Tapered Roller Bearings The rollers of this type of bearing are spherical. Since the groove surface of the washer is spherical, it is capable of self-aligning to a certain extent allowing the shaft to have a certain inclination. Tapered roller bearings have a very large axial load capacity, which can bear a certain degree of radial load while bearing axial loads (but the radial load should not exceed 55% of the axial load). axis). So this kind of bearing is mainly used for hydraulic generators, vertical shaft motors, ship propeller shafts, tower cranes, extruders and so on. This bearing is generally not suitable for high speed rotation. Lubricating oil is often used when in use.
The international designation of this type of bearing usually has 5 codes starting with the number 2.
The old international designation for this type of bearing usually had 7 codes starting with 9.
