Deep Groove Ball Bearings.

What are Deep Groove Ball Bearings?

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's deep groove single row ball bearings are manufactured exclusively from high-grade stainless steel (440), offering excellent corrosion resistance and durability in demanding environments, ideal for both industrial and precision settings.

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: 3mm to 25mm
• Outside Diameter: 8mm to 62mm
• Shield Types: Open, for environments where easy inspection and re-lubrication are needed. Sealed, for protection against contamination and reducing 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.
