A bearing arrangement (2) in a manual transmission for transferring torque between at least a first guide surface (14b) on a swivel element (14), which can swivel and which is fixed along the bearing relative to the manual transmission, and a second flat guide surface (19a), which can move in the longitudinal direction relative to the bearing (2) and which is supported with the swivel element (14) so that it can swivel at least in the bearing (2). The bearing holds a selector shaft (4) so that i...

Linear motion device including bearings and valves in which all elements are in rolling contact only, there being no sliding friction. A pair of major rollers is prevented from moving apart by one or more retaining rings, belts or springs, or; two groups of major rings have a retainer roller inserted through them and in rolling contact with their inner peripheries to prevent them from moving apart. One or two separating rollers are interposed between the major rollers or major rings to prevent t...

A guide rail arrangement for connecting two relatively displaceable components comprising a lower rail (1) and an upper rail (2) supported thereon by rolling elements (3), said lower and upper rails being configured as rectilinear sheet metal profiles, one of the lower and upper rails partially surrounding the other of the lower and upper rails, whereby hollow spaces are formed for receiving the rolling elements (3) and further slide elements (4) arranged between the rails is characterized in th...

A roller for a bearing used in a linear movement rolling guide apparatus is tumbled after superfinishing the outer peripheral surface so that the surface roughness of the roller in a circumferential direction is in a range from 0.05 to 0.10 micrometers in average roughness on the center line. The surface roughness in the circumferential direction of the outer peripheral surface of the roller is substantially equal to or slightly larger than the surface roughness in the axial direction of the out...

The member (3) is mounted on the shaft (2) which has two flat faces (7), by means of an outer ring arrangement (9) of needles parallel to the axis (X--X) of the shaft and rolling along two half-moon shaped members (8) which complete the circular section of the shaft. Each half-moon shaped member has a longitudinally extending groove (13) which receives a row of needles (12) which are perpendicular to the axis (X--X) and roll along a face (7) and are maintained by a cage (18). Two springs (21) re...

In a rolling bearing for rectilinear movement which is made by thin steel plates, the thickness of thin steel plates of table and bed are set to be thicker than those of conventional ones in order to provide rigidity, then the steel plates are formed due to press forming so as to have U-shaped cross sections. Track grooves each having a V-cross section are formed in the side walls of the table and bed. The V-shaped track grooves are subjected to cutting work and heat treatment and thereafter the...

A linear recirculating roller bearing assembly comprises a bearing body having a load bearing surface and a return surface disposed substantially parallel to each other and defining a path for continuous recirculating movement of roller bearings thereabout. A plurality of substantially identical roller bearings are disposed along the path in engagement with the aforementioned surfaces. Each of the roller bearings has a longitudinal axis and includes at least two cylindrical load bearing portions...

An idler guide for a rotary drilling rig has a plurality of spring-loaded floating bearings along the inside wall of a cylindrical bearing member for stabilizing and guiding the rotational and axial movement of drill pipe through the guide. The floating bearings are spring-loaded to move inwardly or outwardly along the radius of the cylindrical bearing to accommodate both new and worn drill steel pipe. The bearings are free to rotate with any resultant combination of axial or rotational movement...

This mounting system features a base displaced from a mounting plate which is used to anchor a base mounted receiver releasably. The base has a pair of flexible arms to engage the receiver in channels that have a catch edge at the ends of the channels. The base is constructed with at least one stabilizer element and the receiver has an appropriate alignment slot. Each mounting plate, on both the base and receiver, have a plurality of apertures to facilitate attachment to fabric or a fabric patch...

An endless sliding guide apparatus including a track rail, a sliding table having an endless track comprising a load rolling path, a no-load rolling path and a change direction path and rolling bodies wherein at least one of the no-load rolling path, the inner peripheral portion of the change direction path and a rolling body retaining section of the load rolling path is formed by synthetic resin rolling body guide members formed by insert molding using a bearing race as a core. The rolling body...
