Frequently Asked Questions

What does a swing bearing do on a Case excavator?

The swing bearing is the slewing ring that connects the upper structure to the undercarriage and supports full 360-degree house rotation under load. When it wears out, the house can bind, wobble, or make noise during rotation. Broken Tractor carries new and used swing bearing assemblies across Case 9000 series and CX series excavators.

How do I find the right swing bearing for my Case CX210?

Match your machine to the correct part number, since Case CX210 excavators use different swing bearings depending on the exact model variant. For example, we carry KRB1347 for the CX210 and KRB11710 for the CX210B, CX210C, and CX210D. Confirm your model and serial range before ordering so you get the correct assembly.

Do you have swing bearings for the Case 9040 and 9040B?

Yes, Broken Tractor carries separate swing bearings for these models. The Case 9040 uses part number 150775A1, and the 9040B uses 159424A1. Because the assemblies differ, verify your exact model before ordering.

Will one swing bearing fit all Case CX130 machines?

No, the CX130 family uses more than one swing bearing depending on the variant. We carry KNB10130 for the CX130 and KMB10410 for the CX130B, CX130C, CX130D, and CX135SR Tier III. Match the part number to your specific machine to be sure it fits.

Are these swing bearings new or used?

Broken Tractor offers both new and used swing bearing assemblies, depending on the model and what is available. Condition can vary by part number, so confirm the fitment for your model and serial range with the parts team before ordering. Call (800) 909-7060 if you need help verifying the correct assembly.
