What is a Deep Groove Ball Bearing?

 Back to FAQ

Deep groove ball bearings are the most common type of ball bearing. They are commonly used in electric motors and in household appliances, car motors, office machinery, automation control, and garden and household tools. They have deep raceway grooves and their race dimensions are close to the dimensions of the balls that run inside.

Deep groove ball bearings come in many sizes, materials and varieties according to consumer needs, including special industrial uses such as high-temperature applications. High-temperature bearings are made to withstand temperatures up to 350°C (660°F) and are suitable for machines used in the metals industry or for industrial ovens.

They fall under two designs: there are single-row deep groove ball bearings with a single row ; and there are double-row bearings, which have two rows of bearing balls. They can also be made in different sizes and for different loads according to their application, from miniature ball bearings for light loads and small assemblies to large deep groove ball bearings and heavy load deep groove bearings.

Replacing deep groove ball bearings with plain bearings can offer a range of benefits, including lower cost, less maintenance, greatly reduce noise at low speeds and easier installation. Plain bearing can also have a higher load capacity, simplified assembly, increased longevity, reduced housing dimensions and assembly size and weight.
