High-precision industrial cylinder featuring micro-stroke adjustability (±1mm accuracy) through external stroke adjustment screws. The double cushioning mechanism minimizes end-impact noise while maintaining positioning repeatability within 0.2mm. Corrosion-resistant construction with ISO-standard mounting interfaces enables seamless integration with automated systems.
- Precision clamping fixtures in CNC machining centers
- Variable position stops in conveyor systems
- Packaging machine pusher mechanisms
- Automated assembly line positioning units
- Printing press paper feed adjustments
Installation note:
Maintain alignment within 0.1mm/m during mounting. For adjustable stroke operation,
loosen locknut and rotate adjustment screw (clockwise for shorter stroke). Relubricate
every 5 million cycles using ISO VG32 hydraulic oil. Avoid side load exceeding 15% of
maximum thrust capacity.
