U-Joints have no backlash and no moving parts.
Press Release Summary:
One piece universal joints can accommodate angular misalignments up to 90 deg. They also compensate for axial and parallel misalignment, while keeping velocity constant. Because of 1-piece, flexure construction, U-joints are able to maintain constant radial load at all points of rotation. They do not require lubrication.

One Piece U-Joints Feature Zero Backlash, No Moving Parts
SANTA MARIA, CA., February 20, 2002 - One piece universal joints from Helical feature zero backlash and can accommodate angular misalignments up to 90 deg. Using the HELI-CAL(R) Flexure concept, the u-joint also compensates for axial and parallel misalignment, while keeping velocity constant. Because of their one piece, flexure construction, Helical's u-joints are able to maintain a constant radial load at all points of rotation. The product does not require lubrication. FACTS ABOUT: Helical Products Company, Inc. is a U.S. company that designs and manufactures couplings, U-joints, machined springs, and power transmission couplings for both domestic and international markets. Its products are sold through manufacturer's agents and distributors. The firm has been in business 40 years, and is known world wide for its quality product and excellent service. The HELI-CAL Flexure, is a continuous flexible beam that gives special flexing qualities to the three primary Helical products. The flexure can take on many characteristics, depending on the particular coil and material utilized. The unique HELI-CAL Flexure can be applied to the use of magnetic or non-magnetic corrosion resistant stainless steels, as well as aluminum alloys, Delrin and titanium. Because of the way Helical has organized and automated its proprietary production processes, customers can initiate the manufacture of a specified part today and be assured of an exact replacement of the original for years to come. Thousands of HELI-CAL Flexures can be found in applications ranging from satellite instruments and scientific apparatus to conveyors and oil field equipment. Helical's engineers enjoy an impressive track record of precisely matching the dimensional and operational characteristics of a broad array of applications. Helical has the unique ability to take a piece of bar stock and make it flexible, utilizing the HELI-CAL Flexure. Since its beginning, the HELI-CAL Flexure has been refined and developed to accommodate a wide range of applications. Our ability, combined with our expertise and quality workmanship, will continue to be the backbone of Helical's products. Our patents and manufacturing processes have enabled us to progress and become recognized as a distinct organization which supplies what is now known as the Helical coupling. We are different because every HELI-CAL Flexure performs multiple functions without separate parts or the associated backlash usually associated with multi-piece flexible couplings. Helical's reputation has been established by giving excellent service working directly with the customer engineers, on time delivery, and last but not least, the production of quality products. In essence, WHAT WE SAY, WE DO.
