Torque 4 in-lbs [.45 Nm] Product Disclaimer Values listed are dependent on a combination of all application parameters. Please note operational life is dependent upon both rotational speed and duty cycle. Contact DSTI if your application requires operating close to the maximum rotational speed with a continuous duty cycle.
Applications with temperatures above 220° F (105° C) require alternative seal materials. Applications using Water with temperatures above 212° F (100° C) require alternative seal materials. Please consult with DSTI regarding your specific application requirements.
Value listed for the minimum torque required to rotate is based on zero pressure using air/gas. Required torque to rotate may be greater when using other media types. For specific torque requirements, please contact DSTI to discuss your application.
DetailsThe SPS-5910 single passage rotary unions are compact, lightweight and corrosion-resistant featuring a stainless steel shaft and hardcoat anodized aluminum housing. It comes standard with a 2" male NPT threaded shaft connection, a 2" female NPT threaded housing connection and two tapped holes on the end of housing for easy equipment integration.
The shaft and housing materials makes this a excellent, low-cost solution when transferring (under pressure or vacuum) water, coolant, hydraulic oil or air from a stationary source to a rotating component.
