The following table contains the dimensions for 6mm inner diameter ball bearings. In the table, SS represents stainless steel material, F represents flanged bearings, and the rest are made of chrome steel. ZZ indicates shielded (dust cover) bearings. For chrome steel, the ZZ shield is made of SPCC material, while for stainless steel, it is made of AISI304 material. 2RS represents rubber seals made of NBR material.
For small-size matching, use this chart together with CXE Bearing collections for stainless miniature ball bearings, metric ball bearings, and stainless steel bearings; those pages provide a cleaner path from dimensions to related products.
