Determination of belt type and belt width

Example for the coarse design:

Mass of linear slide ... m = 50 kg
max. acceleration (w/o delay) ... a = 20 m/s2

In the graph intersection point can be read:
BRECO® polyurethane timing belts: AT 10/ ATL 10 ... 50 mm wide
alternatively: AT 20/ ATL 20 ... 32 mm wide


The corresponding pulley of the drive pulley assemblyshould have 20 teeth (ATL = 25) or more. With a pulley with less than 20 teeth (AT), select the next larger belt width. Dimensioning see Calculation section in chapter Linear technology.
