Construction Equipment Fleets

Construction fleets use bearings in haul truck wheel ends, final drives, undercarriage components and auxiliary drives. Dust, mud, shock loads and long shifts make these positions critical wear items. Fleet managers look for correct fit, predictable service life and enough matched parts to complete a repair without a return trip.

• Specify sealed or shielded bearings where abrasive dust and mud can reach the raceways and the design allows it.
• Check seal and shaft surfaces at each bearing change, because damaged seals quickly let contamination back in.
• Confirm heat-related requirements on wheel ends and drives subject to long duty cycles or heavy braking.
• Prepare a parts list by machine model and position when several units in the fleet need the same service.
