F623-2RS Flanged Bearing ABEC-7 pack of 10
The F623-2RS flanged bearing ABEC-7 have a flange on the outer part of the wheel. These bearings come with a rubber seal on both sides to prevent dust or debris from entering and come prepacked with grease for continuous smooth operation.
The ABEC scale is an industry accepted standard for the tolerances of a ball bearing. It was developed by the Annular Bearing Engineering Committee (ABEC) of the American Bearing Manufacturers Association (ABMA). The ABEC scale is designed to provide bearing manufacturers dimensional specifications that meet the standards of precision bearings in a specified class. Manufacturers who produce equipment that require bearings must also know the dimensional tolerances to design parts that will accommodate a bearing.
There are five classes from largest to smallest tolerances: 1, 3, 5, 7, 9. The higher ABEC classes provide better precision, efficiency, and the possibility of greater speed capabilities.
