Woodward UA201109 U-Joint – .750-20 x .550 Double D
The Woodward UA201109 U-joint is a precision steering universal joint for professional motorsport and high-performance steering systems.
This configuration combines the Woodward 201 .750"-20 spline with a Woodward 109 .550" Double D, providing a direct and compact connection between steering components using these a Woodward spline and a Double D shaft profile.
Engineered for demanding steering applications, Woodward universal joints combine high strength, accurate spline engagement and minimal rotational play in a compact assembly.
Connection Specifications
| Specification | Side 1 | Side 2 |
|---|---|---|
| Woodward connection | 201 | 109 |
| Type | Splined | Double D |
| Nominal diameter | .750" | .550" |
| Spline count | 20 | Not applicable (Double D) |
| Description | .750"-20 spline | .550" Double D |
Woodward 201 – .750"-20 Spline
The Woodward 201 connection uses Woodward's .750"-20 spline profile and is used throughout the Woodward professional steering component range.
Correct spline identification is important. Nominal diameter and tooth count alone do not guarantee compatibility, as the actual spline geometry must also correspond.
A generic .750"-20 spline should therefore not automatically be assumed to fit a Woodward 201 connection.
Woodward 109 – .550" Double D Profile
The second side of the UA201109 features the Woodward 109 spline, with a nominal diameter of .550" Double D shaft profile.
This configuration allows a component using the Woodward 201 profile to be connected directly to a steering shaft or component with the corresponding 109 Double D profile, without requiring a separate profile adapter, provided both mating profiles match.
Always verify shaft diameter, Double D flat dimensions and spline profile when selecting a steering U-joint.

*Joint weight varies by configuration; shipping weight is set to 1 kg. Failure torque thresholds are not continuous working torque ratings.
Operating Angle
The Woodward UA201109 permits angular misalignment up to 32 degrees. For normal steering operation, Woodward recommends keeping the working angle below 20 degrees.
A smaller operating angle reduces angular velocity variation through the universal joint and helps maintain smooth and consistent steering response.
Where packaging requires a larger change in steering shaft direction, using two correctly phased U-joints and an intermediate shaft can provide a better solution than operating a single joint close to its maximum angle.
Professional Motorsport Steering Component
The compact design and high mechanical strength of the UA201109 make it suitable for demanding steering installations including:
- Professional motorsport
- GT and touring cars
- Prototype race cars
- Rally cars
- Track and competition cars
- Custom steering shafts
- Custom steering columns
- Purpose-built vehicles
Woodward U-joints are particularly useful in tightly packaged vehicles where the steering shaft must negotiate chassis tubes, suspension components, engine installations or other obstructions.
Hydroline supplies genuine Woodward Steering components for professional motorsport and performance applications, including universal joints, splined shafts and specialist steering components.
