Rollerbearing of concentric rings and fill-hole stopper uses conical stopper of body and washer with interposed seals plus penetrating pin to position stopper body

摘要

The specifically conical stopper (3) consists of releasably joined body (5) and pressure washer (6) with interposed O-ring seal (8) in washer recess and the stopper body is pierced by a conical pin (9) with O-rings (10,11) in its end grooves. The main body (5) of the stopper is positioned by means of a pin penetrating axially beyond the body ring bearings (1,2). Part of the body circumference at the washer end is left free to take a spacer sleeve fitted in this free position with end-mounted O-rings and the sleeve itself is led off at its outward ends taking suitably profiled sealing rings in the free position specified.
