The rolling bearing design incorporates at least two antifriction bearings, a fixed supporting centering sleeve and a toothed cage with an extended cylindrical part, extending outside the dimensions of the bearings, and sockets in the form of a crown on both sides of the cylindrical part of the cage. The fixed supporting centering sleeve of the cage incorporates channels for oil supply to the cage. The extended cylindrical part of the cage between the adjacent bearings in the assembly can be made up of two parts with the possibility to slip relative to each other. The invention enables improvement in the reliability, wear-resistance and durability of the bearing assemblies incorporating at least two bearings, including those of different types and sizes, which operate at high speeds and are subject to significant centrifugal loads exceeding the gravity acceleration by hundred times.

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).

An internal combustion engine featuring a radial array of cylinders and pistons; the pistons having rods including cam followers engaging the surface of a cam drive to transfer reciprocating linear motion into rotary motion; wherein between the piston rods and the engine housing are disposed arrays of toothed rollers to provide a rolling interface.

A bearing assembly having an inner race, an outer race, and a plurality of rollers positioned between the inner race and the outer race. A pad is attached to the inner race and a bed is attached to the outer race. A timing mechanism is slidably mounted to the pad and the bed. Preferably the pad and bed are made of plastic and the inner race is embedded within the pad and the outer race is embedded within the bed.

A rolling bearing mechanism comprising a rod (110), an outer ring (130) surrounding the rod coaxially, and rollers (120)interposed between the rod (110) and the outer ring (130), with the rod, the outer ring, and the rollers each having a respective right-handed thread and a respective left-handed thread, the left-handed threads (122a) of the rollers meshing with the right-handed thread (112a) of the rod and with the left-handed thread of the outer ring, and the right-handed threads (122b) of the rollers (120) meshing with the left-handed thread (112b) of the rod (110) and with the right-handed thread of the outer ring (130).

A swash plate bearing is disclosed. The swash plate bearing may have an arcuate cage member having at least one flange and a plurality of rolling elements rotatably coupled to the at least one flange. A coupling seat extends laterally from the at least one flange, the coupling seat may have an insertion hole. A link member may be rotatably coupled to the cage member, the link member having a central portion positioned between a first terminal portion and a second terminal portion. A first stem connects the central portion to the first terminal portion and a second stem connects the central portion to the second terminal portion. The central portion is positioned in the insertion hole.

A drive mechanism for adjusting a position of a vehicle closure, with respect to a vehicle body, is provided. The drive mechanism may include a linear drive and a telescoping arrangement. The linear drive may include a spindle and a spindle nut and the telescoping arrangement may be coupled to the spindle nut and include a pair of gears coupled to one another. As the spindle rotates, the pair of gears may rotate to extend and retract translating portions of the telescoping arrangement in a telescoping manner such that the position of the vehicle closure may be adjusted.

A bearing assembly having an inner race, an outer race, and a plurality of rollers positioned between the inner race and the outer race. A pad is attached to the inner race and a bed is attached to the outer race. A timing mechanism is slidably mounted to the pad and the bed. Preferably the pad and bed are made of plastic and the inner race is embedded within the pad and the outer race is embedded within the bed.

A unidirectional rotary bearing contains a bearing body, multiple rollers, two rotatable driving rings, and at least two homing springs. The bearing body includes an internal surface and two peripheral surfaces, the internal surface has multiple receiving grooves each having an engagement segment and a disengagement segment, and each peripheral surface has a circular groove. Each of the multiple rollers is columnar and has a diameter which is more than an engaging depth of the engagement segment of each receiving groove of the bearing body and is less than a disengaging depth of the disengagement segment of each receiving groove of the bearing body, and each roller has two drive extensions. A diameter of each of the multiple apertures is more than each of the two drive extensions and is less than the diameter of each roller.

A bearing arrangement having: a first element having an inner race and a first bearing surface; a second element, pivotable relative to the first element about a first axis, and having an outer race and a second bearing surface that cooperates with the first bearing surface to form a plain bearing. The bearing arrangement also includes a roller element disposed between the inner and outer races to form a rolling bearing. The inner and outer races are arcuate and subtend an angle of less than 360 about the first axis.
