50135 Universal Joint 50×135 mm | 5320-2205025 131-2205025 for KAMAZ
Description
50135 universal joint is a heavy-duty greaseable cross-bearing kit in the nominal 50×135 mm size family. The first measurement is the outside diameter of each bearing cup, and the second is the overall span across two opposite installed cups. This dimensional family is widely searched for KAMAZ and related Russian commercial-vehicle propeller shafts.
The photographed 50135 universal joint includes one cross, four installed round bearing cups, four external circlips, one angled grease fitting and the shown protective accessory. External circlips retain the bearing cups in the yoke, while the serviceable lubrication point supports scheduled maintenance. Actual packing can be confirmed with the sales order.
Product Features
Built for driveline repair and replacement supply, the 50135 universal joint combines a robust cross body with four precision-machined bearing cups. Its outside-circlip construction is easy to identify during workshop inspection, and the separate angled fitting provides access for grease after installation when the yoke has suitable clearance.
- Nominal 50 mm bearing cup diameter and 135 mm overall span.
- Four plain round bearing cups with external circlip retention.
- Greaseable design with an angled fitting supplied in the photographed kit.
- Heavy-duty configuration for propeller shafts and cardan shafts.
- Neutral packing and customized packing options for replacement-market orders.

Cross-Reference Numbers
For sourcing and identification, the 50135 universal joint may be searched with 5320-2205025, 5320-2205025-01, 131-2205025, 131-2205025-03, 53205-2201025 and 6520-2201025. These numbers are useful references for the 50×135 mm family, but a reference alone does not prove that every cup groove, seal and circlip position is identical.
Applications
The 50135 universal joint is promoted primarily for KAMAZ heavy-truck driveline service. Catalogs may also associate members of this dimensional family with ZIL, Ural, MAZ, LAZ, K-701 and other vehicles or equipment using compatible propeller-shaft yokes. Vehicle model, shaft assembly number and production year should be checked before purchase.
Fitment Check
Before installing a 50135 universal joint, measure the cup outside diameter and the full tip-to-tip span with a caliper. Confirm that the yoke uses external circlips, compare the groove positions, inspect grease-fitting clearance and check the seals against the old component. This prevents confusion with 50×155 mm and other visually similar heavy-duty crosses.
Clean the yoke bores, press each cup evenly and never apply installation force through the needle rollers. After the circlips are seated, verify that the cross articulates smoothly without binding. Follow the vehicle or shaft manufacturer’s torque and lubrication instructions.
Ordering Information
When requesting a quotation for the 50135 universal joint, send the required quantity, application, reference number and clear photos of the old joint or yoke. For mixed-model orders, list each size separately. MR Driveline can review drawings, dimensions or samples before production confirmation.
