Deep Groove Ball Bearings, or Deep Groove Radial Ball Bearings, are essential components in various types of machinery. Designed to enable smooth and efficient operation with little maintenance, Deep Groove Bearings are characterised by deep raceway grooves inside the inner and outer rings. The design of Deep Groove Ball Bearings allows them to accommodate both radial and axial loads in both directions, making them versatile for use in a wide range of applications. Deep Groove Radial Ball bearings can withstand high-speed rotations and are available in many designs, sizes, and variants. They are the most commonly used bearing type, serving applications in multiple industries worldwide. Deep Groove Ball Bearings play a crucial role in maintaining smooth and reliable mechanical operations, whether used in electric motors, gearboxes, engines, machine tools, or endless equipment applications. We stock a range of metric and imperial Deep Groove Ball Bearings from world-renowned brands such as SKF, FAG, NSK and Timken. Discover our range of Radial Ball Bearings below.

Frequently Asked Questions
What is a Deep Groove in a Radial Ball Bearing?
A deep groove in a Radial Ball Bearing refers to the design of the inner and outer raceways (also referred to as races or rings), which have a deep concave spherical profile matching the profile of the balls' surface. This design provides a larger contact area, allowing the bearing to handle higher axial and radial loads. Deep Groove Ball Bearings are versatile and commonly used in automotive and industrial machinery.
Why use a deep groove ball bearing?
Deep Groove Ball Bearings are widely used due to their versatility and ability to support both radial and axial loads. Their simple design, featuring a deep raceway, allows for smooth and quiet operation with minimal friction. Deep Grooves are suitable for high-speed applications making them ideal for use in multiple applications.
What load type is a Deep Groove Ball Bearing?
Deep Groove Ball Bearings handle both radial and axial loads. They are suitable for high-speed applications and are commonly used in industries like automotive and industrial machinery due to their ability to manage mixed load types efficiently. Radial ball bearings operate at high speeds with low friction. Known for durability, they minimise wear and reduce maintenance costs.
What is the difference between a thrust ball bearing and a radial ball bearing?
Thrust ball bearings support axial loads parallel to the shaft and are used where the primary load is along the axis of rotation. Radial ball bearings, on the other hand, handle radial loads perpendicular to the shaft and can also manage some axial loads. Radial bearings are suited for high-speed applications, while thrust ball bearings are specialised to provide axial load support.
