AME Announces New and Improved Rotary Unions

Advanced Machine & Engineering Co., (AME) Rockford, IL announces new and improved OTT-Jakob GD single-passage rotary unions (1K GD).

Advanced Machine & Engineering Co., (AME)OTT-Jakob manufactures special rotary unions for a variety of operations and offers three standard types: GDR-LC, GDR and GD. The rotary unions fit into OTT-Jakob unclamp units. The unions are designed for OTT-Jakob’s power drawbars found in machine tools with a high-speed spindle and in which the machine tool feeds coolant through a single passage to the tool. The unions can also provide air blasts between tool changes. 

The parameters of the type GDR union have been improved. The maximum spindle speed now is 24,000 RPM (formerly 16,000 RPM), and the maximum coolant pressure is 80 bar instead of 50 bar. As with the type GDR-LC (16,000 RPM/maximum coolant pressure of 50 bar) and type GD (36,000 RPM/maximum coolant pressure of 80 bar), the minimum volume lubrication (externally mixed) pmax is 5 bar, the cleaning air maximum (n = 0 min-1) is 10 bar, and the pressure air maximum (n< 10,000 min-1) is 5 bar. 

The new GDP, a small rotary union designed to fit small unclamp units, has a maximum spindle speed of 75,000 RPM and a coolant pressure of 80 bar. It features a hybrid bearing, balanced design for high-speed rotation and a closed sealing surface. The minimum volume lubrication (externally mixed) pmax is 5 bar.
