Deep Groove Ball Bearings - Working Principle, Features, and Application

The most common type of rolling bearing is deep groove ball bearings. An outer ring, an inner ring, a set of steel balls, and a set of cages comprise the basic deep groove ball bearing. Deep groove ball bearings are available in single row and double row designs. The deep groove ball structure is further classified into two types: sealed and open. The bearing is classified as open if it lacks a sealing mechanism, and the sealed deep groove ball is divided into a dustproof seal and an oil-proof seal. This blog is a quick guide on deep groove ball bearings:



Working principle

Deep groove ball bearings are mostly subjected to radial loads, but they can also handle axial loads. When only radial loads are applied, the contact angle is zero. When a deep groove ball bearing has a large radial clearance, it acts as an angular contact bearing and can withstand high axial loads. Deep groove ball bearings feature a high-speed limit and a low coefficient of friction.


Features

  • Deep groove ball bearing are the most common and regularly used rolling bearings.
  • It is extremely durable and requires very little maintenance, making it suitable for high and even very high speeds.
  • The bearing features a low friction coefficient, a high limit rotation speed, a simple structure, a low production cost, and is simple to manufacture with high precision.
  • It has a wide range of dimensions and shapes, and it is used in precision instruments, low-noise motors, automobiles, motorcycles, and general machinery. It is the most common type of bearing used in the machine industry.
  • It is mostly subjected to radial loads, but it can withstand axial loads to a certain point.

Application

Deep groove ball bearings can be used in clutches, instruments, motors, home appliances, internal combustion engines, transport vehicles, farming equipment, construction machinery, roller skates, yo-yos, and other purposes.

A Refresher on the Ball and Roller Bearings

Image
Almost all machines have many distinguished components and use a variety of bearings that allow for smooth and hassle-free functioning. Even though there is a wide variety of a bearing available in the market, the most widely used ones are roller bearings and ball bearings. Both of these types are meant to support dynamic and exemplary operations. The key difference between them is in their design. Ball bearing is composed of small spheres, which results in a small point of contact with the load. Conversely, the cylindrical-shaped Roller bearings’ area of contact with a load is in a line.  Hence, it can support the load more effectively and spread along with it. Use of rolling element There is a rolling element, cage, and bearing rigs that consist of a bearing in both  ball and roller bearings . If the rolling element in the bearing is a spherical ball then it is just termed a ball bearing.  Roller bearings can withstand heavy loads  The roller bearings use rollers rather than

A Refresher On Buying Bearings As Per Load Capacity

Image
The majority of bearings with a rolling element fall into two broad groups, ball bearings and roller bearings. There additionally are several sub-categories of bearings within these groups that have their own optimized designs or unique features that help in enhancing performance.  Before you search for ‘Buy bearings near me’ on the web, you need to determine exactly what type of bearing you would need for your application. Find the bearing load and load capacity Bearing loads are typically defined as the reaction force a component tends to place on a bearing when it is in use. When trying to select the right bearing for your application, you need to first find the load capacity of the bearing. Its load capacity implies the amount of load the bearing shall be able to handle.  Bearing loads can either be radial, axial or a combination of both. In the case of axial bearing load, the force is parallel to the axis of the shaft. On the other hand, a radial bearing load refers to when force

Bearing Housing: Types and Features

Image
Bearings are an important part of modern machinery and appliances as they support the machinery parts, reduce friction, and ensure the seamless movement of adjoining parts. These engineered components are housed in the bearing housing. Bearing housings are modular assemblies engineered to protect the bearings from contaminants and assist in easy bearing installation. They have an important role in simplifying the maintenance process, improving the service life, and optimising the bearing performance. Numerous bearing designs and sizes are available in the market that meet different requirements. The bearing housing price depends on the type of bearing required for your machinery. Types & Features of Different Bearing Housings Split Plummer Block Housing The housing body in a split plummer block housing is divided into upper and lower components that go well together for a typical shaft-bearing combination. This is very crucial to allow easy mounting and maintenance of the bearings
