DC4445T Yamaha Supercharger One Way Clutch (20 Sprag Wedges) for Marine Applications
Introduction: What Is DC4445T Yamaha Supercharger Clutch?
The DC4445T Yamaha Supercharger One Way Clutch is a precision-engineered marine sprag freewheel clutch designed specifically for Yamaha high-performance watercraft applications.
This component is installed inside the supercharger drive system, where it controls the power transmission between the engine and the supercharger assembly.
The main functions of DC4445T include:
- Efficient transmission of engine power
- One-direction torque locking
- Automatic overrunning function
- Protection of supercharger drive components
Unlike conventional bearings, a one way clutch combines rotation support with automatic mechanical locking.
When the engine drives the supercharger:
- Internal sprag elements lock
- Torque is transferred efficiently
- Supercharger operates normally
When the rotation condition changes:
- The clutch releases automatically
- Reverse impact is reduced
- Internal components are protected
The DC4445T is designed for Yamaha marine power systems requiring stable performance under high-speed and high-load operating conditions.

Working Principle of DC4445T Yamaha One Way Clutch
The DC4445T operates through precision sprag locking technology.
Drive Mode
When engine power is transmitted:
- Sprag wedges move into locking position.
- Inner and outer races engage.
- Torque drives the supercharger.
Freewheel Mode
When rotational speed changes:
- Sprag wedges release.
- Components rotate independently.
- Reverse torque impact is minimized.
This automatic operation improves supercharger system efficiency and durability.
