Paired mounting
If two radial shaft seals are to be mounted in a
common housing bore either in tandem or in a
back-to-back arrangement, care must be
taken to see that neither of the sealing lips can
run dry at any time. To eliminate any risk of
dry running, the free space between the seals
or sealing lips should be filled with a suitable
lubricating grease.
To guarantee lubricant supply to the sealing
lips in operation and to prevent dry running,
the use of a spacing ring between the two
seals is recommended. This ring should be
provided with lubrication holes (fig 61), so that
grease can be supplied to the space between
the sealing lips, e.g. via a grease nipple. No
spacer ring is required when using HDS3 seals
as these have spacer lugs built into the large
side face (fig 62).
