Tapered roller bearings are bearings that can take large axial loads, making them excellent thrust bearings, and are also able to sustain large radial forces.

Design and Structure
The tapered roller bearing has tapered inner and outer ring raceways, between which the tapered rollers are arranged. The projection lines of the raceways meet at the same point on the bearing axis. This design provides a true rolling and low friction, making the precision bearing suitable for combined radial and axial loads.

Most tapered roller bearings are separable, as they consist of the tapered inner ring assembly with rollers and cages, as well as a tapered outer ring. Both parts can be mounted individually.

Available Variations
We supply single row tapered roller bearings, double-row tapered roller bearings, and four-row roller bearings, all of which are standard variations.

Applications
The tapered roller bearing is commonly used in automobiles, rolling mills, mining equipment, metallurgical equipment, and plastic machinery, among other uses.
