Angular Contact Ball Bearing Supplier
Choose high-performance angular contact ball bearings for precision manufacturing and industrial applications with high axial load stresses. As a leading angular contact ball bearing supplier in North America, we offer a wide range of bearing specs, sizes, and configurations, including single row, double row angular contact ball bearing, precision angular contact ball bearing, and angular contact thrust ball bearing options, with corrosion-resistant cage materials and specialized lubricants available. Angular contact ball bearings are ideal for demanding industrial environments and can extend the uptime of machinery, automated equipment, and tight-tolerance systems.
The Design of Angular Contact Ball Bearings
Two main factors give angular contact ball bearings their outstanding performance capabilities. The first is the open-ended shape of the ring enclosure. One ring shoulder is fully enclosed, but the opposite side is either completely or partially open. This allows for a larger ball in comparison to the rest of the bearing, significantly increasing the load strength.
The other factor is the angle of contact. Common contact angles for these bearings range from 15 degrees up to 40 degrees. Lower angles aren't as steep as deep groove bearings, which allows for higher RPM and superior axial load, while higher contact angles are typical of an angular contact thrust ball bearing built for maximum axial load capacity. The only downside is that single row angular contact ball bearings can only handle axial load in one direction. For this reason, they are commonly used in pairs, or as a double row angular contact ball bearing, to handle loads in both directions.
Types of Angular Contact Ball Bearings We Supply
Handle combined radial and one-directional axial loads. Commonly used where loads run predominantly in a single direction, such as pumps and gearboxes.
A double row angular contact ball bearing combines two rows of balls in a single unit, allowing it to support radial loads and axial loads in both directions. This design saves axial space compared to mounting two single-row bearings back-to-back and is well suited for compact housings that still need bidirectional thrust capacity, common in gearboxes, pumps, and automotive steering assemblies. For deeper specs on this configuration, see our double row ball bearings page.
A precision angular contact ball bearing is manufactured to tighter ABEC/ISO tolerance classes for dimensional accuracy, runout, and rotational precision. These are the preferred choice for high-speed spindle applications such as CNC machine tool spindles, aerospace components, and other equipment where maintaining tight tolerances at high RPM is critical. For super precision-grade options, see our super precision ball bearings page.
An angular contact thrust ball bearing is used specifically where axial (thrust) load capacity is the primary requirement, such as ball screw support, vertical shaft mounting, and equipment with significant one-directional or reversing thrust loads. These bearings are frequently used in matched sets (back-to-back, face-to-face, or tandem) so that thrust loads from both directions can be managed reliably.
Pre-matched sets mounted back-to-back (DB), face-to-face (DF), or in tandem (DT) configurations to fine-tune preload, stiffness, and load direction for a specific application. This is a common configuration for angular contact thrust ball bearing installations carrying heavy or reversing axial loads.
Design & Performance Benefits
Two design factors give angular contact ball bearings their performance advantage: the open-ended shape of one ring shoulder (allowing a larger ball diameter for greater load strength) and the contact angle itself, which determines how axial vs. radial load is distributed.
| Benefit | What It Means for Your Application |
|---|---|
| Combined load handling | Supports radial and axial loads at the same time |
| High axial/thrust capacity | Angular contact thrust ball bearing designs manage heavy one-directional or reversing thrust loads |
| High-speed capability | Handles greater operating stresses and high RPM applications |
| Tight tolerances | Precision engineering supports accurate dimensions and load distribution |
| Configurable contact angle | Optimize for maximum speed or maximum axial load capacity |
| Advanced lubrication options | Improves cooling and extends bearing service life |
| Corrosion-resistant cage options | Better performance in harsh or washdown environments |
Contact Angle Options
| Contact Angle | Best Suited For |
|---|---|
| Low angle (∼15°) | Higher speed, lower axial load capacity |
| Medium angle (∼25°) | Balanced radial/axial load capacity |
| High angle (∼30 to 40°) | Angular contact thrust ball bearing applications requiring maximum axial load capacity |
Choosing the right angular contact ball bearing depends on the degree of axial load, desired fit, thermal expansion considerations, and whether vibration dampening is needed. Applications with dominant thrust loading typically call for a higher contact angle, which is why 40° angular contact thrust ball bearings are among the most common configurations in vertical and high-thrust equipment.

Family-owned since 1991, Baker Bearing combines three decades of industry experience with the inventory depth and shipping speed manufacturers rely on when downtime isn't an option.
A deep groove ball bearing primarily supports radial loads with limited axial load in either direction, while an angular contact ball bearing is specifically designed with offset raceways to carry combined radial and axial loads in one direction, offering greater axial load capacity.
Not exactly. A pure thrust bearing is designed to handle axial load only, with little to no radial load capacity. An angular contact thrust ball bearing, by contrast, uses an angled raceway design that carries substantial axial (thrust) load along with radial load and rotational speed capability, making it a better fit for applications that combine shaft rotation with heavy thrust, such as ball screws and vertical shaft equipment.
A double row angular contact ball bearing is a good choice when you need bidirectional axial load support in a compact axial space. It performs the job of two single-row bearings mounted back-to-back, but in a single, more compact unit, useful in gearboxes, pumps, and steering assemblies.
A precision angular contact ball bearing is manufactured to tighter dimensional and rotational tolerances (often ABEC 5, 7, or 9 / ISO P4, P2 classes), making it suitable for high-speed spindle and aerospace applications where accuracy at high RPM is critical.
Lower contact angles (around 15°) favor higher speeds, while higher contact angles (30 to 40°), typical of an angular contact thrust ball bearing, favor greater axial load capacity. A Baker Bearing specialist can help match the correct angle to your specific load and speed requirements.
Yes. As an angular contact ball bearing supplier, Baker Bearing carries products from SKF, Timken, FAG, Barden Precision Bearings, Kaydon, Koyo, NSK, NTN, and other leading manufacturers, with over 6 million parts in stock for fast delivery.
