The bodies of air and water rotary unions are made of highly durable aluminum alloy, medium carbon steel rotors, and high-quality bearings to provide the best result.
An air or water rotary union is one-way passage. Please follow the dimensional drawing to connect the air inlet or water inlet.
Forbid to use any lubricant or cooling fluid.
The max operating pressure for air rotary union is 10kgf/cm2, and for water rotary union is 30kgf/cm2.
The suitable rotational speed is below 900min-1. The rotational speed between 1000 to 2000 min-1, is only available for air rotary unions.
