In an assembly having a first member moving relatively to a second member, a space exists between the members; and the second member is coated with a synthetic plastics material so as to fill up said space and also to reduce the friction between the engaging surfaces. In a method of applying the synthetic plastics material to the required surface, the members are axially and radially aligned so that the space therebetween is uniform and the synthetic plastics material is injected into said space; one surface having been pretreated so that the synthetic plastics material cannot adhere thereto. The synthetic plastics material may be epoxy resin, graphite and catalyst. A suitable material for protecting the mating surface with the greater dimensional accuracy, is polytetrafluoroethylene or a silicone which may be applied by a spraying or dipping operation, followed by heating to cure the coating. |
