WX/WXD Small Cross Universal Joint Coupling

Product Overview

The WX/WXD small universal joint coupling is designed for mechanical power transmission between two shafts operating at an angle. Featuring a compact cross-axis structure, this precision universal joint coupling is suitable for machinery that requires reliable torque transmission, flexible shaft positioning and customized bore configurations.

Available in WX single-cross and WXD double-cross configurations, the series supports different shaft connection requirements. Finished bores can be manufactured to H7 tolerance, with keyway, hexagonal or square-hole options available according to the selected design.

Apex Coupling supplies standard and customized universal joint couplings for industrial equipment manufacturers, distributors and OEM customers.

• Multiple shaft connections: Keyway, hexagonal-hole and square-hole configurations can be specified.

• Custom dimensions: Bore sizes and connection details can be reviewed according to technical drawings.

• Steel construction: Steel components provide strength for compatible industrial transmission applications.

• OEM support: Customized product requirements can be discussed with the manufacturer.

Technical Specifications

The torque range and dimensional limits apply to the series information provided and should not be interpreted as the rating of every model. Allowable torque, speed, bore dimensions and operating angle must be confirmed for the selected configuration.

WX Single-Cross and WXD Double-Cross Types

The WX type uses a single cross-joint structure. It can be considered for applications where one universal joint section is suitable for the required shaft angle and installation arrangement.

The WXD type uses a double-cross configuration. A double universal joint arrangement can help maintain more uniform angular velocity when correctly designed and installed, subject to the shaft geometry and phasing requirements.

The appropriate configuration depends on the required shaft angle, distance between shafts, operating speed and synchronization requirements.

Shaft Angle and Installation Considerations

The WX/WXD series is intended for angled shaft transmission, with a maximum angle of 45° per joint section according to the supplied product information.

The maximum permitted angle should not automatically be treated as the recommended continuous operating angle for every model. Actual performance depends on torque, rotational speed, lubrication, bearing design and duty cycle.

For a double-cross universal joint arrangement, correct installation is particularly important. To achieve uniform angular velocity, the joint angles and yoke phasing must satisfy the design requirements. Incorrect installation can lead to speed fluctuation, vibration and additional loads.

Confirm the installation arrangement with the manufacturer’s drawing before operation.

Customized Bore and Connection Options

Different machines require different shaft interfaces. The WX/WXD small universal joint coupling can be specified with suitable bore and connection options according to the selected model.

Available configurations may include:

• H7 finished bore

• Keyway

• Hexagonal bore

• Square bore

• Customized bore dimensions

• Other connection requirements subject to engineering review

When requesting a customized coupling, provide both shaft diameters, connection details and the available installation space. A technical drawing helps reduce selection errors.

Material and Manufacturing

The product series is listed as a steel universal joint coupling. The exact steel grade and heat-treatment requirements should be confirmed for the selected model.

For demanding applications, selection should account for transmitted torque, shock loading, operating speed, shaft angle and expected service life. Material and manufacturing requirements can be reviewed according to the application and customer specifications.

Typical Applications

Depending on the selected configuration, WX/WXD small universal joint couplings may be used in:

• Industrial machinery

• Automation equipment

• Packaging machinery

• Machine tools

• Mechanical transmission systems

• Equipment requiring angled shaft connections

• OEM machinery with customized shaft interfaces

The final coupling should be selected according to the equipment’s torque, speed, alignment and operating requirements.

How to Select the Right WX/WXD Universal Joint Coupling

Before ordering, confirm the following information:

1. Coupling type: WX single-cross or WXD double-cross.

2. Required torque: Include normal operating loads and starting or shock loads.

3. Operating speed: Confirm the model-specific speed limit.

4. Shaft angle: Specify the working angle for each joint section.

5. Bore dimensions: Provide the driving-side and driven-side bore sizes.

6. Connection type: Select a keyway, hexagonal bore, square bore or other approved configuration.

7. Installation dimensions: Confirm the required length, outside diameter and available space.

8. Operating conditions: Provide information about duty cycle, lubrication and the working environment.

Providing these details allows the correct model to be evaluated more accurately.

Frequently Asked Questions

What is the difference between WX and WXD universal joint couplings?

WX refers to the single-cross type, while WXD refers to the double-cross type in the supplied series description. The correct choice depends on the shaft arrangement and required transmission characteristics.

What is the maximum working angle?

The supplied product information specifies a maximum angle of 45° per joint section. The allowable continuous operating angle should be checked for the selected model and operating conditions.

Can the bore be customized?

Yes. Bore and connection options can be reviewed, including H7 finished bores, keyways, hexagonal holes and square holes, depending on the model.

What is the torque range?

The supplied series information lists nominal torque from 11.2 to 1120 N·m. The allowable torque for a specific coupling depends on its size and configuration and must be confirmed before ordering.

How do I request a quotation?

Provide the required WX or WXD type, bore dimensions, shaft angle, operating speed, torque and installation dimensions. A technical drawing is helpful for customized orders.
