Deep Groove Ball Bearings
Deep groove ball bearing has a wide range of sizes and are the most commonly used roll bearings with simple structure, standardized machining process, reliability, durability and high-cost performance. Deep groove bearing can bear axial load in both radial and light axial directions and are easy to install at low maintenance costs.

What Are Deep Groove Ball Bearings?
Known for their versatility, high precision deep groove ball bearing is used in a wide variety of industries. They provide excellent performance and reliability and require little maintenance. They are well suited for anti-corrosion applications. They are also popular in many household appliances, such as vacuum cleaners, dishwashers and computer fans. Deep groove ball bearings can bear radial and axial loads. However, they should not be subjected to heavy loads. Axial loads may increase running noise and shorten bearing service life. The axial load carrying capacity depends on the size and internal structure of the bearing. It is important to use a lubricant that will provide enough grease for the entire life of the bearing. Lithium soap grease is a good choice because of its anti-corrosion properties. It has a mineral oil base.
Deep Groove Ball Bearing vs Angular Contact Ball Bearing
Angular contact ball bearings and deep groove roller bearings have the same structure, which are composed of inner ring, outer ring, rolling elements, and raceways. But these two types of bearings are quite different. Where are the differences?
1. The accuracy is different: the outer raceway surface of angular contact ball bearing is different from that of deep groove ball bearing. The raceways of angular contact ball bearings are not the same high, on one side high and low on the other side. The accuracy of angular contact ball bearings is higher than that of deep groove ball bearings.
2. The load capacity is different: angular contact ball bearings can bear radial and axial forces. Single row deep groove ball bearing can bear radial force while bearing one side’s axial force, so single deep groove ball bearing are generally paired used. Back-to-back, face-to-face arrangement can bear the radial force while bearing the axial force of the double term; and when used in pairs, it can bear double the axial force of one side. Deep groove ball bearings can withstand radial forces, but only a slight axial force.
The rotational speeds of the angular contact ball bearings and deep groove ball bearings are relatively high. The difference between them is mainly due to the different raceway surfaces. The rolling elements of angular contact ball bearings form a contact angle with the raceway surface. According to the different sizes of contact angle which can be divided into 15°, 25°, 40°, etc., the greater the contact angle, the greater the axial force it will bear.
What Are Deep Groove Ball Bearings Used For?
Typically, deep groove ball bearings are used in electric motors, household appliances, tractors, construction machinery, and various other applications. These bearings are available in a variety of styles and sizes. They are designed to withstand radial loads in both directions and provide low friction and vibration. These bearings are commonly used in electric motors, gearboxes and combustion engines.
Single row deep groove ball bearings are available in open or dust-tight designs. These bearings are suitable for high speed operation and are available in a variety of sizes. They can also be equipped with various seals.
Deep groove ball bearings are manufactured with a radial internal clearance CN (standard) table. This clearance is intended to provide proper lubrication. These bearings are lubricated with lithium soap grease, which has good corrosion protection properties.
Features of Deep Groove Ball Bearing
High radial load
The outer ring with high wall thickness can not only withstand high radial load, but also reduce deformation and bending stress when working as a roller.
Withstanding overturning moment
Double row deep groove ball bearings can withstand greater overturning moment compared to single-row ball roller bearings.
Long service life
The convex design of the outer ring surface can be greatly improved to cope with the possible inclination of the outer ring on the working track surface, or where the edge stress needs to be minimized.
Easy to Install
Deep groove ball bearings are easy to install, which leads to simplified assembly and higher load capacity.
Types of Deep Groove Ball Bearing
"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."
– Single-Row 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."
– Sealed Deep Groove Ball Bearings
"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. The flange improves the bearing’s running efficiency and is also easier to machine due to the simplicity of the housing bore."

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 groove ball bearing 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 deep groove ball bearing application, especially as some cage materials are sensitive to specific lubricants.
Thin Section Deep Groove Ball Bearing
"Extremely economical, withstand high load-ratings, and are suitable for temperatures from circa -10°C up to +120°C, in case of rubber seals up to circa +100°C in the long run. The rolling bearing steel is wear-resistant, shock-resistant, conductive, and magnetic."
– rolling bearing steel
"Are hygienic, corrosion-resistant, mostly lubricated with grease for the food industry, offers high load-ratings, is magnetic, and is admissible for a temperature range from circa -20°C up to +120°C, in case of rubber seals up to +120°C in the long run."
– stainless steel
"They are extremely wear-resistant by their great hardness, corrosion-resistant and durable. They have good emergency running characteristics, are lighter than steel bearings of the same size, are suitable for a dry run, are current insulating, and non-magnetic. "
