Precision-engineered adjustable stroke cylinder featuring a visible stroke adjustment scale (1mm graduations) and dual locking nuts for position retention. The enhanced rod bearing design ensures smooth operation at speeds up to 1.5m/s. Includes integrated magnet for position sensing compatibility.

Ideal Applications:

• Variable position clamping fixtures in CNC machining centers
• Adjustable ejector mechanisms in injection molding machines
• Height-adjustable conveyor stops in packaging lines
• Precision paper cutting positioners in printing equipment
• Modular assembly systems requiring frequent stroke changes

Operational guidance: Lubricate with ISO VG32 hydraulic oil before initial use. For optimal cushioning performance, adjust the buffer screws while the cylinder is at 50-70% of maximum operating pressure. Regular maintenance interval: 2 million cycles or 12 months.

Critical note: Avoid side loads exceeding 15N. When used in vertical orientation, always install an air pressure holding valve to prevent unintended movement during pneumatic supply fluctuations.
