Matched Pair Bearings
Matched Pair bearings are Angular contact ball bearings that are suitable for applications that require high accuracy and high-speed performance. Bearings with a smaller contact angle are more suitable for high-speed rotation; those with a larger contact angle are more suitable for high load applications. Angular contact ball bearings are often preloaded to enhance their rigidity and rotating performance. For high-precision matched pair angular contact ball bearings of class 5 or higher, which are used in machine tools and other precision equipment, the standard preload is specified in three levels: light, medium, and heavy. Two bearings are used together facing one another or two or more bearings are matched and used.
