What is Angular Contact Ball Bearings and Why Do We Use Them?

NSK's comprehensive range of angular contact ball bearings is designed to meet the ever-evolving requirements of equipment manufacturers.
Angular contact ball bearings feature a contact angle that sustains significant axial loads in one direction at the same time as radial loads.
Since an axial component is generated when radial load is applied, these bearings are typically used in pairs or multi-bearing sets.

Angular contact ball bearings are a type of rolling-element bearing. As the name implies, rolling-element bearings use a roller or ball to carry a load.

There are many types of roller-element bearings, including:

• Needle
• Cylindrical
• Spherical
• Tapered
• Ball

Each type of bearing has its own distinct advantages and trade-offs. To get a better idea about these differences, take a look at the infographic below.

TYPES OF BALL BEARINGS

There are three types of ball bearings: angular contact (which we'll discuss shortly), axial, and deep-groove.

Regardless of the type of ball bearing, their purpose is to reduce rotational friction and all are able to support both axial and radial (or thrust) force.

For reference, bearings move around a fixed axis. Depending on the application, a bearing may be subject to axial force (force that is applied parallel to the axis) or a radial force (force that is applied perpendicular to the axis), or both.

Because not all bearings are able to support both forces, ball bearings are quite versatile and are among the most-used type of rolling-element bearing.

ANGULAR CONTACT BEARINGS

Angular contact bearings are ideal for use in gearboxes, pumps, electric motors, and clutches or other high-speed applications.

They are commonly used in the Materials Handling, Machine Tool, Steel Mill, and Wind Energy industries.

Although angular contact bearings can accept thrust loads in only one direction, they can be manufactured at different contact angles (usually between 0 and 45 degrees) to transfer the load acting upon the bearing.
