ABSTRACT:
The linear motion rolling guide unit allows the under seal for sealing the circulating passage for the rolling elements to be mounted to the end caps by simply engaging it with the end caps. The linear motion rolling guide unit also has the function of adjusting the under seal as it wears out. The under seal has a lip portion engaging with the underside of the casing and the end caps and a lip portion engaging with the side wall surface of the track rail. Locking portions are formed at longitudinal ends of the core member of the under seal, and insertion grooves are formed in the end caps attached to the ends of the casing. Mounting the under seal to the end caps can be accomplished simply by inserting the locking portions into the insertion grooves.
