High-force industrial cylinder optimized for long-stroke applications, featuring triple sealing rings for leak prevention and chrome-plated precision piston rod with 20μm surface roughness. The hard-coat anodized barrel provides exceptional wear resistance in high-cycle operations (up to 2 million cycles). Requires ISO VG32 hydraulic oil mist lubrication for optimal performance.
- Automated assembly line material handling systems
- Plastic injection molding machine ejectors
- Steel coil lifting/pressing mechanisms
- Automotive welding fixture positioning
- Paper processing equipment tension control
Installation notes:
- Allow 15mm minimum lateral clearance for thermal expansion
- Align within 0.2mm/m perpendicularity tolerance during mounting
- Use flexible couplings for strokes above 500mm to prevent side load
- Pre-charge lubricator with 1-2 drops/sec oil feed rate
