The SI63X660S heavy-duty industrial cylinder features extended stroke capability with precision honed tubing for smooth operation. Its double-lip rod seal design reduces leakage risk during high-cycle operations. The hardened piston rod withstands side load conditions common in material handling applications. Includes wear-resistant guide bands for minimum breakaway pressure (≤0.08MPa).
- Automotive assembly line clamping fixtures
- Plastic injection molding machine ejectors
- Steel coil handling systems
- Paper converting equipment actuators
- Construction machinery hydraulic assist systems
Installation requirements:
Maintain 0.05mm/m alignment tolerance during mounting. Lubricate via ISO VG32 hydraulic oil
for initial operation. Use rigid piping supports for strokes >500mm. Allow 15mm clearance
behind rod end for maintenance access.
Critical note:
Not suitable for vertical downward thrust applications exceeding 45° angle without
external guide mechanisms. Requires 40μm filtration for compressed air supply.
