A heavy-duty industrial cylinder designed for high-force linear motion applications. Features precision honed tubing with mirror-class inner surface finish (Ra≤0.2μm) for minimal friction. The corrosion-resistant design includes IP65-equivalent protection when used with optional wiper seals. Requires ISO 8573-1:2010 Class 3-4-3 compressed air.
- Automotive press line material handling
- Steel mill rolling equipment positioning
- Plastic injection molding machine ejectors
- Heavy conveyor gate actuators
- Industrial lifting platforms
Installation guidelines:
- Allow 0.5mm thermal expansion clearance per meter during alignment
- Use Cushion Needle Valve (QEV-02) for precise speed control
- Lubricate with ISO VG32 turbine oil if non-lube operation required
Critical notes:
- Maximum side load: ≤15% of dynamic thrust capacity
- Minimum 40μm filtration required for extended seal life
- Strictly avoid angular misalignment exceeding 0.5°
