NBC Spherical Roller Bearings 21306 CC W33 to SP72X25X17 Ultra High Speed Angular Contact Ball Bearings and aerospace sectorsSpherical Roller Bearings are a type of rolling element bearing designed to handle heavy radial loads and moderate axial loads even when theres misalignment between the shaft and housing. Part Description Inner Ring Has two raceways that are inclined at an angle to the bearing axis. Outer Ring Has a single spherical raceway this allows the rollers to align themselves automatically. Rollers Barrel shaped (spherical) rollers positioned between the inner
