Installation note:
Always install with rod downward in vertical applications to prevent condensate accumulation.
Use locknuts with 30-35 N·m torque for rod-end connections. Maintain 1.5× bore size clearance
for full stroke operation.
Maintenance cycle: Relubricate every 500km stroke distance or 6 months in high-load applications. Replace wiper seals annually when operating in abrasive environments.
