Frequently Asked Questions

What are the signs of a bad swing bearing on an IHI excavator?

The most common signs of a worn swing bearing on an IHI excavator are excessive play in the upper structure, grinding noise during rotation, uneven swing movement, and visible bearing wear. If your machine shows any of these symptoms, replacing the swing bearing can bring back smooth, full rotation of the house.

What does the swing bearing do on an IHI mini excavator?

The swing bearing is the upper-structure slewing ring that connects the house to the undercarriage. It carries the upper structure and allows it to rotate, so wear in this part shows up directly as play or rough, uneven swing.

What swing bearing fits an IHI 9VX or 9VX3 excavator?

Broken Tractor offers a swing bearing, SKU 0605429UA, that fits both the IHI 9VX and 9VX3 excavators. Matching the SKU to your model before ordering helps make sure you get the right part.

Do the IHI 25VX3 and 25JX use the same swing bearing?

No, the IHI 25VX3 and 25JX use different swing bearings. SKU 0605428UA fits the 25VX3 along with the 28N2 and 28N3, while SKU 60540554 fits the 25JX. The IHI 20VZ also has its own swing bearing, SKU 60540816.

Which IHI excavator models does Broken Tractor carry swing bearings for?

We carry IHI excavator swing bearings across a wide range of models, from the 9VX mini series up through the 100NS and 135NS. Because several generational variants are covered within each series, confirm your exact model suffix before ordering, such as 55VX versus 55VX3 or 45UJ versus 45UJ-2.
