A bearing support is configured to retain at least two bearings disposed closely adjacent to each other in a parallel relationship. Each bearing includes a bearing outer ring having a cylindrical outer circumferential surface. The bearing support comprises at least first and second portions that are connected together. The first portion is formed as a component that has cylindrical openings configured to receive or seat the respective bearing outer rings and to surround the entire circumference of the respective bearing outer ring. The second portion is formed as a support plate. A bearing assembly includes the bearing support with a bearing seated in each of the respective cylindrical openings.

A bearing support is configured to retain at least two bearings disposed closely adjacent to each other in a parallel relationship. Each bearing includes a bearing outer ring having a cylindrical outer circumferential surface. A support part includes a recess configured to hold the at least two bearings. At least one junction portion is defined in the support part adjacent portions of the cylindrical circumferential surfaces of the bearings that are not filled by the bearings when the bearings are inserted into the support part. The support part is connected with a cover part that axially abuts on the bearings. The cover part includes at least one support element, which extends into the junction portion between the bearings in the assembled state of the bearing support and at least partially fills the junction portion.

A bearing assembly comprises at least two adjacently-disposed bearings. Each bearing includes a bearing outer ring having a cylindrical outer circumferential surface. A bearing support retains the at least two bearings such that respective rotational axes of the at least two bearings extend in parallel. A spacer has at least two cylindrical openings configured to receive the respective cylindrical outer circumferential surfaces of the bearing outer rings such that a circumferential inner surface of each opening covers at least a portion of a width of the bearing outer ring received therein and surrounds an entire circumference of the bearing outer ring received therein. The bearing support is not fixedly connected to the spacer.

A part-bearing-ring of a rolling-element bearing includes first and second assembly bores on its end surface, and the second assembly bore has a larger diameter than the first assembly bore so that it can accommodate a securing sleeve. The second assembly bore may include an internal thread for attaching the securing sleeve. Also a bearing ring formed of two part-bearing-rings and a securing sleeve and a method of installing a bearing ring.

A bearing having grease lubrication includes a first ring and a second ring. A plurality of screw holes axially extend through the first ring. A first axial end of the first ring is affixed to a housing by a plurality of screws extending from the housing into the respective screw holes. A first bore is defined in the first ring adjacent to a second axial end of the first ring. The first bore intersects and fluidly communicates with one of the screw holes such that grease is dischargeable therethrough.

An injection molding tool for producing a cage for a linear bearing in which several rolling elements are positioned in the cage in the direction of its longitudinal extent in the assembled state includes two tool halves each provided with protrusions. The protrusions extend into the cavity of the tool during the injection molding process and form a portion of a receiver pocket for receiving a rolling element. To make the injection molding process simple and economical, the protrusions are fixedly connected with the tool halves, with the protrusions being are shaped in such a way that, when acting together, they form holding elements for retaining the rolling elements in the receiver pockets in the cage when the injection molding tool is closed. The holding elements are thus integrated into the basic geometry of the cage. A rolling bearing cage for a linear bearing is provided with a plurality of receiver pockets for holding rolling elements next to each other in a manner arranged along the longitudinal extent of the bearing. The cage is also provided with holding elements integrated into the basic geometry of the cage for retaining the rolling elements within the receiving pockets.

A bearing unit includes a housing provided with a cylindrical bore and a linear bearing positioned within the cylindrical bore. The linear bearing includes a cage in which are arranged a plurality of endless ball rows each defined by a longitudinally extending ball track for load-bearing balls, a longitudinally extending return track for non-load-bearing balls, and deflection tracks connecting ends of the longitudinally extending ball track and the longitudinally extending return track. Each longitudinally extending ball track opens radially outwardly with a track plate being arranged to cover the longitudinally extending ball track for the load-bearing balls. The cylindrical bore of the housing is provided with a plurality of recesses each located in an area of the cylindrical bore facing one axial end of one of the track plates to permit radial deflection of the one axial end of the track plate.
