In addition to bearings with cylindrical bore, the above NTN spherical roller bearings are available with tapered bore too, they are specified by attaching the suffix K to the end of the bearing’s basic number. But for the bearing in series 241 and 240, the suffix K30 indicates the tapered ratio for the bearing is 1: 30.
