- Packaging line product ejection mechanisms
- Material handling equipment with adjustable lift heights
- Automotive assembly tooling positioners
- Textile machinery tension control systems
Installation note:
Lubricate through air port (ISO VG32 recommended) before initial use.
Maintain 0.5mm minimum clearance between cushion nut and cylinder
end during stroke adjustment. Avoid side load exceeding 120N.
Critical parameters:
Maximum piston speed 500mm/s (with cushioning). Minimum operating
pressure 0.15MPa for stable stroke adjustment. Annual seal inspection
required under continuous duty cycles.
