High-torque industrial cylinder designed for heavy-duty cycles (up to 5 million cycles at rated load). Features corrosion-resistant construction with integrated mounting slots for flexible installation. Includes magnetic piston for position sensing compatibility (sensor not included). Requires 40μm filtered lubricated air (ISO 8573-1:2010 class 4.4.3).
- Automated assembly line clamping mechanisms
- Die-casting machine ejection systems
- Plastic injection molding machine core pulls
- Automotive welding fixture positioning
- Packaging machine product pressing stations
Installation note:
Maintain ≤0.1mm/m alignment tolerance during mounting. Use flexible couplings when lateral forces exceed 5% of axial load. Lubricate rod weekly with ISO VG32 hydraulic oil in non-lubricated systems.
