High-precision industrial cylinder featuring corrosion-resistant hard anodized surface (25μm thickness) and magnetic piston for position sensing compatibility. The SI40 series utilizes dual sealing system with wiper ring (DIN 3761A) to prevent particulate ingress. Designed for 5,000km service life at rated load under standard operating conditions.
- Automated assembly line clamping mechanisms
- Plastic injection molding ejector systems
- Packaging machine vertical lift actuators
- CNC machine tool chip conveyor pushers
- Automotive welding fixture positioning
Installation guidelines:
Use M6×25 flange screws (8.8 grade min) with anti-vibration washers.
Maintain 0.5–1mm alignment tolerance during mounting. Lubricate with
ISO VG32 hydraulic oil if operating below 3℃. Avoid side-load exceeding
10% of max thrust capacity.
