Single Row Angular Contact Ball Bearings (General)

Q: How do I choose the right contact angle when buying?

Consider your load ratio and speed. Higher axial load component suggests a larger angle (e.g., 40°). Higher speed requirements favor a smaller angle (e.g., 25°). Consult product detail pages.

Q: How long will it take to ship after the payment?

We have sufficient inventory. Most orders will be shipped within 10 days or less. After the order is dispatched, you can track the logistics information at any time until the goods are signed for.

Supports Combined Loads Efficiently

Single row angular contact ball bearing is a basic type of bearing, designed to accommodate both radial and significant axial loads simultaneously, but only in one direction for a single bearing.

The internal geometry features offset raceways creating a contact angle, enabling this crucial capability. This makes them an ideal choice for applications where both load types are present and need reliable management, such as in pumps and compressors.

Select these when simple radial bearings aren’t enough.

Variety of Contact Angles Available

These angular contact bearings are available with different standard contact angles (commonly 15°, 25°, 30°, 40°). Different contact angles result in different performance: larger angle provides higher axial load capacity but generally lower speed capability, while smaller angle offers higher speed potential but lower axial capacity.

Choose the contact angle that best balances the axial load magnitude and operational speed requirements for your specific machinery, ensuring optimal performance and lifespan.

Versatile Choice Among Bearing Types

As a widely used type of bearing, single row angular contact ball bearings offer a versatile solution for many industrial applications like gearboxes, electric motors, and machine tool components where combined loads occur.

While a double row angular contact ball bearing offers bidirectional axial support in one unit, single row bearings provide more flexibility in arrangement and preload control. They represent a reliable and cost-effective choice for numerous standard engineering challenges.

FREQUENTLY ASKED QUESTIONS

Why can a single bearing only take axial load one way?

Because the internal raceways are offset relative to each other, creating an angle. Load is transmitted along this angle, meaning axial force can only be properly supported in one direction based on how the bearing is oriented.

What's the main difference between single row angular contact ball bearings vs. double row angular contact ball bearing?

A single row bearing has one row of balls and handles axial load in one direction (when used alone).

A double row angular contact ball bearing has two rows, typically arranged internally like a DB pair, handling bidirectional axial loads in a single, more compact unit.

How do I choose the right contact angle when buying?

Consider your load ratio and speed. Higher axial load component suggests a larger angle (e.g., 40°). Higher speed requirements favor a smaller angle (e.g., 25°). Consult product detail pages.
