High-torque industrial cylinder designed for heavy-duty linear motion applications. Features precision honed tube with 0.01mm inner surface roughness for smooth operation. Integrated magnet slot (optional) enables position sensing compatibility. The chrome-plated piston rod undergoes multi-stage polishing achieving Ra≤0.2μm surface finish, ensuring exceptional wear resistance in contaminated environments.
- Metal stamping press ejection systems
- Automotive welding fixture positioning
- Bulk material handling gates (mining/cement)
- Paper roll clamping mechanisms
- Plastic injection molding machine core pulls
Installation guidelines:1. Use M10 class 8.8 mounting bolts with anti-vibration washers
2. Maintain 0.5mm minimum alignment tolerance during rod connection
3. Apply ISO VG32 hydraulic oil for initial lubrication
4. Install air filter regulator with ≤25μm filtration upstream
Critical notes:• Not suitable for side load applications without guide rail integration
• Maximum lateral rod load: 1,250N at full extension
• Requires monthly lubrication in high-cycle (＞1M cycles/year) operations
