Removing the bearing and end caps
Caution
The compression spring of the AEN compact cylinder is pretensioned; during
dismantling the bearing or end cap can be spun off and cause injuries.
A suitable support device can be used to prevent the bearing or end cap
from being spun off.
1. Mount the support device.
2.
Unscrew the flange screws or socket head screws (AEN-80 / 100 only) from
the bearing cap and end cap.
3. Dismantle the support device carefully and at the same time pull the
bearing and end caps from the cylinder barrel and the piston rod.
4. Clean the threads of the screws to remove any locking agent residue.
7.3
Replacing the piston components
1. Pull the piston rod out of the cylinder barrel.
2. Inspect the cylinder barrel and piston rod for damage.
The entire cylinder must be replaced if the cylinder barrel (particularly the
bearing surface) shows signs of significant damage.
