A high-efficiency industrial cylinder featuring dual anti-rotation design and precision honed tube. The SI63BX70 delivers 310N thrust at 0.5MPa with minimal stick-slip effect, making it ideal for repetitive positioning tasks. Integrated magnet slot allows for sensor mounting (inductive type recommended). Requires ISO VG32 hydraulic oil lubrication if used in high-cycle applications (>1 million cycles).
- Automated assembly line clamping mechanisms
- CNC machine tool door interlocks
- Plastic injection molding ejector systems
- Printing press paper feed units
- Automotive welding fixture positioning
Installation tip:
Maintain 0.5mm minimum clearance between rod end and load during alignment.
For vertical mounting, use locknut (M16) to prevent piston rod rotation.
Lubricate through air supply (ISO VG32 mist) for optimal seal life.
