Abstract
A circumrotating circulating guiding assembly of a linear sliding rail includes a sliding base body, a plurality of guiding assembly and a plurality of rolling elements. The sliding base body has a plurality of engaging portions and a plurality of guiding holes. The sliding base body is provided longitudinally with engaging portions. The guiding assembly comprises two circumrotating guiding portions, a plurality of fixing portions, a spacer and a plurality of guiding tubes. The fixing piece is fixed to the engaging portion. The guiding portion is combined with the circumrotating guiding portion. The rolling element is provided on the circumrotating circulating path in a rolling manner. With the fixing pieces being fixed to the engaging portion, and the spacer being engaged in the recessed portion, the insufficient strength of the guiding assembly formed of plastic materials can be compensated, thereby avoiding the vibration, noise and excessive frictional resistance efficiently.
