Hello.

Answer me please. What is the difference in the design of 1PH8165 motors between "SANDART" and "STANDART WITH LOCATION BEARING" bearing version (14 Position of the Article No. "B" and "G")?

Please refer the attached sheet.

Block 14 number is to specify bearing. A = standard bearing & P = Advanced Lifetime.

I'm not finding a G option in my catalogs, CAD Creator or SIZER.

But, as said above, position 14 specifies various bearing options for lower vibration or longer life.

Update:

Standard bearings would be 2 ball bearings.  This is used for low axial force applications (fixed coupling, pulley).

Standard (locating bearing) fixes one of the two bearings to increase tolerance for axial forces (helical gear).  This requires a flex coupling.
