Belt drive motor
Belt drive motors are an economical and practical alternative to direct drive. They absorb large amounts of shock and vibration without the need for a gearbox, and can be switched between speed and torque by adjusting the size of the pulley in the belt drive system.

Belt or gear drives generally impose a greater load on motor bearings than coupling drives. Therefore, belt and gear drives most often use cylindrical roller bearings at the drive end.
Compared to direct-coupled applications, motors for belt drive applications can withstand a wide range of load bearing conditions. The bearing in the fixed position of the belt drive system is affected by the increase of the radial load of the belt itself, and the risk of misalignment increases. And, since misalignment is one of the most common causes of premature belt failure, the fixed position of a reliable belt drive system requires robust bearings.
