TIMKEN® METRIC TAPERED ROLLER BEARINGS

TIMKEN® METRIC TAPERED ROLLER BEARINGS PART-NUMBERING SYSTEMS METRIC PART-NUMBERING SYSTEMS Width series Diameter series Bore code Tapered roller bearing Diameter series Angle series Bore diameter (mm) Width series The original metric part-numbering system for tapered roller bearings was based on the ISO 15 dimensional plan for radial bearings. ISO introduced a new numbering system for tapered roller bearings in the ISO 355 plan. This numbering system uses three alphanumeric fields to define a dimension series. The bearing part number is defined by adding the inner ring bore diameter after the...
