AST Introduces the Heavy-Duty Bearing Line

SPHERICAL PLAIN BEARINGS TACKLE TOUGH APPLICATIONS

Spherical Plain Bearings serve in applications such as Off-Highway Vehicles, Agricultural and Mining Equipment, and Robotics.

Five basic types of bearings are offered:

1. Standard Radial heavy radial and thrust loading, designed to accommodate misalignment.
Features: Heavy radial Loading, Accomodates midalignment, thrust loading, and Non-separable.

2. Extended Inner Ring designed to eliminate locational spacers.
Features: Eliminates locational spacers.

3. High Misalignment features a cross section specifically to accommodate greater misalignment.
Features: Heavy cross section, Accomodates greater misalignment.

4. Angular Contact for unidirectional thrust and combination loads.
Features: Single acting-for unidirectional thrust and combination loads.

5. Self-lubricated low maintenance with Teflon, dry film, or injection molded polymer lubrication.
Features: Teflon, dry film or injection molded polymer lubrication for low maintenance.

Standard features include fractured, sold or two-piece outer rings, two or three-piece metal-to-metal constructions, open or sealed versions and maintenance free lining. Available in sizes 0.5-12 inch and 4-300 Metric. Custom sizes are available

At a time where some major bearing manufacturer's are having trouble supplying Tapered Roller Bearings within reasonable delivery times, this is very good news for the heavy-duty machinery Industry. AST Bearings provides quality Tapered Roller Bearings with quick delivery times with a product that is completely interchangeable with those of major bearing manufacturers all at a cost-effective price.

These 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 difference is Through-Hardened has a consistent hardness throughout the component and Case-Hardened has a surface hardening combined with a tough, flexible core. Case Hardened will be supplied upon special request only.

The advantages of these tough Tapered Roller Bearings is they 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, Gear Box, 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. Custom sizes are also available upon special request. Please consult an AST sales specialist for larger sizes and availability.
