As for the maximum value for inner and outer ring diameters of bearings whose bearing numbers are marked with "+" (inner ring) and "++" (outer ring), the precision class is an integer for class 4 and class 2 bearings only. Bearings with a # symbol next to the serial number are J-series bearings, and have a different tolerance to other series. For more details, see “Bearing Tolerance” listed in the “NTN ‘Ball and Roller Bearings’ Catalog.”

Nodes have NTN 4T-HM813844/HM813810 bearings in stock. Tapered roller bearings (Inch series), are designed so the inner and outer ring raceway and the apex of the tapered rollers intersect at one point on the bearing centerline.
