Application Overview

Bearing positions on Construction Machinery

KOYO Bearing Supplier supplies Koyo / JTEKT bearings for Construction Machinery by matching each replacement to the machine model, bearing position and original specification — not to dimensions alone.

Excavators, wheel loaders and other earthmoving equipment depend on bearings in wheel ends, final drives, swing and travel mechanisms, and heavy-duty shafts. These positions carry high radial and axial loads, shock from digging and loading, and contamination from mud, water and abrasive dust. Fleet operators and maintenance contractors need the correct rollers and cups for each wheel end and fast supply to limit downtime on site.

  • Use tapered roller bearings or wheel hub units on wheel ends, and set them to the preload given in the equipment manual.
  • Specify spherical roller bearings for heavy shafts where misalignment or frame flex can occur.
  • Order the cone and cup as a matched set for each wheel end, so mixed wear surfaces are not reused.
  • For fleets across several job sites, group bearings by machine and position on one list to avoid wrong quantities.

Machine model plus position is often enough to identify the reference.

FAQ

Sourcing bearings for Construction Machinery: common questions

What should I send if the bearing markings are worn?

Send the machine model, the bearing position and clear photos of whatever markings remain. Measured dimensions and a photo of the bearing as installed help close the gap, and the reference is confirmed before the quote is issued.

Can I include the machine part number from the parts manual?

Yes. Machine part numbers are checked together with the model and position to identify the matching Koyo / JTEKT reference. A page from the manual or your repair parts list works as well.

Can you quote all the bearings for a gearbox or wheel-end rebuild?

Yes. A single position or the complete assembly can be quoted on one enquiry. Listing the mating parts up front avoids a second shutdown and a repeat order.
