4.3.2. Ringseal O-Ring Replacement

During the lifetime of the stage, it may be necessary to change the ringseal o-rings. A typical ringseal insert
is shown in Figure 4-4. The ringseal screws into the center of the shaft, from the front of the stage and is
replaced by the following steps:
D A N G E R : To minimize the possibility of bodily injury or death, disconnect all electrical power
prior to making any mechanical adjustments.
Step 1: Remove power to the stage.
Step 2: Release the collet. Since the collet holder is in the normally closed position, this will require air pres-
sure supplied to the air inlet.
Step 3: Once the collet has been released, unscrew the collet nut. If necessary, use a spanner wrench avail-
able from Aerotech.
Step 4: With the collet and collet nut removed, the ringseal will now be exposed. Using a tool dimensioned
in Figure 4-5, unscrew the ringseal from the collet sleeve.
Step 5: Remove the o-ring on the ringseal itself, and replace it with a properly lubricated new item. The sec-
ond o-ring is within the collet sleeve (shown in
essary to remove the o-ring and replace it.
Step 6: Re-insert the ringseal into the inner collet housing and tighten it into position.
Step 7: Replace collet and collet nut
