Parallel elastic coupling is the elastic coupling that takes into
account the fact that the cutting groove is shorter without
weakening the ability to withstand the correction deviation. The
material is aluminum alloy or stainless steel.
This performance makes it suitable for light load applications. For
example, the connection between the servo motor and the ball screw.
However, this performance with the increase of groove size, the
bearing load will increase, but in most cases, can be effective
enough to protect the bearing. Increasing size means increasing the
ability to withstand eccentricity.
