A precision-engineered adjustable stroke cylinder featuring mechanical stroke adjustment screws at both ends for fine position control (±1mm repeatability). The dual cushioning system minimizes impact noise while maintaining 0.5m/s maximum piston speed. Optional magnetic piston version (SAIJ40X25-20-M) available for position sensing.
- Precision workpiece clamping in CNC fixtures
- Variable stroke applications in packaging machinery
- Position-adjustable stops in automated assembly lines
- Material handling systems requiring force control
- Semiconductor equipment with space constraints
Adjustment procedure:
Use 3mm hex key to rotate cushion screws (max 2 full turns). Lock adjustments with counter nut.
Always depressurize before adjustment. For optimal performance, maintain 0.5-1mm oil film on rod surface.
