Deep groove ball bearings: types,benefits and manufacturing

The most popular and adaptable form of bearings are deep groove ball bearings. Rolling bearings are a crucial part of every machine element that rotates or oscillates. They assist in transferring weights between various components, including axles, shafts, and wheels, as well as supporting and guiding rotational movement.

A rolling bearing with a ball-rolling component is a ball bearing. This ball has a very small area of contact because it is seated in a ring raceway, or groove. Although there is less friction due to the smaller contact surface, the bearing can only support so much weight. In high-speed, low-load applications, ball bearings are frequently utilised because they have lower friction, noise, and vibration levels, which assist limit unnecessary wear and tear.

Ball bearings generally support loads that are perpendicular to the shaft or radial loads. Even though certain ball bearing types may support axial loads (along the shaft), their carrying capabilities are often quite modest.

What are Deep Groove Ball Bearings?

Deep groove ball bearings resemble conventional bearings but differ in that their raceways nearly match the size of the balls they contain. Compared to shallow-groove bearings, balls with these deep grooves are more stable and able to support greater loads. They continue to offer minimal friction, and the deep groove also reduces noise and vibration while allowing for some axial load capacity.

Chances are, if you’ve ever seen a ball bearing of any kind, it was a deep groove ball bearing. Due to their adaptability, accessibility, and low friction, these bearings are among the most popular. They have various benefits over other ball bearing varieties and are perfect for high rotating speeds.

These bearings are perfect for both domestic and commercial usage because of the enormous variety of designs, sizes, and load-bearing capabilities that they provide. Deep groove ball bearings are also simple to instal in place of conventional bearings, enhancing the machine’s durability and effectiveness.

Types of Deep Groove Ball Bearings

Deep groove bearings now come in a variety of designs thanks to years of design improvement by manufacturers. These kinds are typically more appropriate for a particular application when a deep groove bearing is insufficient.

Single-Row Deep Groove Ball Bearings

This is a standard single track deep groove ball bearing. These are typically strong and constructed of long-lasting materials, extending the service life of the bearings.

There are several varieties of single-row deep groove ball bearings available with bore diameters ranging from 3 mm to 400 mm, making them appropriate for practically any application. Depending on the demands of the customer, certain manufacturers may additionally supply thin, narrow, broad, or small bearings.

Manufacturers also provide ceramic-coated bearings to endure electric pitting and high-temperature units that can survive up to 660 degrees F since deep groove ball bearings must withstand harsh circumstances.

The sensor-bearing unit, which can gauge the condition of the ball bearing components, is one of the most recent advancements in single-row deep groove ball bearings. These straightforward, simple-to-use devices are helpful in electric motors, tractors, conveyors, and road rollers because they aid in speed detection, angular position measurement, and steering.

Sealed Deep Groove Ball Bearings

Sealed deep groove ball bearings are comparable to single-row bearings, with the exception that one or both sides of the bearing have steel or rubber shields added. Grease is pre-applied to these seals to increase the bearing’s lifetime.

In contaminated environments where the bearing’s performance might otherwise be impacted, numerous manufacturers used sealed ball bearings. The shields keep impurities out of the bearing while also assisting the bearing in maintaining grease.

For high-speed applications, larger deep groove ball bearings may even employ machined brass cages, which avoid unintended wear and tear.

Flanged Deep Groove Ball Bearings

A snap ring on ordinary ball bearings functions similarly to the flanged outer ring on some deep groove ball bearings. Due to the simplicity of the housing bore, the flange increases the bearing’s operating efficiency and is also simpler to produce.

The axial stresses found at tube ends or on the rollers of belt guides are ideal for flanged deep groove ball bearings to support. For better axial loads and to accommodate tiny misalignments, some variations even incorporate swivel housing.

Double-Row Deep Groove Ball Bearings

The double-row design maintains the bearing’s low friction properties while enabling a much increased load carrying capability. Because double-row bearings are often just somewhat broader than single-row bearings, they are practically as adaptable and useful.

Although some may be equipped with cages, the fundamental disadvantage of double-row deep groove ball bearings is that they do not come with seals or shields. Although these cages facilitate installation and assembly, they are vulnerable to mechanical pressures when in use. It’s crucial to select the proper cage type for the intended use, especially because some cage materials are delicate to certain lubricants.

Maximum Type Ball Bearings

Compared to their single-row and double-row cousins, these ball bearings feature a lot more rolling components. Higher performance and more accuracy are made possible by these extra balls without compromising lifetime or economy. Depending on the use and specifications, they can be either open or shielded, like single-row deep groove ball bearings.

The Benefits of Deep Groove Ball Bearings

Deep groove ball bearings have several advantages over traditional ball bearings. These include:

Ability to Carry Radial and Axial Loads

The inability of conventional ball bearings to support axial loads is one of their biggest limitations. Although some smaller bearings may only carry around 25% of the radial stress, most deep groove ball bearings can manage about 50% of their radial load in the axial plane. Deep groove ball bearings are incredibly adaptable and well-liked in a range of sectors because to their capacity to support axial and radial stresses.

Low Friction

Deep groove ball bearings are less expensive overall because they produce less friction than ordinary bearings. First of all, it decreases the bearing’s working temperature, extending the bearing’s life. Due to the enhanced efficiency and reduced maintenance needs, using the machinery with the bearing also results in lower operating costs. These bearings are perfect for high rotating situations because of their low friction, which also reduces noise and vibration. They also require less lubrication than their conventional counterparts.

Easy to Install

Because deep groove ball bearings are simple to instal, assembly is streamlined and load capacity is increased. Many manufacturers lower the housing dimensions of machinery by adopting deep groove ball bearings, which results in smaller and lighter assemblies. It is straightforward to switch out inferior ball bearings for deep groove equivalents since deep groove ball bearings also fit in a conventional bearing housing.

Common Uses of Deep Groove Ball Bearings

Ball bearings are used in every spinning component, and due to the advantages of deep groove ball bearings that we have already covered, they are by far the most popular kind of ball bearing.


Deep groove ball bearings are essential components of heavy machinery. They’re particularly useful in:

  • Gearboxes
  • Motors
  • Pumps
  • Construction equipment
  • Engineering machinery
  • Wind turbines
  • Agricultural machinery
  • Mining
  • Machine tools
  • Office equipment
  • Medical devices
  • Food processing machinery
  • Aerospace


These ball bearings are used often in products in your house in addition to their industrial applications. Every appliance with a motor, such as washing machines, dryers, vacuum cleaners, and dishwashers, contains at least one deep groove ball bearing.

Additionally, they may be found in skateboards, pool pumps, and computer fans. Even a fidget spinner toy has several ball bearings that enable it to spin in different directions.

Since the majority of these deep groove ball bearings are shielded, they don’t require ongoing maintenance or lubrication. Some bearings, nevertheless, are open, and by lubricating them properly, one may increase their usefulness and longevity. Ball bearings are inexpensive and simple to replace, which is a blessing.
