The seal carrier has three holes in it. Two of these holes are setup for 1/4”
UNC bolts, to aid in removal of the seal carrier. These are directly across
from each other.
The other hole is threaded for 1/8” NPT pipe fitting. One is closer to the
shaft and has a grease zerk installed.This is setup to grease the bearing
and to purge the bearing grease out through the purgeable contact seal
and the taconite seal.
The seal is normally mounted so that the grease fittings are under and
protected by the shaft.
For best purging action, it is recommended to install remote grease lines to
safely regrease bearings while pulley is rotating.
DO NOT regrease SSP bearings with factory installed grease fittings
while pulley is rotating.
Grease using the roller bearing fitting until purging around the seal
carrier is noticed.
The following optional method for regreasing of the SSP may be used.
Using the chart to the right, the SSP is greased with the volume of
grease listed. This will purge all of the old grease out of the bearing,
replacing it with fresh grease. The old grease is purged out through
the two v-ring contact seals and is purged out through the seal carrier.
Section 3 - Maintenance
The first step in removal of the bearing from a SSP is to clean the exterior
surface of the shaft and other surfaces that might contaminate the bearing
housing and interfere with removal of the unit. Loosen or remove the
locking bolts on the mounting block and remove the mounting block from
the shaft.
There are several different types of mounting blocks, but all are
straightforward on removal and are not covered here. If your block has
a single locking bolt, you may need to drive a screwdriver in the split; to
spread the clamp apart and release its hold on the shaft.
Start by loosening the setscrews that hold the seal carrier to the shaft.
There are several ways to remove the seal carrier. The first method is to
remove the plugs in the removal holes and thread in a
1/4” UNC bolt. This bolt is used to grab and wiggle the seal back and
forth to slide the seal carrier off the shaft.
While this works well for most cases, there are alternatives. One is to use
two large screwdrivers and insert them in between the seal
carrier and housing to pry the seal carrier out and off the shaft.
Another alternative is for a split block or one that has the removal holes. In
this case, the mounting block would still be on the shaft or slid back into
place up against the journal. Step 1 will be to cut a piece of threaded rod
equal to the distance between the seal carrier and mounting block, plus
the thickness of the mounting block and one inch. The threaded rod is to
be inserted in the removal holes, which are level with the shaft centerline,
and into the threaded holes in the seal carrier. Install a 1/4” flat washer,
