Slewing Drive Planetary Gearbox


Slewing drives are mechanical systems that rotate heavy loads in a horizontal or vertical axis. They are comprised of several components, of which the gearing material is one of the most important. In this article, we will perform a cost-benefit analysis of different gearing materials commonly used in slewing drives.

Gearing materials in slewing drives

Slewing drives can be constructed using various gearing materials, including steel, cast iron, and aluminum. Each material has its own set of advantages and disadvantages.


Steel is a popular gearing material for slewing drives due to its high strength and durability. However, it can be expensive and heavy, making it unsuitable for certain applications.

Cast iron

Cast iron is another common gearing material in slewing drives. It is less expensive than steel and is ideal for applications that require high torque and low speed. However, it is not as durable as steel and is prone to cracking.


Aluminum is a lightweight and cost-effective gearing material for slewing drives. It is ideal for applications that require high-speed rotation and low torque. However, it is not as strong as steel or cast iron and is not suitable for heavy loads.

Which gearing material should you choose?

When deciding which gearing material to use in your slewing drive, you must consider several factors, including the load capacity, speed requirements, and environmental conditions. For heavy-duty applications that require high torque and durability, steel or cast iron is the best choice. For high-speed applications that require lightweight components, aluminum is the optimal choice.


In summary, the gearing material you choose for your slewing drive will depend on your specific application requirements. By performing a cost-benefit analysis of the different materials available, you can select the most suitable option for your project.

Planetary Gearbox/Reducer Purchasing Guide

When purchasing a planetary gearbox/reducer, there are several factors that you should consider to determine which parameters are important. These factors are listed in the table below:

Parameter Description
Speed ratio The ratio of input speed to output speed
Backlash The amount of play between the gears
Efficiency The ratio of output power to input power
Torque capacity The maximum amount of torque that the gearbox can handle
Shaft orientation The orientation of the input and output shafts
Environmental conditions The operating temperature, moisture, and other environmental factors that may affect the gearbox
