What is tapered roller bearings?

Tapered roller bearings are separatable formed bearings , They have taper-formed raceways on the outer rings , and have taper-formed rollers between raceways . These bearings can accommodate radial-axial applicable for withstandjing heavy loads and impact loads

Types of tapered roller bearing

Tapered roller bearings are produced in many designs and sizes to match their many uses. These can be grouped as follows:

1.single row tapered roller bearings.

2.paired single row tapered roller bearing

3.double row tapered roller bearings.

4.four-row tapered roller bearings

These are described in four separate sections under the appropriate headings.

manufactures sealed, greased and pre-adjusted units based on tapered roller bearings, such as

tapered bearing units for railbound vehicles

Design features
Tapered roller bearings have tapered inner and outer ring raceways between which tapered rollers are arranged. The projection lines of all the tapered surfaces meet at a common point on the bearing axis. Their design makes tapered roller bearings particularly suitable for the accommodation of combined (radial and axial) loads. The axial load carrying capacity of the bearings is largely determined by the contact angle ±; the larger ±, the higher the axial load carrying capacity. An indication of the angle size is given by the calculation factor e; the larger the value of e, the larger the contact angle and the greater the suitability of the bearing for carrying axial loads.

Tapered roller bearings are generally separable, i.e. the cone, consisting of the inner ring with roller and cage assembly, can be mounted separately from the cup (outer ring).

Applications of taper roller bearings

Taper Roller Bearings are widely used in the industrial field ,such as rubber ,plastics . texitile . papermaking. Food , electrical home applicances , chemical industry . peroleum , generating electriciry , cement , mine ,steel and automobiles ,etc .
