up to 30°for single type, up to 60° for dual type、up to 15°for KF, up to 30° for KL and KFD

The larger the joint angle becomes, the more the speed fluctuation of the output shaft is amplified periodically in accelerated and decelerated operation.

For this reason, the twisted effect on a shaft and a joint is increased resulting in the decreased efficiency in power transmission. Therefore keep the joint angle as small as possible.
