The SKF bearing catalog is organized by bearing construction. Deep groove ball bearings, angular contact bearings and self-aligning ball bearings have separate lines; roller bearings are divided into cylindrical, tapered, spherical and CARB designs. There are also thrust bearings, needle roller bearings and Y inserts. This organization lets you start with the assembly’s function before comparing part numbers.
If you have a removed part, first locate its complete designation. Preserve letters, slashes and any final block together with the basic number. Bore diameter alone does not distinguish every construction. Each line page brings together its references and helps relate the marking to the mounting arrangement; dimensions should be checked against the part and the equipment drawing.
For a request, specify the shaft and bearing position to examine. Include quantity, photographs of the markings, bore diameter, outside diameter and width. If the arrangement uses a housing, a sleeve or another bearing, identify those components separately. This describes the part within its assembly instead of treating every reference in the category as interchangeable.
