Ball Bearings

A ball bearing is a kind of rolling bearing. The ball is installed between the inner ring and the outer ring and can bear a large load. While promoting movement, it has three main functions: load-bearing, friction reduction, and positioning of moving machine parts.

Ball bearings are mainly composed of four essential elements: ball, inner ring, outer ring, and retainer, also called cage or retainer. General industrial ball bearings meet AISI 52100 standards. Balls and coils are usually high chromium steel, with Rockwell C-scale hardness between 61-65. The hardness of the retainer is lower than that of balls and rings, and its materials are metal (such as medium carbon steel, aluminum alloy) or non-metal (such as Teflon, PTFE, polymer materials). Ball bearings have lower rotational frictional resistance than journal bearings, so the temperature generated by friction will be lower at the same speed.

Types of Ball Bearings

Deep Groove Ball Bearing: Deep groove ball bearings are the most common type of rolling bearings. Deep groove ball bearings are composed of an outer ring, an inner ring, a set of steel balls, and cages. There are two types of deep groove ball bearings, single row, and double row. The deep groove ball structure is also divided into two types: sealed and open. The open type refers to the bearing without a sealed structure.

Thrust Ball Bearing: Thrust ball bearings are designed to withstand thrust loads during high-speed operation and are composed of washer-shaped ferrules with the ball rolling raceway grooves. Because the ring is in the shape of a cushion, thrust ball bearings are divided into flat base cushion type and self-aligning spherical cushion type. In addition, this kind of bearing can bear axial load but cannot bear radial load.

Angular Contact Bearing: Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e., simultaneously acting radial and axial loads.

Miniature Ball Bearings: Miniature ball bearings are deep groove ball bearings in small. Their dimensions make them suitable for special applications. In addition, they allow very high speeds with low noise.

Self Aligning Ball Bearing: Self-aligning ball bearings have two structures: cylindrical bore and tapered bore, and the cage is made of steel plate, synthetic resin, etc. Its characteristic is that the outer ring raceway is spherical, with self-alignment, which can compensate for the errors caused by misalignment and shaft deflection. Still, the relative inclination of the inner and outer rings should not exceed 3 degrees.

linear Ball Bearing: Linear bearing is a kind of linear motion system used for linear stroke and cylindrical shaft. Because the bearing ball is in point contact with the bearing jacket, the steel ball rolls with the least frictional resistance. Therefore, the linear bearing has low friction, is relatively stable, does not change with the bearing speed, and can obtain smooth linear motion with high sensitivity and accuracy.

The consumption of linear bearings also has its limitations. The most important thing is that the impact load capacity of the bearing is poor, and the carrying capacity is also poor. Secondly, the linear bearing has greater vibration and noise during high-speed motion. An automatic selection of linear bearings is included. Linear bearings are widely used in sliding parts of precision, textile, food packaging, printing, and other industrial machinery.

Application of Ball Bearing

Most of these deep groove ball bearings have a shielded design, which means they do not require continuous lubrication or maintenance. However, some are open; adding some appropriate lubricants can prolong the service life and effectiveness of the bearing. Fortunately, ball bearings are also cheap and easy to replace if necessary.

Ball bearings are an essential part of heavy machinery. They are instrumental in the following areas: gearboxes, motors, pumps, construction equipment, construction machinery, wind turbines, agricultural machinery, mining, machinery and tools, office supplies, medical equipment, food processing machinery, aerospace.

These ball bearings are not limited to industrial use; they are also a standard part of the items in your home. Any appliance with a motor has at least one deep groove ball bearing, including washing machines, clothes dryers, vacuum cleaners, and dishwashers.
They are also found in computer fans, pool pumps, and even skateboards. Even the toy spinning top contains multiple ball bearings, allowing the toy to rotate in various directions.


What is a ball bearing? Ball bearings are widely used in auxiliary equipment with smaller loads and/or higher speeds. As an excellent bearing manufacturer and bearing supplier in China, TFL company can provide global customers with a series of radial ball bearings, thrust ball bearings, angular contact ball bearings, deep groove ball bearings, hub ball bearings, self-aligning ball bearings, inserts Bearings, bearing sizes support metric and inch. For detailed information on the classification of ball bearings, please get in touch with TFL engineers.

Ball bearings, also widely used in various applications, can bear a radial load and withstand axial loads. It is ideal for many of the requirements high speed, low noise, low vibration. When the ball bearing pure radial loads, the contact angle is zero. When the large ball of the radial bearing clearance, which has properties of a contact angle, coefficient of friction is usually relatively small, and also high bearing speed limit, particularly in the case of high-speed operation, the ball bearing even better.

For ultra-high-speed, ball bearings are very durable, without regular maintenance. The bearing structure is simple, high-speed limit, and ball bearings have the size and form of many changes. It has a wide range of applications in general machinery industries, such as precision instruments, low noise motors, and cars.

Ball-bearing is made up of which material?

Bearing materials – ceramics, chrome steels, stainless steels, and plastics.

Ball bearings can be used in various applications, from medical and packaging technology to electronics and office technology. Since these components have different types of materials, each material has its own set of characteristics and advantages; weighing the advantages and disadvantages of a specific type of ball bearing can become an important part of the design process. Ball bearings are usually made of steel, ceramic, or plastic. Although each ball bearing consists of four main parts: the inner ring, cage, and ball-each piece have unique characteristics.

Chrome steel bearings

The most common material used to produce load-bearing components in precision ball bearings, roller bearings, and tapered roller bearings is 52100 chrome steel.

Stainless steel bearings

Stainless steel is used to make bearing parts because it contains higher chromium (~18%) and nickel, making it more resistant to surface corrosion. Chromium reacts with oxygen to form a layer of chromium oxide on the surface, forming a passivation film.

Bearings made of plastic and non-metallic materials

Plastic materials are sometimes used for bearing cages, and the most common sealing materials are nitrile rubber or nitrile rubber.

Ceramic material bearing

Bearings made of ceramic materials belong to a special field of the bearing industry. The most common arrangement is a hybrid bearing, usually with stainless steel rings and ceramic balls.

A roller bearing is a cylindrical unit used to provide low-friction movement for a bushing or bearing seat. A ball bearing is a spherical unit that has the same goal as a roller bearing. The real difference is related to the contact surface between the bearing and the guide rail. The contact surface is just a point for ball bearings (assuming a perfect spherical bearing and no deformation).

Even considering the deformation, the amount of surface that the ball contacts with the track are limited. This creates an inherent strength limit for the ball. On the other hand, roller bearings have a complete contact line. This dramatically increases the rigidity, stability, and maximum load capacity of the system.

Ball bearing vs roller bearing

Ball Bearings
This extremely common bearing is light in weight and can withstand both thrust and radial load. It is a bearing that engineers love. When ball bearings move, their main job is to transfer the load from the outer raceway to the inner raceway. This allows smooth rotation. Ball bearings are commonly used in small wheels and hard disk drives, and other daily applications, but they are prone to deformation under excessive pressure.

Roller Bearings
Unlike ball bearings, roller bearings are designed with heavy loads in mind. These bearings are mainly based on cylinders, which means that the bearings can distribute loads over a large area and carry heavy loads. Also, different from ball bearings, roller bearings cannot bear thrust loads.

When designing a machine, it is important to select the bearing that is right for that machine. In this blog post, Koyo Bearings provides the criteria for choosing the correct bearing for your application. You can find the original post here.
