Speed Reducers
Speed reducers, commonly known as gear reducers, are the unsung heroes of heavy industry. These mechanical devices are designed to take the high speed and low torque from a motor and convert it into controlled, high-torque power suitable for demanding machinery. Whether you’re in mining, manufacturing, or material handling, a speed reducer ensures your equipment operates at the precise speed required, protecting components and maximizing efficiency.
At Nhanhiso Masodzi Group (Pty) Ltd (NMG) , your trusted partner in Rustenburg for MRO and Trackless Mining Machine Components, we provide expert solutions to keep your operations running smoothly.
SPEED REDUCERS BY CATEGORY
Parallel Shaft Speed Reducers
Ideal for heavy-duty applications, parallel shaft speed reducers feature gears mounted on parallel shafts. They are the go-to choice for significantly decreasing rotational speed while dramatically increasing torque. Their robust design ensures efficient and reliable power transmission for large conveyors and industrial drives.
Right Angle Speed Reducers
When space is at a premium, a right angle speed reducer is the perfect solution. By positioning the output shaft at a 90-degree angle to the input, these compact units efficiently transmit power around corners, providing precise torque output in tight machine configurations.
Reducer Parts and Accessories
Maintaining your speed reducers is critical for uptime. NMG stocks a comprehensive range of genuine components and supplementary items, from torque arms and shaft kits to backstops. We have the parts to enhance functionality and simplify maintenance.
Inline/Concentric Speed Reducers
Designed for applications requiring perfect alignment, inline or concentric speed reducers maintain a coaxial input and output shaft configuration. They provide a straight-line power transfer, making them essential for precise, space-efficient drive systems where alignment is non-negotiable.

ABOUT SPEED REDUCERS: THE NMG PERSPECTIVE
In the world of heavy industry, speed reducers are the key to maintaining smooth, controlled, and efficient operations. They take the frantic energy of a high-speed motor and translate it into the steady, powerful force needed to move mountains—or just move material across a mine site. By ensuring the correct speed and torque, they provide the precision required for critical tasks and significantly extend equipment lifespan by reducing mechanical strain and wear.
Speed reducers are available in three primary configurations, each suited to different operational needs:
1. Right Angle Speed Reducers
A right-angle speed reducer alters a motor’s output speed and torque, but with a unique spatial benefit. It uses a set of gears (often worm or bevel) arranged so the output shaft sits at a 90-degree angle to the input. When the motor spins the input shaft, the interlocking gears transfer that motion to the output shaft, efficiently turning the corner. This configuration is a lifesaver in compact machinery where a straight-line drive simply won’t fit, allowing for more efficient machine designs in cramped spaces.
2. Inline/Concentric Speed Reducers
An inline or concentric speed reducer operates on the classic principle of gear reduction using multiple gears within a sealed housing. The high-speed input shaft spins a small gear, which meshes with a larger gear on the output shaft. This simple, effective interaction creates the necessary reduction. The beauty of this setup is the straight-line power transfer, which makes these reducers ideal for applications where perfect alignment between the motor and the driven component is crucial for smooth operation.
3. Parallel Shaft Speed Reducers
Parallel shaft speed reducers feature gears (typically helical) arranged on parallel shafts. They are workhorses that efficiently convert high-speed, low-torque input into low-speed, high-torque output. Known for their high efficiency and compact footprint, they are specifically designed to handle the high radial and axial loads common in heavy industrial applications like large conveyors, crushers, and mixers.
