  • How to measure and specify v-belts « Mind of MattJuii

    2011-12-1 · One belt had the classic profile so the signing of "20 x 3550" was to be interpreted as Li = 3550 mm. However all measurements turned out with Lw = 3522 mm so an even larger measure of 3550 mm can only be La not Li. The formula produces a result coherent with this La = Lw 31 mm = 3522 mm 31 mm = 3553 mm.
