Outside Snap Ring & Wing Bearing U-Joint

The u-joint series is specific to each cross measurement as described below based on the cap diameter and span over the crosses.  

Outside Snap Ring Cross

Cap Diameter:
Measure the u-joint u-joint cap diameter.  If you are measuring the end yoke, measure the width of the opening where the cap sits in the yoke.

Width: 
Measure the u-joint width by compressing the caps and measuring from outside of cap to outside of cap. When measuring an end yoke for the u-joint width measure from inside of tab to inside of tab.

Wing Bearing Cross 

Pilot Diameter: 
Pilot diameter measurement is taken over the outside of the wing bearing caps. Prior to taking measurements fully compress the bearing caps. 

Between Bolts:
Centerline of bolt hole to centerline of bolt hole on each bearing.

Cap Type:
The medium and heavy duty U-joints come in five different styles: Low Wing Threaded (LWT), Low Wing Drilled (LWD), High Wing Threaded (HWT), High Wing Drilled (HWD),  Delta Wing Threaded (TBC/DWT)

Outside Snap Ring & Wing Bearing U-Joint Sizes and Series

We recommend using a caliper or micrometer to most accurately measure u-joints. U-joint caps must be compressed when measuring dimension over the caps. Once you have recorded your measurements, refer to the dimensional charts by u-joint type.
