Machining Options For Universal Joints

U Joint Hub Configurations

There are many ways in which input and output shafts can be connected to universal joints. The simplest way is a bore in the joint hub, into which the shaft is inserted and secured with a spring pin (or rolling pin). Alternatively, a keyway can be used to secure the shaft. A firm seat can also be achieved with square, hexagonal, splined, or threaded shaft ends. The choice of connection type depends primarily on the application and the production capabilities. In some cases, the joints are permanently welded onto the shaft.

The standard bore configurations are solid hubs, round bore or bore + keyway.

Pin bores, hex and square bores and setscrew threads also available upon request.   * Please consult Belden with full spline specifications.
