Cogged Timing Belt 8"
All Ultrafeed® Sewing Machines use two cogged belts — one for the jack drive and the other for the balance wheel. These belts do not stretch or slip.
This 8" black belt is for the jack drive's connection to the motor pulley.
Some belts have a number on the outside such as 1934 which means it is a 19-3/4" belt.
