Deep groove ball bearing
Deep groove ball bearings are among the most widely used type of bearing in the world. They can operate at high speeds and can carry radial and (limited) axial loads. They are commonly used in electric motors, compressors, fans, and conveyors.
WHAT ARE THE BENEFITS OF DEEP GROOVE BALL BEARINGS?
Versatility – because they can carry radial and axial loads, they have a wider range of applications for many industries
Cost savings – deep groove ball bearings create less friction torque. This lowers operating temperature (which extends the life of the bearing) and reduces energy cost of running equipment (such as conveyor belts).
Less upkeep – because of their simple design, low operating temperature, and low friction, deep groove ball bearings have a longer expected shelf life than other bearings. They do not require additional lubrication after installation, which also means less maintenance downtime.
WHAT INDUSTRIES USE DEEP GROOVE BALL BEARINGS?
MANY INDUSTRIES BENEFIT FROM THE USE OF DEEP GROOVE BALL BEARINGS:
Agricultural
Food Processing
Machine Tool
Material Handling
Medical / Pharmaceutical
Printing
Railway and Transportation
Wind Energy
Types of Deep Groove Ball Bearings
Manufacturers have refined the design of deep groove bearings over the years, resulting in several different types. These types are usually better suited to a specific application where a deep groove bearing isn’t suitable.
Single-Row Deep Groove Ball Bearings
This is the typical deep groove ball bearing that has a single raceway. These are usually robust and made from durable materials, ensuring that these bearings have an extended service life.
Single-row deep groove ball bearings are also subdivided into other types, ranging from 3 mm to 400 mm bore sizes, suitable for almost any application. Some manufacturers will also offer thin, narrow, wide, or miniature bearings depending on clients’ needs.
Since deep groove ball bearings need to withstand extreme conditions, manufacturers also offer ceramic-coated bearings to handle electric pitting and high-temperature units that can withstand up to 660 degrees F.
One of the latest developments in single-row deep groove ball bearings is the sensor-bearing unit, which can measure the status of the ball bearing components. These units are simple and easy to use and can help with speed sensing, angular position measuring, and steering, making them useful in electric motors, tractors, conveyors, and road rollers.
Sealed Deep Groove Ball Bearings
Sealed deep groove ball bearings are similar to single-row bearings, except that they have steel or rubber shields installed on one or both sides of the bearing. These seals are pre-lubricated with grease to extend the lifespan of the bearing.
Many manufacturers used sealed ball bearings in contaminated environments that may otherwise influence the performance of the bearing. The shields help the bearing retain grease while also preventing any contaminants from entering the bearing itself.
Larger deep groove ball bearings may even use machined brass cages for high-speed applications, where the cage prevents unwanted wear and tear.
Flanged Deep Groove Ball Bearings
Some deep groove ball bearings come with a flanged outer ring, which works similarly to a snap ring on standard ball bearings. The flange improves the bearing’s running efficiency and is also easier to machine due to the simplicity of the housing bore.
Flanged deep groove ball bearings are excellent for bearing axial loads, such as in tube ends or on belt guide rollers. Some variants even have swivel housing to allow for slight misalignments and better axial loads.
Double-Row Deep Groove Ball Bearings
The double-row design allows for a significantly higher load carrying capacity while still retaining the bearing’s low friction characteristics. Double-row bearings are usually just slightly wider than their single-row counterparts, making them almost as versatile and practical.
The main drawback of double-row deep groove ball bearings is that they do not come with seals or shields, though some may be fitted with cages. These cages assist with installation and assembly but are susceptible to mechanical stresses during operation. It’s vital to choose the right type of cage for the specific application, especially as some cage materials are sensitive to specific lubricants.
Maximum Type Ball Bearings
These ball bearings have many more rolling elements than their single and double-row counterparts. These additional balls allow for higher performance and higher precision without sacrificing efficiency or longevity. Like single-row deep groove ball bearings, they can be either open or shielded, depending on the application and requirements.
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
One of the most considerable drawbacks of traditional ball bearings is their inability to bear axial loads. Most deep groove ball bearings can handle around 50% of their radial load in the axial plane, though some smaller bearings can only handle around 25% of the radial load. This ability to bear axial and radial loads makes deep groove ball bearings extraordinarily versatile and has made them popular in a wide variety of industries.
Low Friction
Deep groove ball bearings create less friction than standard bearings, which translates to cost savings in several ways. Firstly, it lowers the operating temperature of the bearing, which extends the lifespan of the bearing. It also makes it cheaper to operate the machinery with the bearing due to increased efficiency and lowered maintenance requirements. Low friction also results in lowered noise and vibration, making these bearings ideal for high rotational environments, where they will use less lubrication than their traditional counterparts.
Easy to Install
Deep groove ball bearings are easy to install, which leads to simplified assembly and higher load capacity. Many manufacturers take advantage of the benefits of deep groove ball bearings and reduce the housing dimensions of machinery, which leads to smaller and lighter assemblies. Deep groove ball bearings also fit in a traditional bearing housing, which makes it simple to replace traditional ball bearings with their superior counterparts.
Common Uses of Deep Groove Ball Bearings
Every spinning part uses a ball bearing, and thanks to the benefits of deep groove ball bearings that we’ve discussed, they are the most common type of ball bearing.
Industrial
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
Residential
These ball bearings aren’t just limited to industrial uses; they’re also common components of items in your home. Any appliance with a motor has at least one deep groove ball bearing, including washing machines, dryers, vacuum cleaners, and dishwashers.
They’re also found in computer fans, pool pumps, and even skateboards. Even a fidget spinner toy consists of multiple ball bearings that allow the toy to spin in multiple directions.
Most of these deep groove ball bearings have a shielded design, meaning they don’t need constant lubrication or care. However, some are open, and adding some appropriate lubricant can extend the bearing’s lifespan and effectiveness. Luckily, ball bearings are also cheap and easy to replace, if necessary.
Versions of deep groove ball bearings
Single row
Main dimensions according to DIN 625-1. Favourable "all-round bearing". Versatile.
Double row
Main dimensions according to DIN 625-3. Considerably higher load carrying capacity than single row bearings at a slightly greater width
Deep groove ball bearings with a flanged outer ring
For simplified locating bores in which the bearing is supposed to be axially fixed.
With slot and snap ring
Suitable for the form-fitting axial fixing of the bearing in a bore.
Full complement ball set
Without a cage and maximum number of balls, higher load carrying capacity than caged deep groove ball bearings of the same size.
