Air rotary union 100 series

multi-passagehydraulicpneumatic

Rotating unions allow hydraulic or air power sources to be continuously connected in rotating applications allowing the use of constant pressure hydraulic workholding on lathes, boring machines, rotary transfer tables, etc. The single circuit union is used for single-acting systems. The dual circuit version is necessary for double-acting systems or for two separate single-acting circuits. The unique design of the dual circuit union eliminates the possibility of inter-passage leakage so different fluids can be used in each circuit without danger of intermixing. For maximum seal life, combined conditions of both maximum pressure and maximum rpm should be avoided. Rotors are plated for wear and corrosion resistance. Both versions use a low torque, balanced seal design. • Single and dual circuit designs • Balanced seal design • Low torque
