At Emerson Bearing, we are deeply committed to our customers and take great pride in delivering high-quality products along with accurate performance documentation. Our bearings are engineered and manufactured with precision and adhere to the highest quality standards. However, no bearing is indestructible. So, how can you ensure your bearing performs reliably throughout its lifespan?
Rolling element bearings are generally known for their reliability and often outlast the machines they're installed in. However, several factors can reduce their lifespan. The most common causes of early failure are excessive load and speed. A load that exceeds the bearing's specifications can accelerate fatigue and potentially shorten its life by a factor of 8–10. Similarly, operating speeds that go beyond the recommended limits can drastically reduce bearing life. Other contributing factors include extreme temperatures, vibrations, and contamination from dirt or debris.
That said, if a bearing is properly selected for its intended application, it should last the expected lifetime—or even longer. Below is an approximate range of operating hours you might expect for different applications:
- Hobbyist power tools: 100–150 hours
- Professional power tools: 100–1000 hours
- Household appliances: 200–3000 hours
- Agricultural machinery: 500–5000 hours
- Tractors: 5000–12,000 hours
- Cars and trucks: 800–10,000 hours (trucks typically have longer-lasting bearings)
- Hydraulic systems: 1000–20,000 hours (stationary systems tend to last longer than mobile ones)
- Office and data processing equipment: 1200–16,000 hours
- Material handling equipment: 2000–18,000 hours
- Rolling mills: 2000–20,000 hours
- Compressors: 3000–20,000 hours
- Building material machinery: 5000–50,000 hours
- Crushers: 13,000–40,000 hours
- Extruders: 20,000–50,000 hours
- Industrial gearboxes: 20,000–50,000 hours
- Textile machinery: 20,000–70,000 hours
- Printing presses: 35,000–100,000 hours
- Paper machinery: 75,000–150,000 hours
