64xx single row deep groove ball bearing
Description
Six thousand four hundred (6400) series single row deep groove ball bearings are among the most commonly used bearing series. The bearing consists of a four-digit identification number, the first two of which are always "64". The second pair of digits can range from 00 (in theory) to 99 and shows the nominal diameter (shaft size) of the bearing's inner ring.
Other features of the 6400 series bearings are identified by signs or suffixes. The most common markings for 6400 series bearings are: SS=stainless steel, TN=polyamide basket, M=bronze basket, Z/ZZ=metal dust cover, RS/2RS=plastic dust cover. You can find more information in their catalogs by clicking on the DOWNLOADABLE DOCUMENTS tab. In our online store, the selection of miniature single-row deep groove bearings with serial number 64x (marked with three digits) is also listed among the bearings of the six thousand four hundred series.
