s.s. white technologies flexible shaft specializing in rotary motion solutions for the aircraft, medical, automotive, and industrial markets. more than half the cars produced in the us today carry one or more of s.s. white's flexible shafts. every aircraft produced in the world, whether helicopter, military jet, jumbo airliner (except the russian jets), or prop plane has at least one s.s. white flexible shaft on board. we are considered the world leader in the design and manufacture of flexible shafts and related assemblies. flexible shafts are often the preferred choice for rotary motion transmission over gear boxes, universal joints, and belts-and-pulleys in industrial and medical fields as well as in consumer items. further, universal joints can be off-set only up to 15-20 degrees after which the change in angular velocity becomes objectionable. flexible shafts go up to 90 degrees without any discernible change in performance.
