摘要： A modular ball bearing retaining cage and a slide guide employing such a cage are disclosed. The cage includes a bridge part having opposed end parts spaced by a mid-section and module strips that are connected to the end parts. Each module strip includes one or more guide strip modules. At least some of the guide strip modules include ball bearings disposed in openings provided in respective guide strip modules. The end parts and the guide strip modules have cooperative coupling elements that permit coupling therebetween. The module strips are disposed in guide tracks defined by walls of inner and outer profiles of the slide guide and the ball bearings run within the guide tracks to allow extension of the inner profile with respect to the outer profile. Stop modules may be coupled to the module strips via coupling elements to limit relative travel of the profiles.

摘要： A wheel rolling bearing unit capable of preventing grease leak even if the interference of the sealing member for sealing the clearance between the inner and outer rings is made small. The wheel rolling bearing unit according to the present invention is equipped with an inner shaft; an outer ring disposed concentrically on the outer peripheral side of the inner shaft; a plurality of balls disposed between these; and a pair of cages for retaining the balls in the circumferential direction. On the inner peripheral surface of each of the pair of cages, a concave section being dented to the outside in the radial direction to hold grease is formed in the range from the axial outside end section to the inside end section.

摘要： A zero clearance bearing assembly comprising a housing defining a generally cylindrical bearing chamber with a pair of ball bearing units disposed therein. One unit is adjacent an axial thrust reaction surface of frusto-conical configuration and a shoulder on an associated shaft urges the unit into engagement with the surface. The other unit is press fit on the shaft and also has a shaft shoulder urging it toward the thrust surface. An air impeller on the shaft urges the same toward the other bearing unit and the thrust unit reacts to both the impeller load and an axial preload spring engaging the other bearing unit. One or both of the bearing units is provided with an improved radial preload device comprising a spring and a pair of circumaxially spaced reaction surfaces opposing the same.
