High-performance industrial cylinder designed for heavy-duty applications requiring precision linear motion. Features triple sealing system (rod seal, buffer seal, and wiper seal) for extended service life. The chrome-plated piston rod incorporates a hardened layer (0.02-0.05mm) for wear resistance. Optional rod lock mechanism available for vertical applications.
- Automotive production line clamping/positioning
- Steel mill material handling systems
- Plastic injection molding machine ejectors
- Paper processing equipment actuators
- Heavy-duty press brake tooling adjustment
Installation Guidelines:
Maintain 0.5mm minimum alignment tolerance during mounting. Lubricate with ISO VG32 hydraulic oil
(1-2 drops per 1,000 cycles). Adjust cushion screws clockwise to increase damping force. Magnetic
sensor cables must maintain 50mm clearance from power lines.
Critical Parameters:
Maximum piston speed 500mm/s (19.7"/s). Minimum operating pressure 0.15MPa (21.7PSI) for stable motion.
Rod end play ≤0.8mm. Requires 5μm filtration for compressed air.
