Kadant Johnson Introduces High-Speed Precision Unions for Through-the-Spindle Coolant Applications



THREE RIVERS, Mich., December 7, 2005 - Kadant Johnson Inc., a subsidiary of Kadant Inc., has launched its latest high-speed precision rotary union line for through-the-spindle coolant applications in the machine tool industry. The Type G precision unions can be used with coolant, air, and hydraulic oil and are used on transfer lines, gun drills, and spindle applications at speeds exceeding 50,000 RPM.

According to Rudi Leerentveld, president of Kadant Johnson, "The market's demand for a high-speed rotary union product line that incorporates the latest mechanical seal technology drove our initiative to launch the Type G line. The competitive options offered to the market were not meeting key OEM and end user expectations, and this created an opportunity for Kadant Johnson to fill the performance gap."

The Type G line includes a full range of precision unions used in engine and transmission plants, CNC machines, clutches, spindles, and other coolant applications. The heart of the rotary union is its mechanical seal, and the Type G union is the first to offer laser etching to the seal face. This advanced manufacturing process makes distinctive laser-etched patterns on the seal face, resulting in reduced seal friction and the ability to increase rotational speed without sacrificing seal life.

Kadant Johnson's full line of Type G rotary unions is available worldwide and marketed in the Americas through Kadant Johnson's operations in the US, Canada, and Brazil. In Europe and Asia, the Type G rotary unions are marketed by Johnson-Fluiten, a joint venture of Kadant Johnson.
