5-124X G5-124X UJ335 Universal Joint 59×168 mm | 1800 Series
Description
5-124X universal joint is a heavy-duty, greaseable cross bearing for dimension-matched 1800 Series propeller shafts. Its catalogue dimensions are approximately 58.9 mm across the bearing-cup diameter and 167.5 mm across the opposite cup ends, commonly marketed as 59×168 mm. Check both measurements before selecting the part.
The photographed 5-124X universal joint kit contains one assembled cross, four installed needle-bearing cups, four black retaining rings and one separate grease fitting. The rings shown are round external-style snap rings. Final packaging details should still be confirmed on the quotation or purchase order, especially for customized or bulk orders.

Dimensions and Cross References
The 5-124X universal joint is also searched as G5-124X, UJ335, 335, HS324, 1804, U-107, CP124XE and 6228AGF.

Cross-reference numbers are useful for sourcing, but they do not replace physical measurement and retention checks.

Applications and Fitment
The 5-124X universal joint is intended for heavy-duty driveline applications that use the stated dimensions and compatible yoke arrangement. Catalogue and aftermarket listings may associate the family with selected American heavy-truck or industrial shafts, but vehicle make alone is not a reliable fitment method. Shaft revisions, replacement yokes and regional configurations can change the required joint.
Do not identify a 5-124X universal joint only by appearance or by the first two digits of a measurement. Similar large joints may use different cup diameters, overall spans, plate retainers, snap-ring locations or grease-fitting positions. A dimensionally close part can still bind, create excessive end play or fail to seat correctly.
How to Verify Before Ordering
Before ordering a 5-124X universal joint, measure an undamaged bearing cup with a caliper and confirm approximately 58.9 mm. Then measure the complete span across the opposite installed cup ends and confirm approximately 167.5 mm. Compare the snap-ring type, ring-groove location, seal profile, cup shoulder and grease-fitting clearance with the removed joint.
When installing the 5-124X universal joint, clean and inspect the yoke bores, press the cups evenly and keep every needle roller upright. Seat all four rings completely, check that the cross articulates smoothly without binding, and confirm there is no abnormal axial movement. Lubricate according to the shaft maker’s service specification.
Ordering Information
For a 5-124X universal joint quotation, send the quantity, shaft or vehicle reference, cup diameter, overall span and clear photos of the old cross and yoke retention. MR Driveline can compare samples or drawings, review cross references and discuss packing, production and export delivery requirements before order confirmation.
Frequently Asked Questions
Are 59×168 mm and 58.9×167.5 mm the same listing size?
They normally describe the same rounded dimensional family, but always compare the actual sample and tolerance requirements.
Can a cross-reference number guarantee fitment?
No. A 5-124X universal joint must still match the measured cups, total span, yoke retention and installation clearance.
