A furniture lubricant for coating a linear lacquered furniture slide bar to provide a slide layer with lowered friction. The furniture lubricant comprises a C10 to C28 alkane and a tri-glyceride. The viscosity, according to ISO 3104:1994/COR 1:1997, of the furniture lubricant at 40° C. is 20 to 80 mm.sup.2/s.

An adjustable stroke mechanism has a housing with a central axis and a wall enclosing a cavity. At least one counterweight is movably disposed within the cavity. A mounting assembly is disposed within the cavity. The mounting assembly has a workpiece attachment mechanism. A stroke adjustor couples the at least one counterweight with the mounting assembly. The stroke adjustor enables the counterweight and mounting assembly to move with respect to one another such that a distance between the counterweight and the mounting assembly is variably adjusted which, in turn, variably adjusts a stroke radius of the workpiece attachment mechanism with respect to the central axis of the housing.

A bearing assembly for rotatably supporting a rotating body on a frame may include a bearing support block having a plurality of block mounting bores for each being axially aligned with a bearing mounting hole formed in the frame, and at least one mounting bolt removably insertable into one of the block mounting bores and into a bearing mounting hole, with the mounting bolt having exterior threads for threading into interior threads on one of the bearing mounting holes on the frame. One block mounting bore may have interior threads formed thereon, and the interior threads of the block mounting bore may incompatible with the exterior threads of the mounting bolt such that the mounting bolt is not threadable into the block mounting bore. An apparatus and system is also disclosed.

A cutting bur assembly including a cutting head with a head shaft extending therefrom. The cutting head and the head shaft are rotatable by a motor. A tube with the head shaft is rotatably mounted therein. The head shaft extends out from within the tube to locate the cutting head beyond a distal end of the tube. A plurality of bearing rollers are in direct cooperation with an outer surface of the head shaft such that upon rotation of the head shaft the plurality of bearing rollers roll along the outer surface. An outer bearing race surrounds the plurality of bearing rollers and the head shaft to retain the plurality of bearing rollers in cooperation with the head shaft.

A bearing includes a plurality of rolling elements (26) spaced around a three-hundred and sixty degree circumferential extent of the bearing. An odd, non-singular number of high-points are positioned as near to evenly as possible about the circumferential extent of the bearing, the high-points defined by locations at which rolling elements with the largest diameters are positioned. An odd, non-singular number of low-points are positioned as near to evenly as possible about the circumferential extent of the bearing, the low-points defined by locations at which rolling elements having the smallest diameters are positioned. The odd, non-singular number of high-points is the same as the odd, non-singular number of low-points, and each low-point is positioned as near to evenly as possible between two adjacent high-points.

A slider assembly (10) for a transportation system (100) for transporting an object (101) is provided. The slider assembly (10) comprises a first support (12a) and a second support (12b), a first guiding element (14a) arranged on the first support (12a) and a second guiding element (14b) arranged on the second support (12b), wherein the first guiding element (14a) is configured to receive a first rail (104a) and the second guiding element (14b) is configured to receive a second rail (104b), such that the slider assembly (10) is slidably arrangeable on the first rail (104a) and the second rail (104b). The slider assembly further comprises a tolerance compensation element (18), which connects the first support (12a) and the second support (12b), such that at least a part of the first support (12a) and at least a part of the second support (12b) are spaced apart from each other, thereby allowing a relative movement of the first support (12a) and the second support (12b) with respect to each other.

A machining control system for machining of a workpiece movably supported by a motion guidance device having a track member which extends along a longitudinal direction and a moving member which is arranged so as to oppose the track member via a rolling element being rollably arranged inside a rolling groove and which is relatively movable along the longitudinal direction of the track member, the machining control system including: an acquisition unit which acquires prescribed machining information related to a load applied to the motion guidance device when machining of the workpiece is performed by the machining device; and an output unit which generates machining correction information for correcting a prescribed control parameter for machining of the workpiece by the machining device on the basis of the prescribed machining information acquired by the acquisition unit and which outputs the generated machining correction information to a side of the machining device.

An actuator is equipped with a body and a slider. Body side rail grooves are formed in side wall portions that constitute the body. On the other hand, slider side rail grooves are formed in the slider. Body side guide rails and slider side guide rails are provided in the body side rail grooves and the slider side rail grooves, respectively. Circular arc grooves serving as ball grooves are formed by body side ball receiving portions of the body side guide rails, and slider side ball receiving portions of the slider side guide rails.

A cutting bur assembly including a cutting head with a head shaft extending therefrom. The cutting head and the head shaft are rotatable by a motor. A tube with the head shaft is rotatably mounted therein. The head shaft extends out from within the tube to locate the cutting head beyond a distal end of the tube. A plurality of bearing rollers are in direct cooperation with an outer surface of the head shaft such that upon rotation of the head shaft the plurality of bearing rollers roll along the outer surface. An outer bearing race surrounds the plurality of bearing rollers and the head shaft to retain the plurality of bearing rollers in cooperation with the head shaft.

The invention relates to a carriage of a linear motion guide for arranging on a rail of the linear motion guide, said carriage having an at least substantially U-shaped cross-section and having at least one substantially U-shaped base body (15) which is supplemented with plastic components, wherein the carriage, in both legs of the U-shape, is in each case connected to at least one self-contained rolling body housing (7) which is kept open towards the rail in order to guide as precisely as possible on the rail and nevertheless being easy to assemble. According to the invention, at least parts of inner and outer boundary surfaces of a return channel (10) and both deflection channels (11) of one of the rolling body housings in the respective leg are formed by means of a one-piece plastic component in both legs of the carriage.
