What Is Bearing?

Bearings are machine elements that allow components to move with respect to each other. There are two types of bearings: contact and non-contact. Contact-type bearings have mechanical contact with equipment, which includes sliding, rolling, or flexural bearings.

Non-contact bearings include liquid, air, mixed-phase, and magnetic bearings. The lack of mechanical contact eliminates static friction.

A bearing is a machine element that constrains relative motion to only the desired motion and reduces friction between moving parts.

The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts.

Most bearings facilitate the desired motion by minimizing friction. Bearings are classified broadly according to the type of operation, the motions allowed, or the directions of the loads (forces) applied to the parts.

Selection Of Bearing Type

Selecting a proper bearing for our application is a very important thing. Here is a quick guide for selecting the right bearing.

• For low and medium loads select ball bearings, and for heavy loads select roller bearings

• In case of misalignment between shafts self-aligning ball bearings or roller bearings are used

• For medium thrust loads, radial thrust bearings are selected and for heavy thrust loads cylindrical thrust bearings are used

• For situations where we have both axial and radial components of load, we use deep groove ball bearings, angular contact bearings, and spherical roller bearing

• For high-speed applications deep groove ball bearings, angular contact bearings and cylindrical roller bearings are recommended

• When the rigidity of the system is our main requirement like in machine tools, we use double-row cylindrical roller bearing or taper roller bearing

• When noise reduction is our main criteria, we use a deep groove ball bearing

Applications Of Bearing

• Aviation Cargo Systems.

• Aerospace Wing Actuators.

• Anemometer.

• ATMs & Card Readers.

• Bicycles.

• Commercial Blenders.

• Dental Hand Tools.

• Electrical Motors.

Advantages Of Bearings

• The friction resistance and the power consumption are small, the mechanical efficiency is high, and is easy to start.

• Size standardization, interchangeability, easy to install and disassemble, easy to repair.

• The structure is compact, the weight is light, and the axial size is narrower.

• High precision, large load, and long service life.

• Some bearings have the performance of automatic heart adjustment.

• It is suitable for mass production, the quality is stable and reliable, and the production efficiency is high.

• The friction torque of the transmission is much lower than that of the fluid dynamic pressure bearing, so the friction temperature rise, and the power consumption are low.

• The axial size is less than the traditional fluid dynamic bearing.

• The combined load of radial and thrust can be borne simultaneously.

• Within a large load-velocity range, the unique bearing design can achieve excellent performance.

Disadvantages Of Rolling Bearings

• The noise is great.

• The structure of the bearing seat is complex.

• The cost is high.

• Even if the bearings are lubricated well, installed correctly, and well-sealed, and the operation is normal, they will eventually fail because of the fatigue of the rolling contact surface. If you want to learn more about bearings, please don’t hesitate to contact us.
