This type of bearing is equipped with a circular table-shaped roller. The roller is guided by the large rib of the inner ring. The apex of each conical surface of the inner ring raceway surface, the outer ring raceway surface and the roller rolling surface is designed to intersect the bearing center line. On the one point, single-row bearings can withstand radial loads and one-way axial loads. Double-row bearings can withstand radial loads and two-way axial loads. They are suitable for withstanding heavy loads and shock loads, depending on the contact chest (α). It is divided into three types: small cone angle, medium cone angle and large cone angle. The larger the contact angle is, the larger the axial load capacity is. The outer ring and inner component (inner ring and roller and cage assembly) can be separated for easy loading. The bearings of the rear auxiliary code "J" or "JR" are internationally interchangeable, and the bearings are also used in the British series.

Mainly applicable cages: steel stamping cages, synthetic resin forming cages, pin cages.

Main use: Automobile: front wheel, rear wheel, transmission, differential pinion shaft. Machine tool spindles, construction machinery, large agricultural machinery, railway vehicle gear reduction devices, rolling mill roll necks and reduction gears.
