CA-141 Universal Joint 39×118 mm

CA-141 universal joint is a greaseable propeller-shaft cross kit identified by the customer as CA-141 and measured in the 39×118 mm size group. In this description, 39 mm refers to the nominal outside diameter of each bearing cup and 118 mm refers to the nominal overall span measured across the opposite installed bearing cups. The photographed supply configuration contains one forged cross assembly, four installed plain round bearing cups, four separate external snap rings and one side-mounted grease fitting.

This product page keeps CA-141 as the primary model because it came with the customer’s part identification. CA141 and CA 141 are common writing variants, while EQ140 is frequently used as a related aftermarket search. Catalog data is not perfectly uniform: some catalogs publish CA141 as 39×118 mm, while another catalog distinguishes CA141 at 38×118 mm and EQ140 at 39×118 mm. That difference is important. The model name alone should not be used as the only fitment check.

Product Features

Heavy-duty forged universal-joint cross for driveline and propeller-shaft service.
Customer-specified CA-141 model in the nominal 39×118 mm dimensional group.
Four plain round bearing cups with external snap-ring retention.
Four loose circlips supplied for installation in the yoke grooves.
Serviceable lubrication design with a side grease fitting on the cross body.
EQ140 keyword coverage for buyers researching the closely associated 39×118 mm family.

Correct installation is essential to the life of a CA-141 universal joint. Clean the yoke bores, check them for distortion and press each bearing cup squarely. Do not allow a needle roller to fall under the trunnion. Seat all four snap rings completely, then confirm free articulation without tight spots. Propeller-shaft phasing, runout and balance should also be checked before the vehicle returns to service.

Model and Cross-Reference Notes

Searches for this CA-141 universal joint may also appear under CA141, 39×118 universal joint, EQ140 and supplier reference ST80004. These terms help distributors and workshops locate the dimensional family, but they do not prove automatic interchange. EQ140 is especially useful for search visibility because many aftermarket suppliers group CA141 and EQ140 together. However, catalog differences around the nominal 38 mm or 39 mm cup diameter mean that the physical sample remains the deciding reference.

Before ordering, measure one clean bearing cup with a caliper, then measure across two opposite installed cups. Also compare the outside snap-ring grooves, circlip thickness, seal position and grease-fitting clearance. If the removed joint measures closer to 38 mm than 39 mm, send the exact reading and photographs so MR Driveline can check the correct variant rather than assuming it is the pictured part.

Typical Applications

The CA-141 universal joint is commonly marketed for selected Chinese truck, commercial-vehicle, agricultural and industrial propeller-shaft applications using an external-circlip cross. Actual fitment can change with vehicle year, axle, gearbox, propeller-shaft manufacturer or a previously replaced shaft. For this reason, this page does not claim one universal vehicle list from the model code alone.

For a fast quotation on this CA-141 universal joint, provide the CA-141 marking, required quantity, 39 mm cup measurement, 118 mm overall measurement and a clear image of the old joint and yoke. If available, include the truck model, shaft number or packaging label. These details allow the sales team to compare both CA141 and EQ140 catalog lines while avoiding a size mismatch.

Why Choose MR Driveline

This approach makes the CA-141 universal joint easier to search while keeping the important compatibility limits visible. We support distributors, workshops and fleet buyers with measurement checking, samples, packaging options and repeat supply.

FAQ

Are CA-141 and CA141 the same model?

Yes. CA141 and CA 141 are common spacing variations of CA-141. They belong on the same product page rather than separate duplicate pages.

Is CA-141 always exactly 39×118 mm?

No catalog-wide guarantee should be made. Several supplier catalogs use 39×118 mm, while at least one established catalog lists CA141 as 38×118 mm. Confirm the bearing cup with a caliper before purchase.

Can EQ140 replace CA-141?

EQ140 is a strong cross-search reference for the 39×118 mm family, but interchange must be confirmed from the cup diameter, total span, external snap-ring grooves and installation clearance.

What is included in the photographed kit?

The photographed CA-141 universal joint kit includes one cross with four installed bearing cups, four external snap rings and one grease fitting.

What information should I send for confirmation?

Send the model marking, exact cup diameter, exact overall span, circlip arrangement, quantity and clear photos of the removed joint. A physical sample or drawing is best when measurements are close.
