A heavy-duty linear actuator optimized for industrial automation, featuring precision-machined aluminum alloy barrel (A6063-T5) with honed inner surface (Ra≤0.4μm). The chrome-plated piston rod (HRC 45-50) resists side loads up to 10% of maximum thrust. Integrated magnetic sensor slots enable position feedback when used with proximity switches (sensors sold separately).
- Material handling systems requiring long-stroke linear motion
- Automotive assembly line clamping mechanisms
- Packaging machinery for carton ejection
- Plastic injection molding machine core-pulling
- Textile machinery tension control systems
Installation guidelines:
Maintain 0.1-0.3mm alignment tolerance during mounting. For strokes >500mm,
use intermediate rod support brackets to prevent deflection. Lubricate with
ISO VG32 hydraulic oil (1-2 drops/min via air line lubricator recommended).
- Max thrust: 502N @0.6MPa (extending), 447N @0.6MPa (retracting)
- Max speed: 800 mm/s (cushion adjustment required above 500 mm/s)
- Piston speed: 50-700 mm/s (optimal operating range)
- Air consumption: 9.8L/stroke @0.6MPa
