Product description
Description of universal joint bearing:
A universal joint, or u-joint, is one of many names given to a type of gimbal-based joint design that connects two rods and allows them to bend in virtually any direction while spinning.
Other names for the design include Cardan joint, which is the common term in Europe; the now-archaic Hooke's joint; and Hardy-Spicer joint, named for a pair of inventors who developed a variant on the traditional design. A universal joint
is typically used in situations where long shafts are rotating in place and transmitting power, such as an
automobile's drivetrain.
The idea of a joint that leverages the way gimbals work has been around since the Classical eras of ancient
Greece and Rome. Its application in the transfer of motion, as it is used in modern vehicles, was not conceived
until around the middle of the 16th century by Italian scientist Gerolamo Cardano, for whom the joint is still
named in Europe. Others subsequently refined the design, and by the 19th century several variations were
patented and remain familiar in the 21st century.
A universal joint, universal coupling, U-joint, Cardan joint, Hardy-Spicer joint, or Hooke's joint is a joint orcoupling in a rigid rod that allows the rod to 'bend' in any direction, and
is commonly used in shafts that transmit.
