Frequently Asked Questions

How do I choose the right Komatsu excavator swing bearing replacement?

Match the OEM part number for your exact model and generation, because Komatsu swing bearings change between series and frame versions. Broken Tractor lists each swing bearing by its OEM part number, such as 201-25 series for PC60 and PC70 models or 207-25 series for PC300 models, along with the models it fits. Some models, like the PC200-6, appear under more than one part number, so fitment can depend on serial number. If you are unsure, call our parts team at (800) 909-7060 to confirm before ordering.

Which swing bearing fits a Komatsu PC300 excavator?

It depends on the generation of your PC300. Part number 207-25-51100 fits the PC300-5, PC300LC-5, PC300LC-5K and PC300HD-5K. Part number 207-25-61100 fits the PC300-6, PC300LC-6, PC300LL-6, PC300-7, PC300LC-7, PC300-8 and PC300LC-8, as well as PC350 and PC360 models.

What swing bearing do I need for a Komatsu PC200 excavator?

Broken Tractor carries several PC200 swing bearings, each matched to a different generation. Part number 205-25-00023 fits the PC200-3, 20Y-25-11103 fits the PC200-5, and 20Y-25-21100 or 20Y-25-21200 fit PC200-6 machines. Part number 206-25-00200 covers the PC200-7 and PC200-8 versions, though the PC200-7 is also listed under 20Y-25-21200, so match the part number on your existing bearing or confirm with the parts team.

Do you carry swing bearings for Komatsu wheeled excavators?

Yes, Broken Tractor offers swing bearings for Komatsu PW wheeled excavators. Covered models include the PW95-1, PW98MR-3, PW98MR-6, PW140-7K, PW148-8, PW150-1, PW170-5K, PW180-7K and PW210-1. Each one is listed by OEM part number, so check the part number against your machine before ordering.

Do you have swing bearings for Komatsu mini excavators and large excavators?

Yes, Broken Tractor carries swing bearings across a wide size range of Komatsu excavators. Smaller models include the PC12R-8, PC15MR-1, PC18MR-2, PC30-7, PC40-7 and PC45MR-1.
