Installation guidelines
When the V-Ring is used as a grease seal/contaminant excluder, the V-Ring is normally mounted on the outside of a bearing housing, with or without, axial support.
General rules:
1. The V-Ring, the counter-face and the shaft should be clean.
2. The shaft should preferably be dry and free from grease or oil, particularly when the V-Ring is mounted without axial support.
3. The lip of the V-Ring should be lubricated with a thin film of grease or silicone oil.
4. In cases when friction must be reduced to a minimum, coat the counter-face with a low friction agent, and do not apply grease to the lip.
5. Ensure that the V-Ring is mounted with a uniform stretch around the shaft.
When the V-Ring is mounted on the shaft the outer diameter of the lip is reduced. Unless the stretch is uniform this reduction will vary around the periphery. This may lead to partial entry of the lip in the bore of the counter-face when the seal is pushed into position.
In the case of large diameter seals a uniform stretch can be achieved by inserting a blunt screwdriver or a piece of string under the V-Ring body and running it around the shaft twice. Take care not to damage seal or shaft.
The most convenient method of assembling large diameter V-Ring's, to ensure uniform stretch, is to mark off the body of the V-Ring and the shaft or seating with six equidistant marks. The marks should then be matched together when the V-Ring is fitted in position.
