 Tapered Roller Bearing

Tapered roller bearings have inner and outer ring raceways and tapered rollers arranged in between. Conical surface of the projection lines of all are the same point on the bearing axis together. Tapered roller bearing is mainly exposed to the radial diameter, axial load. Load carrying capacity depends on the angle of the outer ring raceway, the greater the angle the greater the carrying capacity.

Tapered roller bearings are designed such that their conical rollers and raceways are arranged so that all elements of the roller and raceway cones meet at a common apex on the bearing axis. The rollers are guided by the contact between the large end of the roller and the rib on the inner ring (cone). This construction provides a high capacity for radial loads, axial loads, and combined loads. The larger the contact angle, the greater the loading capacity becomes. When a pure radial load is placed on the bearing, an induced load in the axial direction is also generated. So, these bearings are generally used in pairs opposing each other. Tapered roller bearings have the inherent advantage of being adjustable and, they can be set to approach optimum performance in almost any application.
