Tapered bearings consist of four interdependent components: the cone (inner ring), cup (outer ring), tapered rollers (rolling elements) and cage (roller retainer). Double- or two-row tapered roller bearings 350000 series features double cups and two single cones, which is assembled with two inner ring parts of single row tapered roller bearing in back-to-back arrangement on the unitized outer ring. This 350000 series double row tapered roller bearings have glass-fiber reinforced polyamide cages as a basic design, and some cages are made from pressed steel.
Since the inner clearance is set for the bearing itself by design, its operation as well as its mounting can be carried out uniformly without much adjustment, and this is why it is used for automotive hubs and others to maintain optimum performance considering their sizes and functions. These bearings can be divided into two groups, one with seals and the other without seals.
This type of bearing is available as a TDO(double outer race), or a TDI(double inner race), and normally supplied with spacers to provide a pre-adjusted assembly. It can handle radial load and axial load in either direction.
Application
Widely used in front and rear wheels, transmissions, different pinion, railroad, construction, agricultural equipment, rolling mill equipment, gear boxes, machine tool spindles and other industries.
