Why Use Deep Groove Ball Bearings?

Deep groove ball bearings are the most widely used bearing type and are particularly versatile. They have low friction and are optimized for low noise and low vibration, resulting in high speeds. They carry radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types. 

 

Deep Groove Ball Bearing

 

What are deep groove ball bearings?

 

Deep groove ball bearings have a groove near the outside and inside of the bearing. These grooves reduce the strain near the bearing, so they can carry heavier loads and operate at high speeds.

 

Types of deep groove ball bearings

Over the years, manufacturers have improved the design of deep groove bearings, resulting in several different types. These types are often better suited for specific applications where deep groove bearings are not suitable.

 

Single row deep groove ball bearings

These are typically single race deep groove ball bearings. They are typically robust and made of durable materials, ensuring that these bearings have a longer service life.

 

Single row deep groove ball bearings are also subdivided into other types with bore diameters ranging from 3 mm to 400 mm, making them suitable for almost any application. Some manufacturers also offer thin, narrow, wide or miniature bearings depending on the customer's needs.

 

Because deep groove ball bearings are subjected to extreme conditions, manufacturers also offer ceramic coated bearings to handle electrical pitting and high temperature devices that can withstand up to 660 degrees Fahrenheit.

 

One of the latest developments in single row deep groove ball bearings is the sensor bearing unit, which measures the condition of the ball bearing components. These units are simple to use and can help with speed sensing, angular position measurement and steering, making them available for use in electric motors, tractors, conveyors and road rollers.

 

Double-row deep groove ball bearings

The double-row design allows significantly higher load carrying capacity while still maintaining the low friction characteristics of the bearing. Double-row bearings are usually only slightly wider than single-row bearings, which makes them almost as versatile and practical.

 

The main disadvantage of double row deep groove ball bearings is that they do not have seals or shields, although some may be equipped with cages. These cages facilitate mounting and assembly, but are susceptible to mechanical stress during operation. Selecting the correct type of cage for a particular application is critical, especially since some cage materials are sensitive to specific lubricants.
