High-force industrial cylinder designed for heavy-duty automation applications. Features precision-machined guide bearings for minimal lateral play (±0.5mm max deviation). The double-acting design with magnetic piston enables position feedback when used with sensors (not included). Optimized air consumption through low-friction seals (≤0.15MPa breakaway pressure).
- Press machine ejection systems (200-500kN force range)
- Automotive welding fixture clamping
- Palletizing robot end-effectors
- Steel mill conveyor gate control
- Plastic injection molding machine core pulling
Installation protocol:
Maintain ≤0.5mm/m alignment tolerance during mounting. Use flexible couplings
for rod connections. For vertical mounting, install speed controller at lower port
to prevent free-fall. Requires 40μm filtration with automatic drain.
