High-force industrial cylinder designed for heavy-duty automation systems. Features corrosion-resistant construction with double-sealed rod bearing for extended service life. The 125mm bore delivers 9,817N thrust at 0.8MPa (theoretical value). Includes anti-rotation guide for precise linear motion.
Typical Applications:
- Automotive production line clamping fixtures
- Steel plate punching press actuation
- Injection molding machine ejector systems
- Packaging machinery compression units
- Foundry equipment door actuators
Installation guidelines:
- Align cylinder axis within 0.2mm perpendicular tolerance
- Use locknuts with 160-180Nm torque for flange mounting
- Maintain 0.3-1.0mm lubrication oil film on rod surface
- Allow 50mm free space at stroke end for cushion effectiveness
Critical notes:
- Maximum side load capacity: 1,350N at mid-stroke
- Do not exceed 1,200mm/s piston speed without external damping
- Requires 40μm filtered air with ISO 8573-1:2010 Class 4.4.3 quality
- Ambient humidity must remain below 90% RH (non-condensing)
