Picture this: your excavator is digging a foundation pit when suddenly the boom jams. The site falls silent. Workers stand idle. Within just two hours, you’ve lost $5,000 in downtime.
How can a small part bring an entire machine to a halt? The answer lies in the health of your excavator’s bearings.
Unlike standard bearings used in cars or household tools, heavy equipment bearings are engineered to handle extreme loads, vibrations, and outdoor conditions.
Track system – bearings keep the undercarriage moving smoothly under tons of weight.
Boom and arm joints – they absorb shock and ensure precise digging movements.
Swing system – swing bearings allow the upper structure to rotate safely and efficiently.
Without these construction machinery bearings, an excavator simply cannot function.
(Insert simple line diagram: key bearing locations in an excavator.)
Unusual noise: grinding or knocking sounds during operation.
Overheating: joints feel hot after short use.
Stiff movement: the boom, bucket, or swing feels jerky.
Small excavators: every 2,000–3,000 working hours.
Medium excavators: every 3,000–5,000 hours.
Large excavators: 5,000+ hours, depending on workload.
