50155 Universal Joint 50×155 mm | UJ255B 4310-2205025 for KAMAZ
Description
50155 universal joint is a heavy-duty greaseable cross-bearing kit in the nominal 50×155 mm size family. The 50 mm measurement refers to the outside diameter of each bearing cup, while 155 mm is the overall span across two opposite installed cups. This size is commonly cataloged for KAMAZ and related Russian heavy-truck propeller-shaft applications.
The photographed 50155 universal joint is supplied with one cross, four installed round bearing cups, four external circlips, one angled grease fitting and the shown protective accessory. The external circlips retain the bearing cups in the yoke. Because several 50×155 mm crosses use different cup grooves, seals or lubrication arrangements, dimensions and retention details should be compared with the removed sample before installation.
Product Features
Designed for commercial driveline repair, the 50155 universal joint combines a robust cross body with sealed needle-bearing cups and serviceable lubrication. Its outside-circlip construction makes the retaining method easy to identify during quotation and workshop inspection.
- Nominal 50 mm bearing cup diameter and 155 mm overall span.
- Four plain round bearing cups with external circlip retention.
- Greaseable design with an angled grease fitting supplied in the kit.
- Heavy-duty configuration for propeller shafts and cardan shafts.
- Neutral or customized packing available for replacement-market orders.

Cross-Reference Numbers
For sourcing and identification, the 50155 universal joint can be searched with 4310-2205025, 255B-2201025, UJ255B, 804707A1C10, 804707K8C10, 53205-2205025 and GUIS-68. These numbers are useful search references for the 50×155 mm family, but a matching number alone does not guarantee that every seal, groove and circlip position is identical.
Applications and Fitment Check
The 50155 universal joint is mainly promoted for KAMAZ heavy trucks and related Russian commercial-vehicle driveline service. Catalogs may also associate parts in this dimensional family with MAZ, KrAZ, BelAZ, agricultural machinery, graders and other equipment using compatible propeller-shaft yokes.
Before fitting a 50155 universal joint, measure the bearing cup outside diameter and the full installed span with a caliper. Check whether the yoke uses outside circlips, confirm the groove position, inspect the grease-fitting clearance and compare all four cup ends with the original component. This prevents confusion with 50×135 mm or other visually similar crosses.
