Bernina Drive Belts / Bernina Motor V Belt / Bernina Belts Sizes Types

See the dimensions and sizes of the Bernina vintage belts in the attached tables. Of course I could not describe all the models, if you have a suggestion feel free to write a comment, there is a possibility and error in the dimensions, I write all this based on my own experience, notes and data that I found in the service instructions.
Dimensions are written in millimeters, example 5x441, where 5 is the width V of the belt and 441 is the total outer length of the belt.
Vintage Bernina mainly use V belts, Bernina 930 record use teeth belts, and older models of Bernina 125  used rubber round belt. The rubber round belt is not recommended due to stretching and oscillations during sewing on the machine, the susceptibility to stretching interferes with the proper operation of the sewing machine...etc
