Single Row Angular Contact Ball Bearings
AMIGO Single row angular contact ball bearings can accommodate axial loads in one direction only and are typically adjusted against a second bearing. Their bearing rings have an upper and a lower shoulder and are non-separable.
- High load carrying capacity
The lower shoulder enables a large number of balls to be incorporated in the bearing, giving it a relatively high load carrying capacity. - Good running properties
Rapid accelerations and decelerations are possible. - Easy mounting of universally matchable bearings
No adjustment is needed for correct internal clearance or preload.
Single row angular contact ball bearings are widely used in various industries. Their availability matches their versatility across numerous applications in a wide range of designs, variants, and sizes. Examples of applications include:
- Industrial pumps
- Compressors
- Material Handling
- Electric motors

Frequently Asked Questions (FAQs)
Q: How do single row angular contact ball bearings differ from other types of bearings?
A: Unlike other bearings, single row angular contact ball bearings are optimized for combined axial and radial loads. Their raceways are arranged at an angle, enabling better axial load handling compared to deep groove ball bearings.
Q: What materials are used in single row angular contact ball bearings?
A: These bearings are typically made from high-quality steel for durability and performance. In some cases, stainless steel is used for applications requiring corrosion resistance, such as in harsh environments.
Q: Can single row angular contact ball bearings handle axial loads in both directions?
A: No, single row angular contact ball bearings are designed to handle axial loads in one direction only. To manage loads in both directions, they are often used in pairs or sets.
Q: What are the common applications of single row angular contact ball bearings?
A: These bearings are commonly used in machine tool spindles, pumps, gearboxes, and other high-speed, precision applications where both radial and axial loads are present.
Q: What are the advantages of single row angular contact ball bearings?
A: The main advantages include their ability to handle combined loads, high-speed capability, and precise performance in demanding applications. They are also compact and offer efficient load distribution.
Q: What is the significance of the contact angle in single row angular contact ball bearings?
A: The contact angle affects the bearing’s ability to handle axial loads. A larger contact angle increases the axial load capacity, while a smaller angle improves high-speed performance.
Q: How should single row angular contact ball bearings be mounted?
A: They are typically mounted in pairs or sets to handle bidirectional axial loads. The mounting arrangement (e.g., back-to-back or face-to-face) depends on the load distribution and operational requirements.
Q: How do I choose the right single row angular contact ball bearing for my application?
A: Selecting the right bearing involves considering load capacities, speed requirements, precision, and the application’s environmental conditions. Consulting with a bearing expert or manufacturer can help ensure the best choice.
Q: Are single row angular contact ball bearings suitable for high-speed applications?
A: Yes, these bearings are designed for high-speed applications. Their low friction and precise load distribution make them ideal for use in demanding environments such as machine tools and automotive systems.
