Abstract: A stud type track roller bearing includes a shaft provided with a flange, an annular side plate located in an opposed relationship and fixedly attached to the shaft, a ring fitted onto the flange, a plurality of rollers interposed between the ring and the shaft, a sliding member interposed between the ring and the flange and also between the ring and the side plate, a retainer for retaining the rollers in position. The ring has a pair of opposite flat end surfaces, all of which provide a sliding contact surface. The rollers mainly serve to support the load in the radial direction and the sliding members mainly serve to support the load in the axial direction.

Abstract: An endless rectilinear motion rolling guide unit is provided, consisting of a track rail, a slide unit straddling said track rail and a plurality of cylindrical rollers intervened between the two members, so that said slide unit can make a rectilinear movement on said track rail. A slide bearing holding member having an inwardly and gradually decreasing height toward its one end is provided in a recess having the complementary cavity configuration that is in turn provided on the bottom wall surface of said slide unit. A friction member is secured onto the bottom surface of said slide bearing holding member in slide contact relation with the underlying track rail and the friction member can be longitudinally displaceable in the recess of the slide unit so as to adjust the contact pressure between the friction member and the underlying surface of the track rail due to wedging action deriving from the particular configuration of the insert relative to that of the recess receiving it.
