Tapered roller bearings

Tapered roller bearings consist of four interdependent components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer. The taper angles allow the bearing to handle a combination of radial and thrust loads. The steeper the cup angle, the greater the ability of the tapered roller bearing to handle thrust loads.

Single-Row Tapered Roller Bearings 

The most basic and widely used tapered bearing, the single-row type consists of the cone assembly and the cup. It is usually fitted as one of an opposing pair. During equipment assembly, single-row bearings can be set to the required clearance (endplay) or preload condition to optimize performance.

Single-row tapered roller bearings have positive roller alignment that ensures true rolling motion and generates a “seating force” that pushes the roller against the cone large rib. This seating force prevents the rollers from skewing off apex, thereby keeping them positively aligned and located against the cone large rib.

Double-Row Tapered Roller Bearings 

Double- or two-row tapered roller bearings feature double cups and two single cones. They are available in a variety of configurations for general industrial and automotive applications.

Four-Row Tapered Roller Bearings 

Four-row bearings provide maximum capacity in minimum space, combining the inherent high-load, radial/thrust capacity and direct/indirect mounting variables of tapered roller bearings.

Their main application is on the roll necks of rolling mill equipment.  All four-row bearings are supplied as pre-set matched assemblies with all components identified to ensure correct installation sequence.
