The SI40X80H features precision honed tubing and anodized surfaces for smooth operation in high-cycle applications. Its integrated magnet enables position feedback when used with magnetic sensors (SN-/SM- series). The chrome-plated piston rod incorporates a hard coating layer (20-30μm) for wear resistance. Requires ISO VG32 or equivalent hydraulic oil mist lubrication for optimal performance.
- Automated assembly line clamping mechanisms
- Plastic injection molding ejector systems
- CNC machine tool door interlocks
- Food processing conveyor gate controls
- Automotive welding fixture positioning
Installation tip:
Align cylinder axis within 0.2mm perpendicular tolerance during mounting.
For vertical installations exceeding 45° angle, use guide brackets to prevent
side load. Lubricate every 2,000km of cumulative stroke movement.
