How To Choose the Right Bearing for Your Application
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 to the highest standards of precision, ensuring reliability and durability. However, even the best bearings have a finite lifespan. So, how can you ensure your bearing performs optimally throughout its life?
Rolling element bearings are generally very reliable and often outlast the machines they're installed in. That said, several factors can reduce their service life. The most common causes of early failure are excessive load and speed. If the load exceeds the bearing's specifications, it can significantly accelerate fatigue and potentially reduce the bearing’s life by up to 8–10 times. Similarly, exceeding the recommended speed can drastically shorten the bearing’s operational life. Other influencing factors include extreme temperatures, vibrations, and exposure to dirt or contaminants.
Despite these challenges, when a bearing is correctly selected for its intended application, it should perform as expected—often lasting beyond its projected lifespan. Below is an approximate range of operating hours you can expect for different types of applications:
- Hobbyist power tools: 100–150 hours
- Professional power tools: 100–1000 hours
- Household appliances: 200–3000 hours
- Agricultural machinery: 500–5000 hours
- Tractors: 5000–12000 hours
- Cars and trucks: 800–10,000 hours (trucks typically last longer)
- 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
