1. Spherical Roller Bearing
   Spherical roller bearings have double row rollers, the outer ring has one shared spherical raceway, and the inner ring has two raceways that are inclined at an angle relative to the bearing axis. Spherical roller bearings have cylindrical and conical inner bores. Conical taper tapers are 1:30 and 1:12. These conical bore bearings are fitted with adapter sleeves or withdrawal sleeves. Spherical roller bearings are generally coded 2 (21300/22000/22300/23000/23100/23200/23900/24000/24100/24200)
