G ROTARY UNIONS The G rotary union is a high performance, high precision rotary union for coolant, water, air, and hydraulic oil applications. The G rotary unions are generally applied to the machine tool industry for transfer lines, gun drills, spindles, drilling, milling, rotary index tables, machine tools, CNC machines, grinding machines, presses, and clutches FEATURES High precision rotary union up to 50.000 rpm and 200 bar Standard and customized rotary unions Bearingless unions available Different combination of seal materials MQL application BENEFITS Longer seal life because of laser lift technology Seals are able to handle coolant and compressed air (10 bar 15000 rpm 24 h) Mechanical seals always in contact: No leakage during commutation from coolant to dry running Low operational temperature to increase bearing life Possibility of customized tests on customers parameters
