749A/742 3.25×5.909×1.75″ Timken Tapered Roller Bearing Timken

Timken offers the most extensive line of tapered roller bearings available anywhere in the world.

Tapered roller bearings are uniquely designed to manage both thrust and radial loads on rotating shafts and in housings. We manufacture nearly 26,000 tapered roller bearingcombinations – in single, double and four-row tapered roller bearing configurations. Customized geometries and engineered surfaces can be applied to these tapered roller bearings to further enhance performance in demanding applications.

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

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.
