Errors in rotation
Transmission Error is the error introduced into a system by an inconsistent transfer of motion from one side to the other.
As a system component the Reli-a-Flex® coupling will only introduce very small velocity and hence position fluctuations.
This coupled with a stiffness greater than 10 times single spiral couplings means that in bi-directional movement applications (as shown on the graph) Reli-a-Flex® is the only choice.
