Deep Groove Ball Bearing vs Angular Contact Ball Bearing
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 angular contact ball bearings can bear radial force while bearing one side’s axial force, so single row angular contact ball bearings 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.
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 ball roller 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 Bearings
"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."

"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 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.
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. "
