Description
5-281X Universal Joint – 1810 Series Bearing Plate
The 5-281X universal joint is a heavy-duty 1810 Series cross-bearing assembly for commercial driveline repair. It uses a full-round bearing-plate retention design and is greaseable for routine service. The key measurements are a 49.225 mm (1.938 in) bearing cap diameter and a 191.694 mm (7.547 in) bearing-plate dimension.
This listing is for the bearing-plate/full-round configuration. It should not be selected from dimensions alone as a substitute for an outside-snap-ring or half-round universal joint. Compare the original part number, both measurements, yoke design, plate geometry and bolt pattern before ordering.

Cross Reference Numbers
Verified catalogue and market comparison references for the 5-281X universal joint include Dana Spicer 5-281X, Neapco 6-0281, Meritor CP18N, Rockwell/Meritor R-281X and Precision 381. Buyers may also search the no-hyphen form 5281X.
Cross-reference numbers are provided for identification and quotation support. Brand specifications, seals, grease fittings, hardware and manufacturing revisions can differ, so physical dimensions and bearing-plate geometry must be checked before interchange is approved.
Typical Applications
The 1810 Series bearing-plate joint is used in heavy-duty truck and commercial driveline service where a large full-round cross and bolt-on plates are required. It is suitable for replacement enquiries from driveline workshops, fleet-maintenance operations, truck-parts distributors and rebuilders.
Vehicle model alone is not enough to confirm fitment. Propeller-shaft, axle, yoke and production variations can change the required universal joint even within the same vehicle family.
Installation and Verification
Before 5-281X universal joint installation, clean and inspect the yoke faces, plate seats and bolt threads. Keep the needle rollers correctly positioned while fitting the bearing cups, install the matching plates and hardware, and tighten all fasteners to the vehicle or driveline manufacturer’s specification. After assembly, confirm smooth articulation, correct shaft phasing, lubrication and driveline balance.
For compatibility checking, send MR Driveline the original part number, bearing cap diameter, plate-to-plate dimension, bolt pattern, yoke photographs and required quantity. A sample or dimensional drawing is recommended when the original number is unavailable.
