SKF bearings are usually limited in terms of space and their size is limited. In most cases, the diameter of the shaft (or SKF bearing bore diameter) is dimensioned in advance according to the machine's design specifications. Therefore, the type and size of SKF bearings must be determined according to SKF, and the bore diameter must be the same as the diameter of the shaft. All SKF bearings are designed according to the diameter of the standard bore determined by the International Standards Organization. SKF bearings have a wide range of standardized bearing types and sizes to meet the installation dimensions of many mechanical equipment. It is for this reason that SKF bearing sizes are limited to international standard dimensions, and only in this way can the user unit easily and quickly select the right accessories for the machine. Through a specific SKF bearing application, SKF bearing dimensions fixed in these bearings can usually be found. Of course, there are some special equipment that use special size bearings, which are outside the SKF bearing size limit, and this bearing is usually called "non-standard bearing".
