Frequently Asked Questions
What does a swing bearing do on a Link-Belt excavator?
The swing bearing is the slewing ring that supports the upper structure and lets the cab and boom assembly rotate a full 360 degrees. It is critical to safe, efficient excavator operation. Broken Tractor carries swing bearings for Link-Belt excavators ranging from the compact 130LX up to 400-class machines.
Which swing bearing fits a Link-Belt 3400Q TL excavator?
The Link-Belt 3400Q TL uses swing bearing SKU KBB0667. The standard Link-Belt 3400Q is listed with a different bearing, SKU KBB0413, so be sure you know which version you have before ordering. Matching the SKU to your exact model is the easiest way to get the right bearing.
Is the Link-Belt 4300Q swing bearing the same as the LS-4300C-II swing bearing?
No, they are listed as different parts. The Link-Belt 4300Q uses SKU KSB0713, while the LS-4300C-II uses SKU KSB0339. Because fitment can depend on model and serial number, match the part number from your old bearing or confirm with our parts team at (800) 909-7060 before ordering.
Do you carry swing bearings for Link-Belt forestry and material handler excavators?
Yes, Broken Tractor offers swing bearing SKU KSB0946 for the Link-Belt 350X2 Forestry, 360X2 MH, 370LX Forestry and 370X2 MH. These specialty machines have their own bearing listing, separate from the standard excavator models. Check your model designation carefully to make sure you order the forestry or MH version.
What swing bearing fits a Link-Belt 2800Q or 290 LL excavator?
The Link-Belt 2800Q uses swing bearing SKU KRB1090, and the Link-Belt 290 LL uses SKU KBB0816. We also carry SKU KNB11840 for the Link-Belt 130LX. If your machine has had parts changed over its life, compare the part number on your existing bearing before ordering.
