High-precision industrial cylinder featuring wear-resistant chromium-plated piston rod and precision honed tube. Equipped with magnetic piston for position sensing compatibility (sensor not included). The SAI63 series offers 20% higher load capacity than standard ISO 6432 cylinders through optimized seal geometry.
- Automated material handling systems
- Plastic injection molding machine ejectors
- Automotive assembly line clamping units
- Packaging machine pusher mechanisms
- Textile machinery tension control
1. Use with clean dry air (40μm filtration recommended)
2. Lubricate with ISO VG32 hydraulic oil for extended seal life
3. Allow 15mm clearance around cylinder for heat dissipation
4. For vertical mounting, orient rod end downward to prevent piston drift
Maximum side load capacity: 120N at mid-stroke
Allowable eccentricity: ≤0.5mm
Lubrication interval: 2,000km travel distance or 6 months
