ABSTRACT:
The linear motion rolling guide unit according to this invention enables the under seals to be mounted to the end caps easily without being deformed as by buckling or without requiring high-precision machining. The under seal is provided, at its longitudinal ends, with locking bands that engage with engagement grooves formed in the end caps. Mounting and dismounting the under seal to and from the end caps are accomplished by expanding the locking bands in the longitudinal direction of the under seal. The under seal is allowed to undergo longitudinal and lateral deformations with respect to the end caps, which deformations caused by external force, thermal expansion and swelling. This construction prevents deformation of the under seal such as caused by buckling and improves the sealing performance.
