What Are Angular Contact Ball Bearings?

Angular contact ball bearings are designed with raceways that have an angle of contact, allowing them to support significant thrust loads in one direction while also accommodating radial loads. This makes them ideal for applications where both types of loads are present, such as pumps, compressors, and machine tool spindles.

Understanding the Different Series

Choosing the right angular contact ball bearing series depends on the specific demands of your application. Here’s a breakdown of the series we offer and their typical uses:

Angular Contact Ball Bearing 52 Series

The 52 series angular contact ball bearings are double-row bearings designed to handle moderate radial and axial loads. They are commonly used in applications where space is limited and high stiffness is required.

• Typical Uses: Pumps, gearboxes, and general industrial machinery.

Angular Contact Ball Bearing 53 Series

Similar to the 52 series, the 53 series angular contact ball bearings are also double-row bearings. However, they are designed to handle heavier loads and provide even greater stiffness.

• Typical Uses: Heavy-duty pumps, gearboxes, and applications requiring high rigidity.

Angular Contact Ball Bearing 70 Series

The 70 series angular contact ball bearings are single-row bearings known for their high precision and speed capabilities. They are often used in applications where accuracy and high rotational speeds are critical.

• Typical Uses: Machine tool spindles, high-speed machinery, and precision instruments.

Angular Contact Ball Bearing 72 Series

The 72 series angular contact ball bearings are also single-row bearings, offering a balance between load capacity and speed. They are suitable for a wide range of applications requiring both radial and axial support.

• Typical Uses: Electric motors, pumps, and general industrial machinery.

Angular Contact Ball Bearing 79 Series

The 79 series angular contact ball bearings are high-precision, single-row bearings designed for extremely high speeds and light loads. They are often used in precision spindles and other applications where minimal heat generation and high accuracy are essential.

• Typical Uses: Precision spindles, grinding machines, and high-speed testing equipment.

How to Select the Correct Series

Selecting the correct angular contact ball bearing series involves considering several factors:

1. Load Requirements: Determine the radial and axial loads the bearing will need to support.
2. Speed Requirements: Consider the operating speed of the machinery. High-speed applications require bearings with low friction and high precision.
3. Precision Requirements: Evaluate the level of accuracy needed for the application. Machine tool spindles, for example, require high-precision bearings.
4. Space Limitations: Consider the available space for the bearing. Double-row bearings like the 52 and 53 series are suitable for applications with limited space.
5. Operating Environment: Take into account the operating temperature, lubrication requirements, and potential exposure to contaminants.

Real-World Examples

• Machine Tool Spindles: The 70 series angular contact ball bearings are frequently used in machine tool spindles due to their high precision and speed capabilities.
• Pumps: The 52 and 72 series bearings are commonly used in pumps to handle both radial and axial loads.
• High-Speed Machinery: The 79 series bearings are ideal for high-speed machinery requiring minimal heat generation and high accuracy.
