摘要
The invention relates to a bushing system, particularly adapted for the use in dusty environments, and suitable for journalling pins, shafts and the like, so as to permit them to be rotated but not to be axially displaced, comprising a supporting hollow body, rotatably receiving in the inside thereof the pin, shaft or the like, and two spaced guide bushings, made of plastic material; the two bushings are axially pressed against end collars on said pin, shaft or the like, by means of a helical spring mounted between said bushings, the spring force being selected to be higher than the yield load of the plastic material forming said bushings.
