TAPERED ROLLER BEARINGS

Overview

Tapered roller bearings have tapered inner and outer ring raceways, with tapered rollers arranged in between. All conical surface projection lines meet at the same point on the bearing axis. This design makes tapered roller bearings especially suitable for combined radial and axial loads.

These bearings are separable. The inner ring together with the roller and cage assembly can be installed separately from the outer ring.

Based on the number of rows, they are divided into single row, double row and four row tapered roller bearings.

Features

- The bearing can be separated. The inner ring with roller and cage assembly can be installed separately from the outer ring.

- Roller and raceway contact along a contact line, which helps reduce stress concentration.

- Tapered roller bearings can withstand high radial and axial loads.

- They can only take axial load in one direction. To handle axial load from the opposite direction, you need to install another tapered roller bearing arranged symmetrically.

- These bearings mainly carry combined radial and axial loads. Load carrying capacity depends on the outer ring raceway angle. The greater the angle, the higher the capacity.

- Most of the axial load capacity is determined by the contact angle α. As the angle α increases, the axial load capacity goes up. The angle size is shown by the calculation factor e. The larger e is, the greater the contact angle, and the better the bearing handles axial load.

- For single row tapered roller bearings, the user must adjust the clearance during installation.

- For double row and four row tapered roller bearings, the clearance is set at the factory according to user requirements. No adjustment is needed by the user.

Applications

- Single row tapered roller bearings are used in the largest quantity.

- In recent years, small sized double row tapered roller bearings have been used in car front wheels.

- Four row tapered roller bearings are used in large scale cold rolling mills and other heavy machines.

- Tapered roller bearings are widely used in automotive, rolling mills, mining, metallurgy, plastics machinery and many other industries.
