G5-6128X 5-6128X 1S9670 Wing Bearing Universal Joint 42.8×140.4 mm | 4HWD
Description
G5-6128X universal joint is a greaseable four-wing heavy-duty cross bearing for construction machinery and other high-load propeller-shaft applications. Its key catalogue dimensions are a 42.8 mm bearing-cap diameter and approximately 140.4 mm overall span. The wing-bearing layout must be checked together with these measurements before selection.
The photographed G5-6128X universal joint is supplied as an assembled four-wing cross with mounting bolts, split spring washers and a service grease fitting. Each wing cap has two mounting holes, allowing the joint to be secured to a matching driveshaft yoke. Kit contents should be confirmed on the quotation for production or customized orders.
Product Features
MR Driveline prepares the G5-6128X universal joint for professional driveshaft rebuilding where conventional round bearing cups and external circlips are not suitable. The machined wing caps, forged cross body and serviceable lubrication point support heavy-equipment driveline maintenance.
- 42.8 mm nominal bearing-cap diameter.
- 140.4 mm nominal overall span.
- Four heavy-duty wing bearing caps with two mounting holes per wing.
- Greaseable construction for scheduled lubrication.
- Mounting bolts and split spring washers shown with the kit.
Technical Identification
The G5-6128X universal joint is commonly cross-referenced as 5-6128X, 1S9670 and 145-14-00190. Additional aftermarket references include CP62N-HWD, 114-6285 and 3-66059. Some catalogues classify the configuration as 4HWD, meaning four heavy-duty wing-style bearing caps. Cross references assist sourcing, but the sample and yoke dimensions remain the final fitment authority.

Applications and Fitment
The G5-6128X universal joint dimensional family is widely listed for selected Caterpillar, Komatsu and other construction-machinery driveline applications. References 1S9670 and 145-14-00190 are especially useful when checking equipment parts records. The final application must still be confirmed from the machine serial number, driveshaft assembly, dimensions and wing-bolt arrangement.
Do not identify a G5-6128X universal joint only from the 42.8 mm cap diameter. Models such as 5-6106X and other 42.8×140.4 mm joints may share approximate dimensions while using a different wing style, bolt pattern, pilot feature or retention arrangement. Installing the wrong configuration can prevent proper seating or create driveline movement.
How to Verify Before Ordering
Before ordering a G5-6128X universal joint, measure the cap diameter and full span with a calibrated caliper. Compare the outside pilot, wing profile, bolt-hole diameter, hole-to-hole centres, lug thickness, grease-fitting position and the shape of the mating yoke. Supply photos of all four sides when the old reference is unclear.
During installation, clean the yoke contact surfaces and inspect the bolt holes for wear or elongation. Position the G5-6128X universal joint squarely, use the specified fastener grade and tightening torque, and secure the mounting hardware evenly. After assembly, confirm free articulation, correct running clearance and lubrication according to the machine or shaft manufacturer’s service schedule.
Ordering Information
For a G5-6128X universal joint quotation, send the required quantity, equipment model and serial number, original part reference, measured dimensions and clear photos of the removed joint. MR Driveline can review samples or drawings, compare interchange numbers and discuss packing, production and export delivery requirements before order confirmation.
Frequently Asked Questions
Is 5-6128X the same search reference?
Yes. It is a primary interchange search term for the G5-6128X universal joint, but dimensional and wing-pattern verification is still required.
Are the mounting bolts included?
The product image shows mounting bolts and spring washers. Confirm the final hardware quantity and specification on the quotation.
