The SI80AX550S industrial cylinder combines high thrust capacity with precision control, featuring an optimized flow path design that achieves ≤0.15 m/s standard piston speed. Its double-rod design minimizes lateral load deflection, with wear-resistant guide rings providing ≤0.5mm radial play during full extension. The cylinder is pre-lubricated with ISO VG32 hydraulic oil and supports 5 million cycle durability under rated pressure.
- Plastic injection molding machine ejectors
- Automotive welding fixture positioning
- Heavy-duty conveyor gate actuators
- Paper processing equipment tension control
- Foundry machine core-pulling mechanisms
Installation tip:
For vertical mounting applications exceeding 45° angle, install an external guide mechanism.
Maintain 0.5-1mm alignment tolerance during flange mounting to prevent rod scoring.
