High-precision industrial cylinder featuring dual anti-rotation design and corrosion-resistant construction. The double-lip rod seal ensures ≤0.5mm/s leakage rate under 0.5MPa. Requires 40μm filtered lubricated air (ISO 8573-1 class 4), with recommended ISO VG32 hydraulic oil for lubrication. Features a wear-resistant guide bushing for 3,000km+ service life under normal operation.
- Automated assembly line clamping mechanisms
- Packaging machine ejector systems
- CNC machine tool fixture actuation
- Automotive welding jig positioning
- Pharmaceutical blister packaging presses
Installation protocol:
Align cylinder axis within 0.2mm angular misalignment tolerance.
For vertical mounting, install rod end downward to prevent condensate accumulation.
Lubricate every 3 months or 500km stroke distance (whichever comes first).
