The chrome-plated piston rod incorporates dual scrapers for contamination resistance in dusty environments. Integrated cushioning adjustment screws allow precise deceleration control without disassembly.
Common Applications:
- Precision workpiece clamping in CNC fixtures
- Variable height adjustment in packaging conveyors
- Material feeding mechanisms with position feedback systems
- Automated assembly line positioning stations
- Die height compensation in stamping presses
Installation tip:
Maintain 0.5-1mm clearance between stopper and cylinder end cap during adjustment.
Use thread locker (medium strength) on adjustment screws after final positioning.
Stroke Adjustment Procedure:
- Loosen lock nut (M10x1.5) using 17mm wrench
- Rotate stopper sleeve (22mm hex) clockwise to reduce stroke
- Counter-rotate to increase stroke while monitoring position sensor
- Retighten lock nut at 4.5-5.5 N·m torque
