High-torque industrial cylinder with precision-ground rod and multi-layered sealing system. Features wear-resistant guide bushings and corrosion-resistant coatings, designed for heavy-duty cycling (up to 5 million cycles at rated load). Requires filtered lubricated air (ISO 8573-1:2010 Class 3.4.2) with 1-5 cSt oil viscosity.
- Automotive press line material handling
- Foundry equipment actuation
- Plastic injection molding ejectors
- Heavy-duty clamping fixtures
- Paper mill roller positioning
Installation note:
Maintain 0.1-0.3 mm alignment tolerance during mounting.
For vertical installations, use rod-down orientation with flow control valves
to prevent free-fall motion. Lubricate through air supply (ISO VG32 recommended)
during initial 50,000 cycles.
