A guide rail, for use with a guide carriage having at least one row of rolling elements, extends along a longitudinal axis and has at least one running surface for the rolling elements, a separate heat sink, and a plurality of first through holes. The running surface is arranged parallel to the longitudinal axis. The heat sink extends along the longitudinal axis and lies against the guide rail. At least sections of the heat sink delimit a first and a second cooling channel that each extend along the longitudinal axis. The first through holes are distributed along the longitudinal axis and are configured to receive screw-bolts. The heat sink has a plurality of second through holes, each aligning with and continuing an associated first through hole. The first and second cooling channels are located on opposite sides of the plurality of second through holes.

Provided is a damping member which can be easily mounted to a rolling guide device already in use, can avoid an increase in size of the rolling guide device, and can easily enhance a damping force in an axial direction exerted by the rolling guide device. The damping member is applied to the rolling guide device in which a moving block is assembled to a track rail through intermediation of a plurality of rolling elements, is provided to the track rail in series with the moving block, and includes: a friction member which includes a sliding contact pad in contact with at least the track rail; and a fixing holder, which includes a holding portion configured to cover the friction member so as to press the sliding contact pad against the track rail, and is configured to couple the friction member to the moving block.

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.

In an infrared spectrophotometer, a plurality of rolling elements are provided between a movable portion and the holding portion. While no external force is applied from a spring, a play space is generated between the movable portion, the holding portion, and each rolling element. In the infrared spectrophotometer, when the movable mirror and the movable portion are slid, an external force directed downward is applied to the movable portion by the spring, thereby preventing each rolling element from moving between the movable portion and the holding portion. Accordingly, when the movable mirror and the movable portion are slid, it is possible to suppress rattling of the movable portion and the holding portion while leaving a fine gap between the movable portion, the holding portion, and each rolling element. This makes it possible to easily control the moving speeds of the movable mirror and the movable portion and to suppress rattling of the movable mirror and the movable portion.

An anti-rotation system having a replaceable keyway is disclosed, wherein the system comprises a housing having a bore extending along an axis of the housing, and a housing aperture extending from an outside surface of the housing to the bore and extending along the housing parallel to the axis of the housing; a member configured to slide within the bore along the axis of the housing; an insert defining a keyway removably mounted on the housing wherein the keyway extends at least partially into the housing aperture; and a key carried by the member and engaged with the keyway defined by the insert; wherein the key cooperates with the insert to resist rotation of the member about the axis of the housing.
