High-precision adjustable stroke cylinder featuring a unique mechanical stopper system for millimeter-level position control. The dual-chamber design allows mid-stroke pressure holding capability. Includes wear-resistant guide bands for reduced metal-to-metal contact.

Typical Applications:

• Precision press mechanisms in PCB assembly
• Variable height positioning in textile machinery
• Clamping force adjustment in automotive jigs
• Material feeding systems with variable stroke requirements
• Packaging machine end-effector positioning

Operation note: For optimal performance, lubricate with ISO VG32 hydraulic oil before initial use. Avoid lateral loads exceeding 15% of maximum thrust. Stroke adjustment should be performed at 0.3MPa or lower pressure.

Critical Notice: The mechanical stopper requires torque limitation (max 2.5N·m) during adjustment. Over-tightening may deform the precision ground rod. Use included adjustment wrench (TX-20H specification) for maintenance.
