Basic Inspection
Visual Inspection: No deformation of the cylinder body, no scratches/bending of the piston rod, no cracks in the mounting base.
Air Tightness Test: After air supply, check for air leaks in the cylinder body, end caps, and interfaces; check for smooth and unobstructed reciprocating movement of the piston rod.
Maintenance (Recommended and Essential): Clean the piston rod and apply specialized grease to reduce friction and wear.
Replace worn seals and buffer gaskets (Sheffer offers corresponding repair kits) to prevent air leaks and cross-contamination after reassembly.
Inspect the joint bearings of the linkage mechanism, clean and lubricate them to ensure synchronized operation.
