ABSTRACT:
The slide unit includes a rodless power cylinder having a cylinder tube. End caps are attached to both ends of the cylinder tube. A slit extending in parallel with the axis of the cylinder tube is formed on the wall of the cylinder tube. A piston is disposed in the bore of the cylinder tube and is movable along the slit. An external carriage is connected with the piston by a yoke extending through the slit. An inner seal band and an outer seal band extending along the slit for closing the opening of the slit from the inside and outside, respectively, are provided. The ends of the inner seal band and the outer seal band are inserted into corresponding recesses formed on each of the inner end faces of the end caps. A pin hole crossing the recesses and extending to the upper face of each end cap is provided. A fitting hole is disposed on each end of the inner seal band and the outer seal band at the position corresponding to the pin hole. The inner seal band and the outer seal band are secured to each end cap by inserting a fitting pin into the fitting holes at the ends of the seal bands through the pin hole. Since the seal bands are secured to each end cap only by a fitting pin, the assembly of the seal bands is largely simplified.
