The first and second walls and the track base define a first channel. The first wall has a first race and the second wall has a second race. The roller support is within the first channel. The roller support has first and second side walls and a center section disposed between the first and second side walls. The first and second side walls are disposed adjacent the first and second walls. The center section is disposed adjacent the track base. The first and second side walls have bearing apertures. The center section has roller openings. The ball bearings are disposed the first and second races. The roll pins are in the roller openings in rolling contact with the track base.

The present invention relates to a guide device for a machine tool comprising a base body having at least one contact surface, a guide rail having at least one bearing surface and a guide axis, and a plurality of exchangeable support plates for positioning the guide rail on the base body.

A linear motion guide unit includes a rail having a raceway groove extending on each longitudinal side surface, and a slider fitting over the rail and movable relative to the rail. The rail includes a first rail member and a second rail member connected to each other in a longitudinal direction at a connecting portion. The first rail member has, at least at one end, a protrusion extending in the longitudinal direction. The second rail member has, at least at one end, a notch to be combined with the protrusion. In the connecting portion, the protrusion of the first rail member is combined with the notch of the second rail member to connect the first rail member and the second rail member. The protrusion and the notch are fixed with a columnar member extending in a direction intersecting the longitudinal direction.

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.

Linear motion mechanism sealants capable of operating at low torque when engaging in linear motion which are capable of carrying out sealing with respect to fine particulate several μm in diameter, and which are side seal units for sealing gaps at a shaft provided at a front end portion and a back end portion of a slider of a linear motion mechanism equipped with said shaft and said slider which carries out reciprocating linear motion on said shaft, the linear motion mechanism side seal units 4 being characterized in that fibrous surfaces of seal members comprising fibrous material are arranged so as to be directed toward said shaft in such fashion as to abut and conform to the cross-sectional shape of said shaft at the front end portion and the back end portion of the slider.

A linear motion guide unit includes a rail having a raceway groove extending on each longitudinal side surface, and a slider fitting over the rail and movable relative to the rail. The rail includes a first rail member and a second rail member connected to each other in a longitudinal direction at a connecting portion. The first rail member has, at least at one end, a protrusion extending in the longitudinal direction. The second rail member has, at least at one end, a notch to be combined with the protrusion. In the connecting portion, the protrusion of the first rail member is combined with the notch of the second rail member to connect the first rail member and the second rail member. The protrusion and the notch are fixed with a columnar member extending in a direction intersecting the longitudinal direction.

A hydrostatic/hydrodynamic fluid bearing assembly for a can bodymaker is provided. The hydrostatic/hydrodynamic fluid bearing assembly is separate from the ram body. The outboard guide bearing assembly includes a carriage assembly and a number of elongated journals. The carriage assembly includes a ram coupling, a crank coupling, and body defining a number of journal passages. The ram body is coupled to a ram coupling. The crank coupling is structured to be coupled to a crank arm. Each journal extends through a carriage assembly body journal passage. In this configuration, the ram body may form a can body in a traditional manner, but fluid bearing assembly fluid is not applied to the ram body. Instead, the fluid bearing assembly fluid is applied to the journals.

An actuator apparatus includes an actuator rod with an interior cavity and a set of rod holes. Each rod hole extends through the actuator rod to the cavity. The set of rod holes is positioned in a straight line. The apparatus includes a light assembly that is positioned to light the cavity. The apparatus includes an actuator block that includes an opening extending through the actuator block sized to conform to an outer surface of the actuator rod and a set of block holes in the opening. Spacing between the block holes matches spacing between the rod holes. The actuator block includes a light sensor positioned in a block hole to sense light coming through a rod hole aligned with the block hole and a ball bearing for each block hole of the set of block holes without a light sensor and extending partially through the corresponding block hole.

A guide device for a machine tool including a base body having at least one contact surface, a guide rail having at least one bearing surface and a guide axis, and a plurality of exchangeable support plates for positioning the guide rail on the base body.

A method includes producing a preform of a guide rail from steel, putting the preform in a holding device so that the preform is held fixed in position, analyzing the preform held in the holding device, a deviation from a straight shape being measured at a plurality of locations along the longitudinal axis. The method further includes irradiating the preform held in the holding device with a laser beam, a surface section being irradiated with the laser beam along the longitudinal axis at a plurality of locations, respectively on one of two side surfaces facing in opposite directions in relation to the first transverse axis, in such a way that it is heated into the plastic range.
