APPLICATION EXAMPLE
Locking type B
Locking type C
GRI rigid couplings have been designed and manufactured to connect two sha
Ō
s of the same diameter but without allowing any relevant
misalignment.
The coupling is manufactured in one element for the single split version. A two piece unit is available on request allowing simple and fast
moun
Ɵ
ng and dismoun
Ɵ
ng.
The nominal torque of the coupling must be higher than the maximum torque of the motor's side, according to the generic formula on page 6.
The indicated torque values have been calculated based on a fric
