Shaft Mounted Speed Reducer Manufacturer
Jaycon Gear is a well-known manufacturer of Shaft Mounted Speed Reducer (SMSR) Gearboxes, committed to improving the performance, efficiency, and durability of power transmission systems.
What is a Shaft Mounted Speed Reducer?
A shaft mounted speed reducer is a gearbox that is installed directly onto the shaft of the machine it drives. It helps to reduce the speed of the motor while increasing the torque, making the machine capable of working at the required speed and power.
This type of speed reducer is primarily used in conveyors, material handling equipment, mixing devices, and industrial machinery where compactness and high reliability of the power transmission system are necessary. It is assembled directly on the shaft, which enables saving the installation space.



Key Features
- Direct Shaft Mounting – Fits directly onto the machine shaft, reducing the need for extra mounting arrangements.
- Compact Construction – It occupies less installation area than traditional gearboxes.
- High Torque Output – Produces the torque necessary to run heavy machinery.
- Dependable Power Transmission – Transfers motion effectively from the motor to the driven machine.
- Easy Installation – Simple mounting and alignment make installation more convenient.
- Low Maintenance – Designed for dependable operation with minimal maintenance requirements.
- Strong Construction – Built to withstand continuous industrial working conditions.

How Does a Shaft Mounted Speed Reducer Work?
Mechanical Power Input
The motor supplies mechanical power to the gearbox to drive the connected machinery.
Speed Reduction
The internal gears reduce the input speed according to the required gear ratio.
Increased Output Torque
The gearbox increases output torque, enabling the machine to perform its intended work.
Compact Power Transmission
Direct mounting on the driving shaft simplifies installation and saves space compared with conventional gearbox arrangements.
FAQ's
The Shaft Mounted Speed Reducer is fixed directly onto the driven shaft of the equipment, thus saving on base, coupling, and belt drive arrangement. A normal gearbox is normally installed separately and coupled either through belt or coupling arrangement.
Gear ratio available in our SMSR gearboxes ranges between 5:1 to 25:1 according to applications and torque requirement. Ratio higher than 25:1 can be made available upon request.
