A bearing assembly is for movably coupling first and second members, one being movable relative to the other. A plain bearing section includes an inner ring connectable with the first member and an outer convex bearing surface. An outer ring is disposed about the inner ring and has an inner concave bearing surface disposed against the inner ring bearing surface. The two bearing surfaces are formed such that one bearing surfaces slides against the other when the movable member displaces about a first axis and two bearing surfaces engage to prevent displacement between the two rings when the movable member displaces about a second axis. An elastomeric bearing section is disposed about the plain bearing section, is connected with the second member and formed such that at least a portion of the elastomeric bearing section flexes when the movable member angularly displaces about the second axis.

A tripod constant-velocity joint includes: an outer joint member having a cavity elongated in a longitudinal direction and three roller tracks; an inner joint member having a center body and three journals outwardly radially protruded from the center body; and three roller assemblies respectively coupled to the journal in a state of being respectively disposed in the roller tracks. The respective roller assembly comprises: an inner race which is connected to the journal and is provided with a first inner ball groove and a second inner ball groove on both lateral sides thereof; a first ball array and a second ball array respectively having a plurality of balls which are respectively disposed in the first inner ball groove and in the second inner ball groove; and a ball cage which restricts movements of the first ball array and the second ball array in a longitudinal direction thereof.

The present invention relates to a guiding and centering device (10) for a forming tool (2), in particular an injection molding or die-casting tool, comprising a first mold half (1) and a second mold half (5) which are guided by guide means (7) from a closed position in which the respective separating surfaces of both mold halves (1; 5) are pressed against one another into an opened position and vice versa. This guiding and centering device (10) comprises a protruding guiding body (4) formed as a circular cylindrical bolt (12) provided at the first mold half (1), a guiding recess (6) formed as a bush (14) with an circular cylindrical inner surface (20) provided at the second mold half (5) and a rolling element cage (16) with rolling elements (17) inserted in rows (18), by means of which the two mold halves (1; 5) are guided and precisely centered in the closed position. The rolling element cage (16) is supported by the circular cylindrical inner surface (20) of the bush (14) and positioned via positioning means (30) in such a way that when closing the forming tool the circular cylindrical bolt (12) runs practically simultaneously in a first row of rolling elements (18.1) and a second row of rolling elements (18.2) of the rolling element cage (16).

The synchronized roller with freewheels includes a central body which exposes an outer cylindrical rolling surface provided to roll between two rolling tracks lined with a synchronizing unit, each end of the body presenting a smooth axis about which a synchronizing pinion is freely rotatable, the axis having a pinion axial stop unit which prevents the pinion from emerging from the pinion, while a roller axial guide bears on the central body and on the rolling tracks to keep the outer cylindrical rolling surface approximately centered on the tracks.

In a finite linear motion guide unit, a retainer for retaining rollers rolling between guide members is formed into a V-like shape to thereby increase a rated load. A first guide member is formed into a V-like concave form, and a second guide member is formed into a V-like convex form. Needle rollers are retained by the V-shaped retainer and roll on a raceway formed by facing surfaces of the guide members. The V-shaped retainer includes a pair of roller retainer plate portions for retaining the needle rollers, and a retainer connection portion. A retainer straying prevention mechanism is composed of a pinion disposed in a cross-opening, and racks disposed on the guide members and meshing with the pinion.

A bearing assembly is for movably coupling first and second members, one being movable relative to the other. A plain bearing section includes an inner ring connectable with the first member and an outer convex bearing surface. An outer ring is disposed about the inner ring and has an inner concave bearing surface disposed against the inner ring bearing surface. The two bearing surfaces are formed such that one bearing surfaces slides against the other when the movable member displaces about a first axis and two bearing surfaces engage to prevent displacement between the two rings when the movable member displaces about a second axis. An elastomeric bearing section is disposed about the plain bearing section, is connected with the second member and formed such that at least a portion of the elastomeric bearing section flexes when the movable member angularly displaces about the second axis.

A pivot cradle bearing (1) for an axial piston machine, including a bent cage segment (2), in which rolling bodies are guided, which are arranged between two bearing parts which can be pivoted with respect to one another, wherein a synchronization device (4), which is designed for synchronizing the relative movement of the bearing parts with the displacement of the cage segment (2), includes a pivoting lever (5) which is mounted in the cage segment (2). An articulated bearing (6) is provided for mounting the pivoting lever (5) in the cage segment (2), the articulated bearing having an asymmetrical design with respect to a tangential plane (TE) lying centrally between an inner circumferential surface and an outer circumferential surface of the cage segment (2).

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.

The synchronized roller with freewheels includes a central body which exposes an outer cylindrical rolling surface provided to roll between two rolling tracks lined with a synchronizing unit, each end of the body presenting a smooth axis about which a synchronizing pinion is freely rotatable, the axis having a pinion axial stop unit which prevents the pinion from emerging from the pinion, while a roller axial guide bears on the central body and on the rolling tracks to keep the outer cylindrical rolling surface approximately centered on the tracks.

Provided is a finite stroke type linear guide device including: a guide member (3) including a guide groove (30) and formed into a channel shape; a shaft member (4) configured to move inside the guide groove (30) along a longitudinal direction of the guide groove (30); a large number of rolling elements configured to roll between the guide member (3) and the shaft member (4) while bearing a load; and a cage (5) configured to be arranged inside the guide groove (30) of the guide member (3) so as to be present in a gap between the guide member (3) and the shaft member (4), the large number of rolling elements being rotatably arranged in the cage (5). Stoppers (6) are provided at both ends of the guide member (3) in a longitudinal direction, respectively, and are configured to allow the cage (5) to be brought into abutment against each of the stoppers (6). While the shaft member (4) has a regulating hole (42) which is elongated along a moving direction of the shaft member (4), the cage (5) has a locking protrusion (50) provided upright on the cage (5) and having a distal end part inserted into the regulating hole (42).
