Discover more about the Deep Groove Ball Bearings range.
Deep groove ball bearings are a type of radial bearing designed to support both radial and limited axial loads. These precision components feature raceways with a deeper groove than standard bearings, allowing them to handle higher loads and operate at higher speeds with reduced friction. Their versatility and reliability make them a popular choice across rotary applications from robotics and electric motors to machinery and suspension systems.
How Single Row Deep Groove Ball Bearings Work
Single row deep groove ball bearings function by using hardened steel balls that roll between the inner and outer raceways. The deep groove design enables uniform load distribution, reducing stress on individual components and improving overall lifespan.
Available in single row configurations, deep groove ball bearings are used for supporting radial loads while also accommodating axial loading in both directions. Their low friction coefficient ensures quiet, efficient rotation, making them ideal for high-speed applications.
Materials Deep Groove Ball Bearings Are Made From
Accu utilises advanced precision engineering materials to ensure our Deep Groove Single Row Ball Bearings deliver optimal performance and longevity, even in the most challenging applications.
- Stainless Steel - (440): A high-grade metal offering excellent corrosion resistance and durability, making it ideal for both rigorous industrial and precision settings.
- Steel - (AISI 52100): A high-strength alloy engineered for maximum load-bearing capacity and fatigue resistance, providing a cost-effective and reliable solution for high-speed, heavy-duty applications.
- Plastic - POM: A robust thermoplastic distinguished by its high stiffness, low friction and dimensional stability, offering a reliable, lightweight alternative for precision mechanical assemblies.
- Plastic - Xirodur: Paired with Stainless Steel A4 balls, this specification provides a lightweight solution tailored for specialised environments where traditional metals may not suit.
Sizes and Types of Radial Deep Groove Ball Bearings Available
Our selection of radial deep groove ball bearings is available in a wide range of dimensions and shielding options to suit your diverse mechanical project requirements:
- Inside Diameter: 1mm to 50mm
- Outside Diameter: 3mm to 240mm
- Shield Types: Open, for environments where easy inspection and re-lubrication are needed. Sealed for protection against contamination and to reduce maintenance. Shielded offers some protection while maintaining lower friction than sealed variants.

FAQs
Q: Why use deep groove ball bearings?
A: When used in your projects, deep groove ball bearing advantages provide high load capacity, low friction and quiet operation, making them suitable for high-speed and precision applications. For projects with limited space, explore our range of thin-section bearings.
Q: What is the difference between deep groove and normal ball bearings?
A: Deep groove bearings have deeper raceways, which allow them to handle higher radial and axial loads compared to standard ball bearings.
Q: How long should a deep groove ball bearing last?
A: Lifespan depends on load, speed and operating environment, but under optimal conditions, they can last thousands of hours.
Q: Do deep groove ball bearings create a lot of noise?
A: No, they are designed for smooth, quiet operation, especially when properly lubricated and installed into a project.
Q: Can a deep groove ball bearing take radial load?
A: Yes, they are primarily designed for radial loads but can also accommodate limited axial loads in both directions.
Q: What are some examples of deep groove ball bearing applications?
A: Deep groove bearings are widely used in applications requiring smooth, high-speed rotation and load handling. Common examples include electric motors, gearboxes, pumps, fans, conveyors, robotics, automotive wheel hubs and industrial machinery.
Their versatility and low-maintenance design make them suitable for both precision instruments and heavy-duty mechanical systems.
Q: Deep groove ball bearings vs angular contact bearings, which should I use?
A: Choose deep groove bearings for applications primarily requiring radial load support with moderate axial loads in both directions. They are ideal for high-speed, low-friction environments.
Opt for angular contact bearings when your application demands higher axial load capacity in one direction or combined radial and axial loads. Their rolling elements support greater rigidity and precision under axial stress, commonly used in machine tool spindles and high-performance assemblies.
