A ball carriage includes a raceway including an engagement segment to urge balls into rolling engagement with an element that is movable relative to the ball carriage. The engagement segment defines an opening through which balls are to engage the element. The raceway includes a return segment including a curved surface to take balls out of engagement with the element. The engagement segment and the return segment share a raceway surface that runs a full length of the raceway to contain balls within the raceway. A ramp is positioned at a transition from the engagement segment to the return segment. The ramp rises from the raceway surface at the opening towards the return segment to guide balls out of engagement with the element and into the return segment.

The rotatable brush includes a plurality of sets of bristles, each extending outwardly from a core. A shaft extends through the core of the brush. The shaft is a telescoping shaft, which is configured to retract and expand to create an elongated brush assembly. An apparatus, system, and method for conveying an assembly along a track. A rail includes a first planar side, a second planar side, and a third planar side. The first, second and third planar sides are arranged to form at least two acute angles ranging between 50 degrees and 80 degrees. A carriage assembly includes a drive wheel and at least two rollers. The drive wheel is configured to contact the second planar side and is configured to translate the assembly along the rail. The two rollers are configured to contact the two other sides to maintain the carriage in contact with the rail.

A machine tool includes: a movably configured saddle; and a bed having a sliding surface supplied with a lubricant and allowing the saddle to slide thereon, and receiving the weight of the saddle. The sliding surface has a recess continuously extending in a direction in which the saddle moves. By this configuration, a machine tool which easily holds a lubricant on a sliding surface and a method for producing a structure for the machine tool having the sliding surface are provided.

A supporting device for a rail member includes a first supporting frame and a second supporting frame. The first supporting frame has a first supporting means including a first supporting part and a second supporting part. A supporting passage is defined by the first supporting part and the second supporting part. The second supporting frame has a second supporting means including a third supporting part and a fourth supporting part. The first supporting means and the second supporting means are configured to support each other. A rail member is configured to be connected to one of the first supporting frame and the second supporting frame, the first supporting part is configured to support the third supporting part, and the second supporting part is configured to support the fourth supporting part. The first supporting part is spaced from and not directly connected to the second supporting part.

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.

A supporting device includes a first supporting frame having a first supporting means including a first and a second supporting part, and a second supporting frame having a second supporting means including a third and a fourth supporting part. A supporting passage is defined by the first and the second supporting part. The first and the second supporting means are to support each other. A rail member is to be connected to one of the first and the second supporting frame. The first and the second supporting part are to support the third and the fourth supporting part, respectively. The first supporting frame further includes a first side wall connected to the first and the second supporting part. The first supporting part has a first portion extended from a first end of the first side wall to form a first angle therebetween. The first angle is a non-right angle.

The application discloses sliding support assemblies which allow for relative linear motion between two bodies. The sliding support assemblies include a rolling slide mechanism and a friction slide mechanism. The rolling slide mechanism provides a low resistance to sliding motion between the two bodies. The friction slide mechanism provides support to the sliding support assembly when the loading between the two bodies is increased.

A press-fitting jig for a closure cap which is configured to press-fit a closure cap into a bolt mounting hole formed in a track rail of a guide device. The press-fitting jig is mounted to a moving block, which is assembled to the track rail through intermediation of a plurality of rolling elements and is configured to move on the track rail. The press-fitting jig includes: a finishing surface which is brought into slide contact with an upper surface of the track rail having the bolt mounting hole opened therein; and a guide surface, which is formed adjacent to the finishing surface and forms a wedge-shaped space with the track rail in a longitudinal direction of the track rail, the guide surface being configured to push the closure cap temporarily placed in the bolt mounting hole into the bolt mounting hole along with movement of the moving block.

A supporting device for a rail member includes a first supporting frame and a second supporting frame. The first supporting frame has a first supporting means including an upper element and a lower element. The upper element includes a first supporting part. The lower element includes a second supporting part. A supporting passage is defined by the upper element and the lower element. The second supporting frame has a second supporting means including a third supporting part, a fourth supporting part and a second side wall extendedly connected to the third supporting part and the fourth supporting part.
