Mechanical Speed Variator

The BEIER VARIATORÒ in an adjustable speed traction drive through an ingenious frictional transmission mechanism using multiple metal discs. The adjustable speed traction drive was invented by Dr. Joseph Beier
After studying the development of BEIER VARIATOR for many years, Sumitomo entered into a tie-up with HIVAG Corporation in Liecthenstein, to which Dr. Beier belonged, and began production in Japan in 1952. Production outpaced the high economic growth rate enjoyed throughout Japan during this time. By 1990 total production of BEIER VARIATOR had over 500,000.
Since Sumitomo first started producing BEIER VARIATOR, the company has designed a variety of complementary products and control devices to meet a wide diversity of customer needs. BEIER VARIATOR is currently the most advanced adjustable speed traction drive produced, and serve hundreds of industries throughout the world.
