An alignment system for a workpiece printing machine comprises a stencil support and a workpiece support, and a planarity control mechanism having at least two actuators arranged to effect relative rotation of the stencil support and workpiece support about both the horizontal axes.

A rolling structure and a method of mounting the same on an object are introduced. The rolling structure includes a body portion, a first rolling member and at least one second rolling member. The body portion is disposed at an object. The first rolling member is movably disposed at the body portion and adapted to roll in the first direction. The second rolling member is movably disposed at the body portion and adapted to roll in the second direction. Therefore, the rolling structure is structurally simple, easy to use, and mechanically strong so as to cut cost.

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 rheometer has rotary rheometer and a linear DM(T)A analysis unit. A measuring shaft of the rotary rheometer carries a measuring part that faces a measuring part carried on an adjusting rod of the linear analysis unit. The sample under test is placed in a measuring gap between the measuring parts. The DM(T)A analysis unit has a linear motor, in particular magnetically operated, with a stator and a slider, and a magnetically-operated gravitational compensation unit, by way of which it is possible to compensate for the weight force of the adjusting rod, the measuring part on the adjusting rod, the slider, and any optional the components fastened to the slider.

An axially compliant rolling bearing for precision motion stages having a stage, at least one bearing member slidably disposed along a rail, and a compliant joint interconnecting the at least one roller bearing to the stage. The compliant joint is sufficiently compliant to permit movement of the stage in the axial direction while remaining stiff in other directions orthogonal to the axial direction.

A steering device according to an aspect of the present invention includes an outer shaft, an inner shaft, an outer column, and an inner column. The inner shaft has a sliding portion configured to be capable of being inserted into the outer shaft, and a bearing-mounting portion that is connected to the sliding portion in an axial direction thereof and is configured not to be capable of being inserted into the outer shaft. In the bearing-mounting portion, rear bearings are disposed with an interval therebetween in the axial direction.

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 door roller mechanism for cooperation with a roller track including a carriage member having a door attachment feature; at least one roller disposed for rotation on a first side of the carriage member when the carriage member moves in the rolling direction; at least one roller disposed for rotation on an opposite second side of the carriage member when the carriage member moves in the rolling direction; a first rub member disposed on the first side of the carriage; a second rub member disposed on the second side of the carriage; and at least one biasing element disposed on the carriage member for resiliently biasing the first rub member and the second rub member in opposite lateral directions so as to contact a respective first track surface and a second track surface in a manner to dampen lateral vibration of a door connected to the roller mechanism.

A door track assembly for cooperation with a door roller mechanism, including a housing having a longitudinal channel along a length of the housing, wherein the channel descends at an end of the housing to form a stowage recess for the door roller mechanism, and a first track and a second track that are disposed on the housing along a length of the channel and that descend into the stowage recess and along which the door roller mechanism traverses.

A carriage for a linear guide system. The linear guide system includes a rail member including two running surfaces facing each other, and the carriage movable relative to the rail member in and against a pull-out direction. The carriage has a base body, a first pair of support elements and a second pair of support elements in the form of sliders and at least one first support spring element and at least one second support spring element. The second pair support elements is arranged spaced apart from the first pair of support element in the pull-out direction. Thereby, each of the sliders of the first pair of support elements and each of the support elements of the second pair of support elements is movably mounted on the base body in an upward direction perpendicular to the pull-out direction, such that each of the sliders is frictionally engageable with a respective one of the running surfaces. The at least one first support spring element is mounted on the base body such that the at least one first support spring element biases the sliders of the first pair of support elements away from each other in the upward direction. The at least one second support spring element is mounted on the base body such that the at least one second support spring element biases the support elements of the second pair of support elements away from each other in the upward direction.
