ABSTRACT:
The linear motion rolling guide unit has sealing devices that can be applied without having to modify the fundamental specifications of the existing unit and which can also be installed and removed easily. Each of the seals in the sealing device comprises a metal plate core and a rubber bonded to the core by baking. The core has at the central part a notched portion that allows a pair of seal side portions to be opened or expanded. Replacement of the seals can be done simply by fitting new seals over the track rail from above. The interference of the seals in the assembled sealing device can be adjusted easily by adjusting the distance that the adjust screws, whose front ends contact the side surface of the core, are screwed in.
