Re-greasing
Procedure for modules without bellows (SM25 and XM38)
Move the forcer to one end.•
Each thrust rod end support has an M10 through •
hole which lines up with the bearing carriage
lubrication nipple. These can be seen in Figure 3.1.
For clarity, the forcer has been removed.
Insert the grease gun delivery tube through the •
M10 hole and engage the nozzle with the bearing
carriage lubrication nipple. The grease gun nozzle
does not attach itself so opposing pressure will
need to be applied to the grease gun and forcer.
Transfer of grease into the bearing carriages is •
achieved by squeezing the grease gun lever 1-2
times. If grease is seen coming out of the bearing
carriages stop squeezing the lever. Over greasing
does not damage the bearings but is not desirable.
Remove the grease gun. •
Note. There is only one bearing carriage on the SM2504 module.
Move the forcer to the opposite end. Repeat the above steps to re-grease the other bearing carriage. •
Move the forcer by hand to and fro in order to distribute the grease.•
Note. If too much grease has been transferred into the bearing carriages the excess should be cleaned away.
If left, it may interfere with the function of an optional encoder where tted.
Procedure for modules with bellows (SB25 and XB38)
To re-grease an SB module, it is necessary rst to remove the bellows.
Refer to ‘Removing the Bellows’ on page 24.•
The lubrication nipple can be seen in Figure 3.2 •
after the bellows have been removed. For clarity,
the forcer has been removed.
Engage the grease gun delivery tube and the •
nozzle with the bearing carriage lubrication nipple.
The grease gun nozzle does not attach itself so
opposing pressure will need to be applied to the
grease gun and forcer.
Transfer of grease into the bearing carriages is •
achieved by squeezing the grease gun lever 1-2
times. If grease is seen coming out of the bearing
