Heavy-duty adjustable stroke cylinder with precision positioning capability. Features dual air cushioning with micrometer-style adjustment screws (±2mm fine tuning) for smooth end-of-stroke deceleration. The anodized barrel resists corrosion in humid environments, while the chrome-plated piston rod includes a wiper seal for contamination protection.
- Variable position clamping in CNC machining fixtures
- Packaging line product height adjustment mechanisms
- Die casting machine ejector systems
- Automated warehouse stacker positioning
- Plastic injection molding machine core-pull actuators
Installation Note:
Maintain 0.5mm alignment tolerance during mounting. Lubricate with ISO VG32 hydraulic oil
if operating below 1 m/s. Cushion adjustment requires pressure gauges on both ports -
turn clockwise to increase damping force. Annual seal replacement recommended in high-cycle
(＞1 million strokes/year) applications.
