NMTG Overrunning clutches are available in three basic designs.
Overrunning clutches are precision devices which lock the inner and outer races, through the wedging action of sprags/Roller to transmit torque in one direction and overrunning / freewheeling in the opposite direction. Overrunning clutch is also known as Freewheel One-Way Clutch & Holdback Devices
For more on designs/models of Overrunning clutches or for further information, refer this to know in-depth insights.
An Overrunning Clutch is a precision-engineered mechanical component designed to automatically engage and disengage torque transmission based on the rotational direction or speed of connected shafts. Also referred to as a Freewheel Clutch, One-Way Clutch, or Backstop Clutch, it allows power to be transmitted in one direction while enabling free rotation in the opposite direction. This automatic operation helps protect industrial equipment from reverse rotation, overload conditions, and unnecessary wear.
At NMTG, we manufacture high-performance Overrunning Clutches engineered for demanding industrial environments across the United States. Our clutches are designed to deliver consistent torque transmission, long service life, and dependable performance in OEM machinery as well as heavy-duty industrial systems. Every product is manufactured with precision-machined components, premium materials, and stringent quality control to ensure reliable operation under continuous-duty applications.
Whether your application requires high-speed overrunning, indexing, backstopping, or reverse rotation prevention, NMTG offers engineered solutions that meet the performance expectations of modern industrial manufacturing.
An overrunning clutch operates on a simple yet highly effective mechanical principle. When the driving shaft rotates in the designated direction, internal locking elements such as sprags, rollers, or cams engage between the inner and outer races, transmitting torque efficiently without slippage.
When the driven shaft rotates faster than the driving shaft or when rotation reverses, the locking elements automatically disengage. This creates a freewheeling condition that allows independent rotation while eliminating unnecessary friction and mechanical stress.
This automatic engagement and disengagement process makes overrunning clutches an ideal solution for applications where controlled torque transmission and reverse rotation protection are essential.
With decades of engineering expertise in industrial power transmission products, NMTG supplies reliable overrunning clutch solutions to customers worldwide. Our manufacturing capabilities, precision machining processes, and rigorous quality inspections enable us to deliver products that meet the demanding performance requirements of modern industrial applications.
Customers choose NMTG because we offer:
Selecting the appropriate overrunning clutch depends on several operating parameters, including torque capacity, shaft dimensions, operating speed, mounting arrangement, and environmental conditions. Our engineering team works closely with OEMs, industrial distributors, and end users to recommend the most suitable solution for every application.

An overrunning clutch is a mechanical power transmission device that transmits torque in one rotational direction while allowing free rotation in the opposite direction. Also known as a freewheel clutch or one-way clutch, it helps prevent reverse motion and protects industrial equipment from damage.
Overrunning clutches are widely used in industrial applications such as conveyor systems, bucket elevators, packaging machines, material handling equipment, mining machinery, cement plants, power generation systems, agricultural equipment, and automation machinery. They improve operational safety and ensure smooth, reliable torque transmission.
An overrunning clutch uses internal locking elements such as sprags, rollers, or cams that engage automatically when torque is transmitted in the driving direction. When the driven shaft rotates faster or in the opposite direction, the locking elements disengage, allowing the clutch to freewheel without transmitting torque.
There is no functional difference. Overrunning clutch, freewheel clutch, and one-way clutch are commonly used terms for the same type of mechanical device that transmits torque in one direction while permitting free rotation in the other.
Overrunning clutches are used across various industries in the USA, including mining, steel, cement, power generation, packaging, food processing, paper manufacturing, agriculture, recycling, oil & gas, construction, and industrial automation. They are also widely used by OEMs and industrial equipment manufacturers.
Selecting the right overrunning clutch depends on factors such as torque capacity, shaft size, operating speed, mounting configuration, environmental conditions, and application type. Choosing the correct model ensures reliable performance, extended service life, and efficient power transmission.
NMTG overrunning clutches are engineered for precision, durability, and consistent performance. They offer high torque capacity, low maintenance requirements, smooth engagement, long service life, and reliable operation in demanding industrial environments.
