AST Bearings announces its high carbon chromium steel tapered roller bearings to complement its existing line of quality products.

AST Bearings provides quality tapered roller bearings with a product that is completely interchangeable with those of major bearing manufacturers.

Bearings are comprised of four basic components: The cone (inner ring), the cup (outer ring), tapered rollers and a cage (roller retainer). The cone, cup and rollers carry the load while the cage spaces and retain the rollers on the cone.

The cone, rollers and cage are referred to as the cone assembly. Individual cup and cone components are available as well as the complete assembly.

Although through-hardened bearings have gradually become the preference in heavy-duty commercial trucking applications, AST Bearings will supply both through hardened and case hardened tapered roller bearings. The through-hardened has a consistent hardness throughout the component and the case hardened bearings has a surface hardening combined with a tough, flexible core.

Both categories of tapered roller bearings offer dimensional stability under heavy loads, long life performance in harsh and contaminated environments, a durable steel cage and are dimensionally interchangeable with other major bearing manufacturers products.

Tapered roller bearings are used for heavy-duty, moderate speed applications. Typical applications that will benefit from these durable bearings is agriculture, construction and mining equipment, various axle systems, conveyance vehicles, gearbox, engine motors, reducers and more.

A broad range of inch and metric sizes are available. The standard stock sizes are: ID 15-240mm or .59-9.45 inches to OD 35-40mm or 1.38-15.75 inches. Most standard industrial sizes are available in inch and metric.
