High-precision industrial cylinder featuring wear-resistant piston guides and dual-layer sealing system. The extended 820mm stroke version utilizes anti-buckling rod design with chromium-plated surface treatment (Ra≤0.4μm roughness) for smooth operation in heavy-load applications. Requires 5-40μm filtered compressed air with lubrication (ISO VG32 recommended).
- Automotive assembly line clamping mechanisms
- Sheet metal stamping press ejection systems
- Palletizing robot end-effector actuators
- Plastic injection molding machine core-pulling
- Conveyor gate control in food processing lines
Maintenance advisory:
Lubricate through air supply (oil mist type) every 3 months under normal operation.
Avoid lateral force exceeding 30N on piston rod. For vertical mounting,
use rod-end support brackets (sold separately).
