A precision adjustable cylinder with dual-axis angular compensation, designed for applications requiring fine position tuning and shock absorption. Features chromium-plated piston rod (HRC 45-50 hardness) and anodized aluminum barrel for corrosion resistance. The 20° adjustable joint allows ±5° misalignment compensation, making it ideal for non-axial load scenarios.
- Automated packaging line gripper positioning
- CNC machine tool clamping mechanisms
- Glass cutting equipment with variable stroke requirements
- Pharmaceutical tablet press ejection systems
- Automotive welding jig alignment
Installation tip:
When using angular adjustment, limit lateral force to ≤15% of maximum thrust.
For 250mm strokes, recommend adding intermediate support at 120mm intervals.
Lubricate guide shafts every 500km of cumulative travel.
