As in the past, all SKF Explorer roller bearings have been uprated with an increase of 15% in dynamic load rating. Tapered roller bearings can tolerate large amounts of axial force as there is a larger contact area than with a spherical bearing. The classification and designation of tapered roller bearings in metric sizes is based on: This conical geometry creates a linear contact patch which permits greater loads to be carried than with spherical (ball) bearings, which have point contact. 2.Double Row Tapered roller bearings are rolling element bearings that can support axial forces (i.e., they are good thrust bearings) as well as radial forces. The classification and designation of tapered roller bearings in inch sizes is based on: ANSI/ABMA 19.2:2013 (prefixes K and AK). Because an axial component of force is produced when this type of bearing is loaded radially, two or more bearings are matched and used together. For a tapered roller bearing 32207 for example, (older generation has 15 rollersand the next-generation has 17 rollers), with 2 additional rolls of a larger size, the gain in dynamic capabilities is 34%. In general, the tapered roller bearing outer ring and inner component within the size range involved are 100% interchangeable. 98.425 mm, Width 30.958 mm Tapered Roller Bearing 53177-53387X-TIMKEN, Inner diam. The larger the half angles of these cones the larger the axial force that the bearing can sustain.
