Factors affecting the service life of rolling bearings

Our bearing design and the highest level of precision manufacturing, and uphold the highest standards of quality, but, bearing performance is not always the case. So how can you determine your bearing to perform well throughout the process?

Rolling is very reliable, even more than installed on the machine. However, there are several factors that can shorten the life of rolling bearings, load and speed are the most common cause of early failure. It will withstand the rated load exceeds a speed of fatigue and shorten its life up to 8-10 times faster than the steering specification and will significantly reduce bearing life. Other factors such as extreme temperatures, vibration, dirt or contaminants and play an important part in bearing wear.

However, if a bearing is properly selected and used for the right machine, it can certainly continue to use the specified lifetime (possibly longer).

Listed below are the bearing life approximation (at run-time measurement), for different machines:

Fans 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: 800-10000 hours
Trucks generally longer than the bearing life vehicles
Hydraulic system: 1000-20000 hours
In the stationary hydraulic systems bearing general than mobile hydraulic systems Bearings
Office and data processing equipment: 1200-16000 hours
Material Handling Equipment: 2000-18000 hours
Rolling mill: 2000-20000 hours
Compressor: 3000-20000 hours
Building Material Machinery: 5000-50000 hours
Crusher: 13000-40000 hours
Extruder: 20000-50000 hours
Industrial Gearbox: 20000-50000 hours
Textile Machinery: from 20,000 to 70,000 hours
Press: 35000-100000 hours

Paper Machinery: 75000-150000 hours
