3 Overview The Type G rotary union is a high performance, high precision union for coolant, air, and hydraulic oil applications. Type G unions are generally applied to the machine tool industry for: u Transfer lines u Gun drills u Spindles u rilling u Milling u Machine tools u N machines u Grinding machines u Presses u lutches u Rotary index tables ased on more than 4 years of mechanical seal design and application expertise, the Type G rotary union line is built to perform under the most demanding conditions. thorough understanding of seal load optimisation, seal wear characteristics, and application knowledge means the Type G union can provide years of reliable service for coolant, air, and hydraulic oil applications. Precision rotary unions designed for smooth running, high speed coolant, air, and hydraulic oil applications. Measuring and controlling seal design ensures leak-free operation. Rotor concentricity is measured to allow vibration-free operation. Laser etched hydrodynamic grooves provide improved seal performance. 3

19 Recommendations Installation and operation recommendations Type G rotary unions are high-precision components that provide smooth running operation at high speeds. ue to the precise manufacturing tolerances, these unions require care during installation and maintenance. Installation instructions are available online at or from your local adant Johnson sales office. lexible hose To ensure free movement of the union and elimination of side loading, the proper installation, type, and length of flexible hose should be used. adant Johnson recommends S 1R1 Type T single-braid hose. The minimum length of hose is 3 mm for a one-piece installation. Hose should be a minimum of 3 mm long. Yes No No Yes Lubrication The seal faces in all Type G rotary unions are lubricated by the media (coolant, hydraulic oil, etc.) passing through the union. The uto-off seal device found in the GX, GZ, and G55 unions permits dry running. ll ball bearings are lubricated for life and require no additional lubrication. iltration It is important to follow the filtration requirements recommended by the machinery OM. Type G unions do not require additional filtration other than what is recommended for the coolant pumping system. Guarantee Type G unions are tested prior to shipment and are warranted against manufacturing defects for 12 months. adant Johnson s global sales and service network stands behind its products and provides support to more than 15 countries worldwide. 19
