High-precision industrial cylinder featuring micro-adjustment capability (±2mm stroke adjustment) through its unique mechanical locking mechanism. The double-sealed piston design ensures leak-free operation even under continuous high-cycle applications (up to 3 million cycles at 0.5MPa). Includes wear-resistant guide bands for smooth linear motion.
- Precision press-fit operations in automotive assembly
- Variable height positioning in CNC material handling
- Adjustable clamping systems for injection molding
- Packaging line product height compensation
- Semiconductor wafer handling automation
Installation guidance:
Use M8×1.25 mounting bolts (torque 12-15N·m). Lubricate with ISO VG32 hydraulic oil
during initial installation. Maintain minimum 30mm clearance behind rod end for
full stroke adjustment. Avoid side loads exceeding 30N.
