Flanged locking slide units FM.R of die-cast aluminum have a split slide unit bore machined by cutting methods. This is arranged in the plane parallel to the face of the flange.
Together with the guide tube, the slide unit bore forms a solid square guide mechanism that can be adjusted and clamped for low play. With the indexing plungers or spring plungers in the top part, it is possible to repeatedly move quickly and easily to positions along a square construction tube defined by bores.
Depending on the design, the part to be moved is fastened to the slide unit or the slide unit itself is installed at the place of use such that the entire locking unit moves together. At the screw points, hex socket cap screws or adjustable hand levers reduce the slide unit bore size.
Adjustable hand levers are intended for repeated, tool-free clamping. Under the designation HSK, these are available separately for individual use and in other designs. Compared with the tool-operated hex socket cap screw, the clamping force achievable with an adjustable hand lever is lower due to the shorter lever length.
