Abstract (en)
[origin: EP0900635A2] Impact tool is operated with reciprocating drive between end stops and is guided by one or more sleeve bearings inside an outer guide (10). Each bearing comprises an inner sleeve (16) which guides the shaft of the tool and an outer sleeve (17) of elastic material which slides inside the guide. The outer sleeve is contoured (17b) on the outside to allow a tilt action of the tool inside the support guide, thus preventing jamming of the tool and prolonging bearing life. The bearing tilts about in either direction about a central plane (18).
