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.
