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.
Different types and load directions
Deep groove ball bearings are the most common type of rolling bearings. Mainly bear radial load, but also can bear radial load and axial load at the same time. When it only bears radial load, the contact angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of an angular contact bearing and can bear a large axial load. The friction coefficient of the deep groove ball bearing is very small and the limit speed is also high. There is a contact angle between the ring and the ball. The standard contact angles are 15/25 and 40 degrees. The larger the contact angle, the greater the axial load capacity. The smaller the contact angle, the more conducive to high-speed rotation. Single row bearings can withstand Radial load and unidirectional axial load, DB combination, DF combination and double row angular contact ball bearings can bear radial load and bidirectional axial load, DT combination is suitable for large unidirectional axial load and the rated load of a single bearing For insufficient occasions, ACH type bearings are used at high speeds, which have small ball diameters and many balls, and are mostly used for machine tool spindles. In general, angular contact ball bearings are suitable for high-speed, high-precision rotating occasions.
Differences in structure
Deep groove ball bearings and angular contact ball bearings with the same inner and outer diameter and width dimensions have the same inner ring size and structure, but the outer ring size and structure are different.
Deep groove ball bearings have double shoulders on both sides of the outer ring groove, while angular contact ball bearings generally have single shoulders; The curvature of the outer ring of deep groove ball bearings is different from that of angular contact balls, the latter is often greater than the former; The position of the outer ring of the deep groove ball bearing is different from that of the angular contact ball bearing. The specific value of the non-central position is considered during the design of the angular contact ball bearing and is related to the degree of contact angle;
In terms of use
The two uses are different. Deep groove ball bearings are suitable for bearing radial forces, smaller axial forces, combined radial loads and moment loads, while angular contact ball bearings can bear single radial loads and larger shafts. Directional load (different with different contact angles), double paired (different with different matching methods) can bear bidirectional axial load and moment load.
The limiting speed is different. The limiting speed of angular contact ball bearings of the same size is higher than that of deep groove ball bearings.
What Is the Application of Single Row Deep Groove Ball Bearing?
General machinery and electric motors
One of the most common applications for single row deep groove ball bearings is in electric motors and general machinery. Their ability to handle moderate speeds and provide quiet and efficient operation makes them ideal for these applications. They are often found in household appliances, power tools, fans, and other small to medium-sized electric motors.
Automotive industry
In the automotive sector, single row deep groove ball bearings are used in various components such as alternators, starters, clutches, and transmissions. Their robustness and reliability under varying operational conditions make them suitable for automotive applications.
Industrial gearboxes
Gearboxes, which require precise and efficient rotation, often employ single row deep groove ball bearings. Their ability to handle both radial and axial loads efficiently while maintaining low friction is advantageous in these applications.
Pumps and compressors
Pumps and compressors, which are essential components in many industrial processes, also utilize these bearings. They are chosen for their capacity to operate reliably under high radial loads and at varying speed conditions.
Agricultural machinery
In the agricultural sector, equipment like tractors, combines, and other machinery often incorporate single row deep groove ball bearings due to their durability and ability to operate effectively in environments with dust and moisture.
Material handling systems
Conveyor systems and other material handling equipment rely on these bearings for smooth operation. Their ability to support radial loads and handle moderate axial loads is essential in the smooth and efficient movement of materials.
Precision instruments
In precision applications, such as in medical equipment or high-speed machinery, single row deep groove ball bearings are valued for their running accuracy and low noise levels.
Recreational applications
They are also used in recreational applications like skateboards, inline skates, and bicycles, where their compactness and efficiency in handling both radial and axial loads are crucial.
There are several contributing factors which ensure good quality and performance in deep groove ball bearings. Here are some key factors:
Steel grade
The durability and life of the bearings relies on the composition of the steel utilized.
Design conformity
A bearing can perform better if its dimensional accuracy is closer to the design standards.
Grinding
The grinding cycle ensures the smoothness of the bearing's inner and outer ring which is why it needs to be ground over many cycles.
Heat treatments
This process is essential to harden bearings, making them sturdier and long-lasting.
Standard deep groove ball bearings are ABEC 1 , 52100 chrome bearing steel, and are produced in massive quantities in highly automated factories. The components for a ball bearings include inner and outer ring, balls, retainer, seals or shields and grease.
In some cases rings can be made from corrosion resistant materials, balls from ceramic, and cages from plastic or steel or phenolic. Different manufacturers offer seals and shields from various materials. In today's world a bearing can have almost every feature tweaked to obtain the highest level of performance possible for every application.
In addition, quality and tolerance specifications are standardized to conform with ABEC and ISO organizations. These standards define the level of precision and consistency in the bearing's dimensions and rotational accuracy. High-precision bearings meeting the highest standards are essential in applications where minimal noise and vibration are required, such as in high-speed machinery and precision instruments.
Lubrication is chosen based on factors like operational speed, temperature conditions, and environmental exposure. The type of lubricant—whether it's grease, oil, or solid-based—plays a significant role in reducing wear and extending the bearing's service life. Some bearings come with pre-applied lubricants, tailored to provide optimal performance throughout the bearing's lifespan.
Deep groove ball bearings usually come in three forms: open, shielded, and sealed. The choice comes down to the requirements of the application, but more often than not, the sealed type is preferred to enhance their performance and longevity. The shielded and sealed types are commonly known as maintenance-free bearings, a feature that makes them highly attractive for many applications. Deep groove ball bearings often come equipped with various sealing options. Common sealing types include:
Metal Shields
Also known as non-contact sealing, these shields provide moderate protection against contaminants and are suitable for applications with lower contamination risk. Not suitable for water proofing. A metal shield is attached to the outside ring. The inner ring incorporates a V-groove and labyrinth clearance to keep out dirt and seal in the grease.
Rubber Seals
Ideal for environments with high contamination levels, rubber seals provide enhanced protection against dust, moisture, and other external elements. These seals are usually divided into two groups: non-contact, contact. Non-contact rubber seals incorporate synthetic rubber molded to a steel plate in the outer ring. These seals are very good to keep dust and other contaminants out. However, they are not good for water proofing. Contact rubber seals are very similar to non-contact rubber seals, but the edge of these ones is always in contact with the V-groove along the inner ring surface.
