4.3. Seal Replacement
4.3.1. Piston Seal Change Procedure
The collet chuck on the ASR1200 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 life-
time of the product. If trouble with the piston seals is suspected, it is recommended that you contact Aero-
tech customer service. 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. A typical ringseal insert is
shown in Figure 4-2. Depending on the size, the ringseal may be one or two pieces. The ringseal screws into
the center of the shaft, from the front of the stage and is replaced by the following steps.
To minimize the possibility of bodily injury, confirm that all electrical power is disconnected
prior to making any mechanical adjustments.
