A heavy-duty industrial cylinder designed for high-force linear motion applications. Features precision honed tubing with wear-resistant surface treatment (Ra ≤0.2μm) and triple sealing system (rod seal, piston seal, wiper). The dual adjustable air cushions minimize end-impact noise (≤70dB at 0.5MPa). Compatible with all major brand pneumatic systems through ISO-standard porting.
- Automotive assembly line clamping/pressing mechanisms
- Injection molding machine ejector systems
- Steel mill material handling gates
- Food processing conveyor diverters (food-grade version available)
- Palletizing robot end-effector actuators
Installation notes:
- Maintain 0.5mm minimum clearance between rod end and load during alignment
- Use locknuts (DIN 980) with 35-45 N·m torque for mounting
- Lubricate through air port with ISO VG32 pneumatic oil if using non-lubricated air
- For vertical mounting, specify double-acting type with counterbalance valve
