The planet carrier is a cage, which provides stiffness and acceleration capacity. It is monobloc with the output shaft.
High radial loads can be accepted thanks to the 2 radial ball bearings supporting the shaft.
The planetary ring is monobloc (belongs to the housing), to reinforce stiffness.
This construction improves acceleration capacity and acceptance of torque variations.
We recommend this line for applications using application factor Ka<1.45 (refer to the information section for more details about application factors).
