  • Patent number: 8876396
    Abstract: A roller bearing includes an outer ring having a substantially cylindrical internal bearing surface and an outside surface defining a plurality of protuberances. A protective coating is applied to the outside surface of the outer ring. An inner ring is coaxially disposed at least partially in the outer ring and has a substantially cylindrical external bearing surface. The external bearing surface and the internal bearing surface define an annular cavity in which a plurality of rolling elements is disposed. The rolling elements are in rolling engagement with the external bearing surface and the internal bearing surface. The outside surface of the outer ring can be case hardened, for example the outer ring can be carburized. The outside surface of the outer ring can be knurled. A method of manufacturing such a bearing is also disclosed.

  • Patent number: 8827560
    Abstract: A shaft, which supports an inner ring of a bearing and is integrally attached to a linear motion type slider, has a through hole in a center portion thereof. Since correction of the shaft may be performed by grasping a separate shaft to be inserted to the through hole, the shaft is not scratched. Additionally, even after press fitting the bearing, the posture may be corrected without grasping the bearing.

  • Patent number: 8132964
    Abstract: A bearing includes an inner race member having an end surface. An outer race member is disposed about the inner race member. The outer race member has an internal shoulder for engaging the end surface of the inner race member. The inner and outer race members are configured to define a raceway between them and to define a snap ring seat between them. There are cylindrical rollers in the raceway and a snap ring in the snap ring seat. The bearing may be provided as a follower head on a cam follower or may be eccentrically mounted on a drive shaft to serve as a cam. A bearing can be assembled by inserting the inner race member into the outer race member, disposing cylindrical rollers in the raceway and disposing a snap ring in the snap ring seat.
