The invention concerns a linear guide which is of a simple structure and which can be easily fitted, having self-adjusting play reduction. It includes a slider with slide surfaces and a rail with guide surfaces, wherein the slider is guided with its slide surfaces adapted to the guide slide surfaces in slidingly displaceable reciprocating relationship in a displacement direction (v) at the guide surfaces of the rail. The self-adjusting play reduction of the linear guide has at least one adjusting element which according to the invention has a slide surface forming a portion of one of the slide surfaces of the slider.

A device for adjusting the bearing play of components mounted coaxially rotatable to one another and rotatably joined to one another via two axially separated roller bearings is operatively connected to one roller bearing by an end side and to a counter bearing by the opposing end side. The device is formed by two coaxially adjacent rings on one of the components. Each opposing end surface thereof has at least one contour projecting from the plane of the end surfaces. At least one contour has an incline on which the at least one opposing contour slides. One ring is operatively connected to the counter bearing by the other end surface. The other ring is operatively connected to the roller bearing. A device for mutual radial rotation and a device for locking the axially moving ring in the assumed axial position are on both rings.

In a gripping device with carriages movably guided in a common guide groove arranged in a base body so as to be movable in a direction parallel to a gripping direction and supported all around in a direction transverse to the gripping direction, the guide groove includes at least one carriage guide track is supported therein and has opposite surfaces which are in contact with a carriage along a contact junction which is inclined with respect to the vertical longitudinal center plane at an angle of 0.3 to 1.3 degrees.

A wedge bearing assembly includes a housing having a bore therein. A reciprocating rod having a polygonal cross-section extends through the bore. A ring is mounted to the housing and includes a plurality of sloped surfaces adjacent to a center polygonal opening. A plurality of wedges are disposed against a respective one of the plurality of sloped surfaces, each of the plurality of wedges having an edge disposed against the rod. A washer is disposed against the plurality of wedges and an annular spring is disposed against the washer. A tension ring is disposed against the annular spring.

An adjustment system for adjusting the position of at least one sliding block of a movable crosspiece of a press with respect to the respective column of the press on which the sliding block may slide, a first wedge is integral with the movable crosspiece, a second wedge is sliding on the first wedge, a pin defining an axis and having a first eccentric end accommodated in a cavity provided in the second wedge, a first actuating member adapted to rotate the pin causing the translation of the second wedge along a direction transversal to the axis, a second actuating member adapted to translate the pin from a first locked position to a second unlocked position in which the pin can rotate about the axis.

A linear slide rail includes a rail structure and a slider structure. The rail structure has an elongated strip shape and defines a longitudinal axis direction, wherein the rail structure has two guide grooves respectively disposed at two opposite sides of the rail structure. The slider structure has a cooperating groove which is slidably sleeved on the rail structure. The slider structure includes a carrier assembly and two guide wheel seat assemblies. The two guide wheel seat assemblies are respectively disposed at two opposite sides of the carrier assembly, and the two guide wheel seat assemblies are respectively disposed corresponding to the two guide grooves at the two opposite sides of the rail structure. Each of the guide wheel seat assemblies includes a seat unit, a plurality of guide wheel units, a plurality of shaft units, a first lever unit, and a first adjusting unit.

A bearing assembly can comprise: a base member including at least one base ramp; a carriage member including: a first surface defining a bearing channel, the bearing channel configured to receive a plurality of ball bearings and allow recirculating movement of the ball bearings, the bearing channel having a variable depth, wherein the bearing channel having a variable depth is configured to allow the plurality of ball bearings to extend beyond the first surface at a first portion of the bearing channel and extend below the first surface at a second portion of the bearing channel; a second surface opposing the first surface, the second surface including at least one carriage ramp, the carriage ramp configured to engage the at least one base ramp; and a retaining member configured to cover a least a portion of the first surface and retain the ball bearings in the carriage member.
