The SI40AX800S medium-duty cylinder features precision honed tubing and dual cushion adjustment screws for controlled deceleration. With 0.5mm rod runout tolerance and 0.2mm/100mm straightness accuracy, it delivers exceptional positional repeatability. The double-sealed piston design minimizes internal leakage (<2 NL/min at 0.5MPa).
- Palletizing robot end-effector actuators
- CNC machine tool clamping mechanisms
- Automated conveyor diverters
- Plastic injection molding ejectors
- Textile machinery tension control
Installation Protocol:
Maintain 0.05mm/m alignment tolerance between rod and load. For vertical mounting,
use counterbalance valves. Lubricate rod with ISO VG32 hydraulic oil if operating
below -10℃. Adjust cushion needles to 1/4 turn from full close position during commissioning.
