4.3.1. Piston Seal Change Procedure
The collet chuck on the LaserTurn
®
1 is equipped with o-ring piston seals that are designed to last many
collet chuck (open/close) cycles. However, due to regular wear, the seals may require replacement during
the lifetime of the product. If trouble with the piston seals is suspected, it is recommended that you contact
Aerotech Technical Support. The seals should only be replaced by a qualified Aerotech technician.
4.3.2. Ringseal O-Ring Replacement
During the lifetime of the stage, it may be necessary to change the ringseal o-rings. Contact Aerotech to
obtain proper replacement seals. The ringseal screws into the center of the shaft from the front of the stage.
Use the steps that follow to replace the o-ring.
D A N G E R : To minimize the possibility of bodily injury or death, disconnect all electrical
power prior to performing any maintenance or making adjustments to the equipment.
Step 1: Remove power to the stage.
Step 2: Remove collet (See
).
Step 3: With the collet removed, the ringseal will now be exposed. Using a 4 mm allen key or [WIHA Tool
#54040] unscrew the ringseal from the shaft.

Typical Ringseal Removal
Step 4: Remove the o-ring ringseal (shown in
) and replace it with a properly lubricated new item.
The shaft o-ring is a static seal and provides secondary protection against leaks. This seal does not
need to be replaced unless required. Use a long pick or thin screwdriver to remove the shaft o-ring.
Step 5: Wrap the ringseal threads with Teflon thread seal tape [PTFE tape] in preparation for installation.
Step 6: Re-insert the ringseal into the inner collet housing and tighten into position.
Step 7: Re-insert the collet.
