Precision-adjustable industrial cylinder featuring micrometer-style stroke control (±0.5mm repeatability). The dual-chamber design maintains consistent force output across stroke adjustments. Corrosion-resistant construction with IP54 splash protection enables reliable operation in humid environments. Integrated shock absorption reduces end-impact by 70% compared to standard cylinders.
- Precision workpiece positioning in CNC loading systems
- Variable height clamping in automotive welding jigs
- Adjustable press mechanisms in packaging lines
- Semiconductor handling equipment requiring micro-adjustments
- Textile machinery with variable stroke requirements
Operation tip:
Always depressurize before adjusting stroke length. For fine adjustments,
use the hexagonal wrench to loosen the locknut (torque ≤5N·m), then rotate
the adjustment screw (1 full rotation = 2mm stroke change). Relubricate
every 500km of cumulative travel.
