High-force industrial cylinder designed for heavy-duty automation applications. Features precision-ground rod guides and multi-lip wipers for contamination resistance. The STC variant includes magnetic position sensing capability for feedback systems. Requires 40μm filtered air and recommended lubrication (ISO VG32).
- Material handling systems (palletizers/conveyors)
- Press machine clamping mechanisms
- Plastic injection molding ejectors
- Automotive assembly line positioning
- Steel mill door actuators
Installation note:
Optimal performance achieved when mounted horizontally. Allow 0.5% stroke margin
for thermal expansion. Use flexible couplings for side-load applications.
Magnetic sensor cables should be routed separately from power lines.
