1.2.3.2.1.2 Mounting a hollow-shaft secondary bearing
When the hollow shaft is connected to the actuator output shaft it is normally quite long and only supported
by a bearing on the side of the gear system. Therefore, it is important to support the shaft on the opposite
side of the actuator to prevent the shaft from an eccentric motion. If it is not supported properly this might
result in poor performance or even failure of the corresponding position encoder.
Note
The bearing adapter must be designed individually according to each application.
The top side of Circulo provides multiple threaded M2 holes and two holes for 3 mm dowel pins. In this
application example a ball bearing (61803) is fitted to this interface to align the output shaft.
