High-precision industrial cylinder featuring wear-resistant chromium coating and dual anti-rotation design. The SI63BX85's unique piston structure reduces internal leakage to <0.1 L/min @0.5MPa, with built-in magnetic slot (M9×1 connector) for position sensing compatibility. Requires 5-40μm filtered lubricated air (ISO 8573-1 class 3).
- Press machine ejection systems
- Automated palletizing arms
- Plastic injection molding clamp units
- CNC tool changers
- Conveyor gate actuators
Installation protocol:
Maintain 0.05mm/m alignment tolerance during mounting. For vertical installations exceeding 45° angle,
use external guide mechanisms. Lubricate every 5,000km travel distance using ISO VG32 hydraulic oil.
