Taper roller bearing size chart
Metric taper roller bearing dimensions for the 30200, 30300, 31300, 32000 and 32200 series.
These are the standard ISO dimensions for single row metric taper roller bearings. d is the bore of the cone, D is the outside diameter of the cup and T is the total width of the assembled bearing.
Bearings with the same bore and OD can have different widths and contact angles (for example 30205, 32205 and 33205), so always match the full number. For inch-size cone and cup sets such as 25580/20, read both numbers from the old bearing; see the full taper range.
