High-thrust industrial cylinder designed for heavy-duty applications requiring precise linear motion. Features enhanced side load capacity with integrated guide bushings and multi-layered sealing system. The corrosion-resistant construction withstands particulate environments (IP65 equivalent when installed with optional protective covers). Requires 40μm filtered air supply with ≤5% relative humidity.
- Automotive production line clamping fixtures
- Steel mill roller positioning systems
- Injection molding machine ejectors
- Paper processing equipment actuators
- Warehouse automated stacking mechanisms
Installation protocol:
Align cylinder axis within ±0.2° of load path. For vertical mounting,
use lock nuts on piston rod threads. Allow 50mm clearance behind end
covers for cushion adjustment. Perform initial 50-100mm test strokes
before full operation.
