Tapered roller bearings feature tapered rollers as well as tapered raceways for both the inner and outer rings. These types of roller bearings are constructed with four basic components, namely the inner ring (referred to as the cone), the outer ring (referred to as the cup), the tapered-shaped rollers, and a cage to retain the rollers. This type of construction enables the accommodation of combination loads, allowing dual-acting loads and radial loads simultaneously. Additionally, tapered roller bearings reduce both friction and generated heat.
Tapered roller bearings offer a wide range of benefits for industrial applications. For example, their capability to evenly transfer loads while rolling has positively reduced wear and tear, providing remarkable durability. Their longer service life has further reduced the need for maintenance. The cone and cup assembly of a tapered roller bearing makes it ideal for supporting combined loads, and at the same time provides low friction, dimensional stability, and optimum reliability in heavy-duty operations. These unique advantages of tapered roller bearings have facilitated their extensive application in transmission shafts and rotating axles.
The tapered roller bearings are primarily used in applications that demand increased performance and reduced friction. Their typical applications include heavy-duty and moderate-speed equipment, such as:
