Industrial-grade adjustable stroke cylinder featuring precision-machined dual locking nuts for mid-stroke positioning. The through-rod design enables external stroke adjustment without disassembly. Integrated shock absorbers reduce end-impact noise to ≤75 dB. Corrosion-resistant construction with IP54 rating for harsh environments.
- Variable height positioning in automated assembly lines
- Clamping force adjustment in CNC fixture systems
- Packaging machine stopper mechanisms
- Material handling with variable lifting heights
- Plastic injection molding ejector systems
Installation tip: Lubricate adjustment threads with ISO VG32 hydraulic oil before initial use.
Locking nuts require 12-15 N·m torque for secure positioning. Avoid side-load forces exceeding 50N.
Maintenance note: Recalibrate stroke every 50,000 cycles. Replace cushion seals
if cushioning effect decreases by >20%. Use only AirTAC AHH-32 lubricator for maintenance.
