Bearing Life and Reliability Comparison Test on YBN bearings and A Well-known Brand Bearings

Put the two brands of bearings on the professional bearing life strengthen tester (ABLT-3) for comparison test. As shown in the figure left, set 1KN of radial load and 500N of axial load, and operate continuous for 1000 hours at 15000RPM. Then to disassemble these bearings then analysis, and got the results as follow:

YBN bearing rings and steel balls are “zero-wear”, as follow figures.After the test, the outer ring raceway, inner ring raceway and steel ball all didn’t appear wear, which is “zero-wear”

The inner rings and outer rings of a well-known brand bearing appear raceway spalling and steel ball early failure. As follow figures. After the test, the outer ring raceway, inner ring raceway and steel ball all appear obvious spalling failure phenomenon.

The secret of YBN bearings is because of the Customized Lubricant Selection. Selecting suitable lubricants is also a part of the comprehensive support. We have developed our own range of rolling bearing greases from a variety of lubricants. The greases are tested with state-of-the-art testing procedures and systems. They offer superb prerequisites for long bearing operating life and operating safety.
