Im still looking to find anyone knowledged in gear heads. Please reply

Please find me someone to answer this

I ordered this :

Planetary gearhead

GPX 22 HP Ø22 mm, 2-stage22 mm

16 : 1

2.4 NmCHF 157.80Details

Planetary gearhead GPX 26 LN Ø26 mm, 2-stage26 mm16 : 1

1.8 NmCHF 134.30Details

Both have the same inertia

Mass inertia1.31 gcm²

I told the sales person if there is a shaft in the middle that the lighter gear head can move the heavier gear head

He said it wont work

He said the lighter gear head will make the other gear head lighter also

It clearly says one has 15 lbs per inch and the other 21 lbs per inch

A 1 to 1 ratio gear head the increases torque is very important for many industries

Please find me someone who can help

Thank you kindly
