DC2222G Sprag Clutch for Industrial & Automotive One Way Transmission Applications
DC2222G Sprag Clutch | Compact DC Series One Way Freewheel Clutch for Industrial Applications
Introduction: What Is DC2222G Sprag Clutch?
The DC2222G Sprag Clutch is a compact DC series one way freewheel clutch designed for industrial machinery, automotive components and mechanical transmission systems.
Using precision sprag locking technology, DC2222G provides:
- One-direction torque transmission
- Automatic mechanical locking
- Freewheel operation
- Backstop protection
Unlike friction-based clutch systems, a sprag clutch uses wedge-shaped locking elements between the inner and outer races.
When driving torque is applied:
- The sprags lock instantly
- Torque is transferred efficiently
- Mechanical slip is minimized
When the driven side rotates faster:
- The sprags release
- Free rotation is achieved
- Reverse torque is prevented
This makes DC2222G suitable for compact transmission systems requiring high reliability and fast response.

Working Principle of DC2222G One Way Clutch
Locking Direction
When the driving shaft rotates:
- Inner race starts rotating.
- Sprag elements move into locking position.
- Inner and outer races engage.
- Torque is transmitted.
Benefits:
- Fast engagement
- High mechanical efficiency
- Reliable power transfer
Freewheel Direction
When the driven side rotates faster:
- Sprags release automatically.
- Relative rotation is allowed.
- Reverse torque is avoided.
The automatic switching function makes DC2222G ideal for continuous overrunning applications.
