摘要： A ball retainer includes a chain belt, a hook, and a slot portion. The hook is arranged on the first end of the chain belt. The hook includes a neck portion, a hook body, two leaning protrusions, and a limiting protrusion. The hook body is connected to the neck portion. The two leaning protrusions extend outward along the short side direction of the chain belt toward two sides of the hook body, respectively. The slot portion is arranged on the second end of the chain belt. The slot portion includes a slot, two abutting portions, a connecting portion, and a receiving portion. After the hook is correspondingly engaged with the slot portion, the hook body is accommodated in the slot, the two leaning protrusions correspondingly lean against the two abutting portions, the neck portion leans against the connecting portion, and the limiting protrusion is correspondingly accommodated in the receiving portion.

摘要： A rolling bearing includes an outer ring and an inner ring, a rolling element disposed in a rollable manner between the outer ring and the inner ring, a cage holding the rolling element, and a shield. The outer ring includes a raceway surface supporting the rolling element in a rollable manner, recess parts formed at both direction sides in an axial direction with respect to the raceway surface, and a ridge part formed between the recess part and the raceway surface. The recess part includes a placement surface for placing a grease, and a first inclined part formed between the placement surface and the ridge part and approaching an outer peripheral surface of the outer ring toward an outer side in the axial direction.

摘要： A linear guide device includes a rail that has a first advancing device extending along a longitudinal direction, a carriage that can be displaced relative to the rail along the longitudinal direction and has a second advancing device extending along the longitudinal direction, a cage that can be displaced relative to the rail and the carriage along the longitudinal direction and a coupling element that is designed for simultaneously engaging into the first and the second advancing device in order to cause a movement of the cage relative to the rail and/or the carriage when the carriage is advanced relative to the rail along the longitudinal direction. The coupling element has at least one projection that interacts with a stopping face formed on the rail and/or the carriage in order to retain the coupling element in the linear guide device.

摘要： A two-part bearing cage for a rolling bearing includes a first cage part and a second cage part. Each cage part includes an annular base body with a plurality of bars extending axially from the annular base body and/or a plurality of complementarily designed bar receptacles. The bars of one cage part engage in the bar receptacles of the other cage part to form cage bars for defining cage pockets configured to receive the rolling elements of the rolling bearing. Each bar includes a claw and each bar receptacle includes a connection portion such that each connection portion and its corresponding claw form a snap joint.

摘要： A ball bearing includes an inner ring; an outer ring placed outside of the inner ring; a plurality of rolling bodies intervening between the inner ring and the outer ring; and an annular cage including pockets rotatably holding the rolling bodies in a circumferential direction at intervals determining a rotation axis to be a center. The cage comprises a resin composition comprising a polyetherketone-based resin, graphite, and a carbon fiber. The resin composition comprises the polyetherketone-based resin in an amount of 60% by weight or more and 80% by weight or less, the graphite in an amount of 10% by weight or more and 30% by weight or less, and the carbon fiber in an amount of 5% by weight or more and 20% by weight or less when the entire resin composition is determined to be 100% by weight.

摘要： A bearing unit may be provided with at least one row of rolling bodies and at least one cage for retaining the rolling bodies. The at least one rolling cage may include a base rib; a plurality of fingers spaced circumferentially and extending at least from one side of the base rib; and a plurality of partially spherical cavities for holding the rolling bodies, each cavity being defined by the partially spherical concave surfaces of a pair of fingers of the plurality of fingers and of the base rib. The rolling bodies and the cages are in contact with each other via a plurality of protrusions formed on the partially spherical concave surfaces of the fingers and of the base rib. At least one lateral protrusion may be formed along the surface of each finger of the plurality of fingers of the retaining cage.
