- Textile machinery tension control
Installation tip:
Align cylinder axis within 0.2mm perpendicularity tolerance during mounting.
For vertical installations, add a mechanical lock nut on the rod end to prevent
unintended retraction during pressure loss. Allow 50mm clearance behind rod end
for maintenance access.
