A bearing assembly having cylindrical rolling elements, an inner ring, an outer ring, and a plurality of cylindrical rolling elements arranged radially between the internal raceway and external raceway. The inner ring includes an annular shoulder that protrudes with respect to the internal raceway, a fillet in the form of a circular arc being defined between the annular shoulder and internal raceway. The outer ring has an annular shoulder that protrudes with respect to the external raceway, the annular shoulder of the outer ring being housed axially between the annular shoulder of the inner ring and the cylindrical rolling elements. The annular shoulder of the outer ring is provided with an annular chamfer in the immediate vicinity of the fillet defined on the inner ring.

A bearing assembly includes a bearing cage and a supplementary ring. The bearing cage includes an annular body and a plurality of bearing elements disposed about the annular body. The supplementary ring includes an annular collar and a plurality of retention elements. The annular collar is disposed concentrically about the bearing cage. The plurality of retention elements is connected to and extends axially from the first annular collar. Each retention element is aligned between adjacent bearing elements. The plurality of retention elements is disposed to retain the plurality of bearing elements in the annular body of the bearing cage.

A two-part ball bearing cage includes two, in particular at least substantially identical, cage parts forming an even-numbered plurality of ball pockets for receiving a corresponding number of balls having a predeterminable ball diameter. Each cage part has an annular body on which substantially evenly distributed webs are disposed in the circumferential direction to form the ball pockets. A distance in the circumferential direction between two webs that are adjacent in the circumferential direction approximately corresponds to the sum of twice the ball diameter and a width of the web in the circumferential direction. A ball bearing having the ball bearing cage and a method for assembly of the ball bearing are also provided.

A ball bearing having the ball bearing cage and a method for assembly of the ball bearing are also provided.

A cage of a roller bearing includes at least two cage segments, wherein each cage segment is formed from two side pieces, which are disposed at an axial distance from one another, and from a plurality of webs that are circumferentially distanced from each other and that connect the side pieces in the axial direction, wherein each cage segment forms an arc of a given arc length, the plurality of webs includes a center web, which maintains a distance of half the given arc length from the circumferential ends of the respective cage segment, and wherein the center web is penetrated by a bore the center axis of which approximately runs through the center of gravity of the cage segment, and which is configured to accommodate a radially outwardly directed moving device in a releasable manner.

The invention relates to a rolling element bearing cage formed of one or more segments, each segment comprising: a supporting frame having a plurality of spaced apart openings each for accommodating a rolling element; and a reinforcing frame, inserted within the supporting frame, having a corresponding plurality of openings each for aligning with the openings of the supporting frame.

An auxiliary assembly device is provided for premounting a linear guide system on a top part. The linear guide system includes two linear guides having two respective mutually displaceable guide rails, which have mutually facing raceways. Rolling elements, which are disposed in a cage, are located between the mutually facing raceways. The auxiliary assembly device has an auxiliary rail, which is configured for connection to a respective narrow end of the two linear guides in order to hold the two linear guides with the top part in a preassembled state for insertion into a bottom part. A method for premounting a linear guide system on a top part is also provided.

The present invention discloses a bearing ball assembly device comprising a steel ball output unit, a steel ball control unit and a steel ball assembly unit, wherein said steel ball output unit is connected to said steel ball control unit, said steel ball control unit is connected to said steel ball assembly unit, said steel ball output unit delivers steel balls to said steel ball control unit, said steel ball control unit allows a certain number of steel balls to enter said steel ball assembly unit each time, and said steel ball assembly unit embeds steel balls in a bearing retainer. The present invention automatically realize the process of embedding of steel balls in a bearing retainer.
