The present disclosure describes bearing assemblies for a mover of a linear motor system. The bearing assemblies may include a plurality of bearings, a housing that retains the bearings, a plurality of springs biasing at least one of the plurality of bearings towards a track of the linear motor system, and at least one dampening element dampening movement of one or more of the plurality of springs.

One or more embodiments of the present disclosure are directed to a transmission mechanism. The transmission mechanism may include a guiding rail, and a slider movably disposed on the guiding rail, wherein the slider may be provided with a rolling part, the rolling part may roll with respect to the guiding rail, and limit the slider in a first direction and a second direction of the guiding rail, and the first direction and the second direction may both be perpendicular to a length direction of the guiding rail, and an angle between the first direction and the second direction may be greater than 0° and less than 180°.

A support structure includes: a support frame as a shaft support member for supporting two shafts; a bush provided on each of the two shafts in a slidable manner; a cover support member connected to the multiple bushes and configured to support the cover; a first connection member for connecting one end of each of the two shafts to the support frame in a manner that the relative position between the shaft and the support frame will not change; and a second connection member for connecting the other end of each of the two shafts to the support frame in a manner that the relative position between the shaft and the support frame can change.

A slide assembly includes a channel member including a stop recess having a front end and a rear end; a slide member including a sliding first portion, a sliding second portion, a slot, and a connection portion on the sliding first portion, the slide member being configured to move in the channel member; and a release mechanism disposed on the slide member and including first and second release member. In a locked state the first limit members of the positioning portion of the first release member engage with the front larger hole of the stop recess, the second limit members of the positioning portion of the first release member engage with the rear smaller hole of the stop recess, and the elastic arm of the second release member engages with the rear smaller hole of the stop recess. A double release mechanism is provided.

A ball spline with detour tracks includes spline shaft, nut part movable along a longitudinal direction of the spline shaft, and balls between the nut part and the spline shaft, wherein the nut part includes nut adapted to insert the spline shaft thereinto and retainers on longitudinal sides of the nut, the spline shaft includes tracks extended along the longitudinal direction, the nut includes load track grooves formed in longitudinal direction on inner peripheral surface into which the spline shaft is inserted and non-load circulating portions formed in the longitudinal direction, each retainer includes circulating grooves on the inner peripheral surface to face the load track groove and non-load circulating portion, the balls run between the tracks and the load track grooves, and each track includes track groove formed in longitudinal direction of the spline shaft and detour tracks whose longitudinal sides are connected to the track groove.

An end cap for a carriage of a linear guide. The end cap has a closed lubrication port which is openable by operatively connecting a lubrication fitting to the lubrication port. The is formed by injection molding and the closed lubrication port of the end cap is formed by rotary demolding.

An assembly having an outer component, an inner component, and a ring positioned between the outer component and the inner component, where the ring has at least one radially extending projection adapted to seat within at least one groove in the inner component or outer component, and where the projection is adapted to compress radially to allow rotational or axial movement between the inner component and the outer component upon application of rotational or axial force respectively to at least one of the inner component or the outer component.

The present invention relates to a ball spline having a reinforcement bush part, comprising: a rod-shaped spline shaft having at least one concave track groove formed to extend along the longitudinal direction thereof; a nut part in which the spline shaft is inserted and movable along the longitudinal direction thereof; and a plurality of balls provided between the nut part and the spline shaft to circulate, wherein: the nut part includes a nut which is a hollow body into which the spline shaft is inserted, and retainers which are hollow bodies which are provided at longitudinally opposite sides of the nut and into which the spline shaft is inserted; at least one spline part and at least one reinforcement bush part are provided at the nut part; some of the balls change direction in spline circulation grooves of longitudinally opposite side retainers and circulate and move between a track groove and a load track groove and along a no-load circulation part; and the others of the balls roll while being in contact with the outer surface of the spline shaft, and circulate and move along the reinforcement bush part.

Provided is a sliding guide device for a machine tool, which is capable of supplying an appropriate amount of lubricating oil onto a sliding surface in a stable manner for a long period of time. A movable body is provided with a porous-body accommodation space that is open toward a guide face of a base. The porous-body accommodation space is in communication with a lubricating-oil supply passage that is in communication with an external lubricating oil supply unit. In the porous-body accommodation space, a porous body is disposed in a manner to provide a gap G between the porous body and the guide face of the base.
