A 2Nm motor M is used to drive the system through a gear drive and a chain drive. the overall reduction ratio is to be between 16:1 and 18:1, and at an output speed of 6rpm.

$\begingroup$ i would like to design a gear and chain drives of this system and select the suitable ball bearings for the shaft $\endgroup$– dumisani mthethwaNov 12, 2019 at 10:05

As Yaniv Ben David states this post needs some clarification. Add a sketch and some more information.
Assuming "shaft axis" is the output shaft and the transmission goes from fast at motor shaft to slow at output shaft the maximum torque is:
$ T_{out,max} = i \cdot T_{mot,max} = 32 Nm \dots 36 Nm $ for 'typical' electric motors at low speed.
Considering a rough estimate 10% losses in the drive train, this means you get approx. 29 Nm of torque on the output shaft.
