When installing seals on stepped shafts where
the shoulders do not have the recommended
chamfer or rounded transition, a mounting
sleeve as shown in fig 53 must be used. If the
sealing lip has to pass over grooves, threads or
gearing, thin-walled mounting sleeves of the
type shown in fig 54 can be used to prevent
the lip from being damaged. The outside
surface of the sleeve should be coated with the
same lubricant as the seal and counter
surface.
Radial shaft seals made of silicone rubber
should always be installed using a mounting
sleeve.
When a seal is to be mounted at a certain
distance in a cylindrical opening in a housing,
the tools should be according to fig 55 and
fig 56. The dimensions needed for designing
the tools can be supplied on request.
