Abstract

The invention relates to a chain guide for a chain saw, with a pair of side plates, between which a spindle is arranged in a fixed position, and a chain wheel which is rotatably mounted relative to the spindle. The chain wheel is rotatable about the spindle and serves to direct the saw chain, moving at high speed, around the edge of the guide. Roller bearings are arranged between the spindle and the chain wheel. A pair of annular seals are in each case arranged between the chain wheel and one of the side plates and between the chain wheel and the other side plate. Each of the seals has an annular bead which rebounds at an angle and is in flexible contact with a surface of the chain wheel or one of the side plates. If no lubricant is supplied, a lubricating opening formed in each side plate is closed by a flap on an annular seal or an elastic valve device which is inserted into a central bore of the spindle. When lubricant is supplied under pressure via the opening, the flap or the valve device yields on account of the elasticity and enables the roller bearings to be supplied with grease.
