Barco E-1 Rotary Unions旋转接头
The BARCO E-1 rotary union is a dependable, economical, connection for many air, coolant, and hydraulic applications where speeds do not exceed 3500 RPM. It will handle hydraulic pressures up to 100 psi (10.3 BAR) in pneumatic use. Typical applications for the E-1 are clutches, index tables and machine tools.
Special Design Features
>Felt oil wick for seal face lubrication on pneumatic application.
>Annodized aluminum casing for corrosion resistance.
>Carbon graphite to hardened steel mechanical seals.
>Available in US and metric thread specifications.
>Low torque, for smooth running operation at high speeds.
>Oversized, widely spaced ball bearing are lubricated for life.
