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

I would like to buy Drive belts for Bernina 810 - Dimensions are 5X229 and 6X422 - Do you sell them . or could tell me where to buy them please - with thanks
ReplyDeleteNo, I'm not selling, the original belts don't exist, you have to find a replacement
DeleteFor the Bernina 807, with a 5x229mm belt. The aftermarket belts are 6 mm. Do you think the 6 mm belt will still be ok? Because the belts are sometimes undersized, I've going to try a 240 mm, and am hoping for the best.
ReplyDeleteYour Benina had a 5 mm wide belt and you bought a slightly longer 6 mm wide one.? The only thing I can say is that you call back and let us all know if your version worked.
DeleteIt is certain that the 6 mm belt will not have a good fit on the pulley and this can lead to slipping.
