number: 7832940
    Abstract: An inner ring is fitted on one-end side of an inner shaft and fixed to the inner shaft by caulking. During the caulking, the inner shaft is supported by a caulking receiving jig. A receiving section to which the jig is in contact is provided at a position near the one-end side of the inner shaft, for example, at a position nearer to the inner ring than a raceway section formed on the outer periphery on the other side of the inner shaft. As a result, a caulking load acting from a caulking jig on the inner shaft plastically deforms only a desired portion.

  • Seal device with sensor and rolling bearing device using the seal device
    Publication number: 20070177834
    Abstract: A seal device with sensor (7) is configured by a fixed side seal member (8) fixed to a vehicle body side raceway member (3) and a rotating side seal member (9) fixed to a wheel side raceway member (4). The fixed side seal member (8) includes a core metal (21), a resin member (22) integrated with the core metal (21) through insert molding, a sensor (11) resin molded to the core metal (21), and an elastic seal (65) adhered to the core metal (21). The core metal (21) of the fixed side seal member (8) includes a fitting cylindrical part (61) fitted and fixed to the vehicle body side raceway member (3), a coupling part (62) extending towards the cylindrical part (31) of the rotating side seal member (9) and a moisture entering prevention cylindrical part (65) extending outward in the axial direction in continuation with the coupling part (62), and the outer end part in the axial direction of the fitting cylindrical part (61) is positioned in the resin (22).
