Seal structure-carrying linear motion rolling guide unit

摘要

This linear motion rolling guide unit is provided with a seal structure(5) capable of being applied to an existing linear motion rolling guide unit without changing the basic specifications thereof. A positioning pin-carrying mounting plate(7) is fixed to a slider(2). Each of seal members(6) incorporated in the seal structure comprises an upper seal portion(17) and side seal portions(18). The positioning pins(9) provided on the mounting plate(7) are inserted into positioning pin holes(19) of the seal members(6), whereby the seal members(6) are positioned, the seal members(6) being then fixed to the mounting plate(7) by fixing screws inserted thereinto from the outer side of a scraper plate(8) provided in contact with the seal members(6). The seal members(6) of the seal structure(5) are renewed by removing the same by outstretching the side seal portions(18) thereof around the central parts of the upper seal portions(17) thereof, and installing new seal members(6).
