An Introduction to Hollow Shaft Gearmotors

October 10, 2017

Gear motors have continued to increase efficiency in load carrying capacities of machines in many industries. Different applications use different types of gear motors. One of the most commonly used gear systems are hollow shaft gearmotors. Their most common application is in pulley and lever systems.

A shaft is a rod that carries rotational loads. The hollow shaft has its central material removed in order to reduce the weight it adds in the process while maintaining the same torque.


The space in hollow shaft gearmotors allows for design flexibility and can be very useful in cooling the system.


The hollow space can be used for fluid motion.

These gearmotors are compact and are therefore easily applied even with limited space. Most hollow shaft gearmotors are made of stainless steel. This means that they can endure great tensile stress for long periods of time as well as resist corrosion. This durability feature saves resources that can otherwise be used for repairs and replacements.

Besides durability, hollow shaft gearboxes are recyclable and reusable in other applications. This limits the pollutants released to the environment. This also means that the pollution risks to humans and the rate of environmental degradation are reduced significantly. Hollow shafts are also very easy to clean, thus demanding little in terms of maintenance. All these features make the hollow shaft gearmotor highly cost-effective.
