*Measures the anderon value in an assembled bearing.*Detects slight surface irregularities arising from machining imperfections and other factors.*Detects displacement in a radial direction caused by rolling surface irregularities.*Provides the “anderon” value, a numerical expression of the degree of vibration and noise in the bearing, allows quantitative assessment of bearing performance.*Enables the discovery of the causes of vibrations (scratches on the raceways of outer and inner races made during machining, scratches on ball surfaces, contamination by dust particles, etc.).*Enables the sorting of bearings by precision class and more accurate assessment of bearing quality.*Development of high-quality products: aids in the development of high-quality, durable bearings that generate minimal vibration and noise.*Assurance of product quality: allows data to be gathered that can be used for objective assessment of quality, particularly vibration and noise characteristics.*Optimal management of products by quality: High-sensitivity detection of minute but critical variations in product characteristics, allowing to sort bearings accurately by quality for optimal product management.*Improved productivity: allows inspection of bearings before installation in high-precision, high-performance products susceptible to vibration, minimizing defects in assembled products and improving productivity.*Optimal parts control in the open market environment: permits high-accuracy acceptance inspections of delivered parts, allowing to test various samples obtained from both domestic and overseas manufacturers to help secure parts that offer optimal quality.
