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 ball bearings can bear axial load in both radial and light axial directions and are easy to install at low maintenance costs.

They have low friction torque and are optimized for low vibration and low noise, which are suitable for high-speed operation.

Deep Groove Ball Bearing vs Angular Contact Ball Bearing

Angular contact ball bearings and deep groove ball 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 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."

Common Uses

Electric motors and generators, agriculture, material transportation, industrial gearboxes, food and beverage, industrial pumps, industrial fans, medical devices, two and three-wheelers,cars and light trucks, etc.

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.

Thin Section Deep Groove Ball Bearing

Thin section deep groove ball bearings are mainly used in space-limited working conditions. Such bearings are available in both open and closed configurations.
