WebBacklash refers to the play, or clearance, between meshing gears inside the gearhead of a motor. Torsional backlash is measured when about 2% of the load torque is applied to the gear shaft. It contains a casing, gears, shafts, and bearings. When the gears mesh together, there is actually a tiny gap between the gears.
