Standard Belt Thicknesses and Widths

Standard Belt Thicknesses and Widths Points : standard belt thicknesses and widths Standard flat belt thicknesses are 5, 6.5, 8, 10 and 12 mm. The prefer values of thicknesses are as follows:
i. 5 mm for nominal belt widths of 35 to 63 mm
ii. 6.5 mm for nominal belt widths of 50 to 140 mm
iii. 8 mm for nominal belt widths of 90 to 224 mm
iv.10 mm for nominal belt widths of 125 to 400 mm
v. 12 mm for nominal belt widths of 250 to 600 mm

Usual values of nominal belt widths are in R10 series, starting from 25 mm upto 63 mm and in R 20 series starting as of 71 mm up to 600 mm. Therefore, standard widths will be 25, 32, 40, 50, 63, 71, 80, 90, 100, 112, 125, 140, 160, 180, 200, 224, 250, 280, 315, 355, 400, 450, 500, 560 and 600 mm.
