Bearings refer to “machine parts that assist with rotation.” They support the shafts inside the machinery that rotates with it.
Bearings exist in a variety of machines, such as automobiles, airplanes, and electric generators. Our daily lives are impacted by them, too, since they appear in household appliances like refrigerators, vacuum cleaners, and air conditioners.
These machines depend on bearings to support all their rotating shafts, which allows them to move smoother.
Thus, all sorts of machines cannot operate without shafts because they always need bearings, hence their reputation as “the bread and butter of the machine industry.” Bearings may seem like simple mechanical parts, but they are essential to human life.

Functions of Bearing
Make rotation smooth and friction-free:
The shaft and the part that supports it rotates are bound to have friction between them due to the rotation. The two of these components are linked together with bearings. By reducing friction, the bearings allow rotation to be smoother. As a result, energy consumption decreases. It performs this function exclusively.
Defends the rotating shaft and maintains its correct position:
The shaft that rotates and the support part that supports it requires a lot of force. It protects the rotating shaft from damage caused by this force by stabilizing its position and preventing damage from being done to it by this force.

Types and Uses of Bearing
A Ball Bearing:
A ball bearing consists of spherical elements thrust between circular races captured between a spherical inner and outer ring. They minimize friction between rotating shafts and stationary machine members by providing a means of supporting the shafts.
Use: The main use of ball bearings is to support low friction rotation of shafts in machinery. The most important configuration is shielded or sealed. They are standardized to permit interchangeability. Alternatively, they can be called rolling element bearings or antifriction bearings.
A Roller Bearing:
A roller bearing is a mechanical assembly that consists of cylindrical or tapered rolling elements typically enclosed between internal and external raceways. As a result, they provide a way to support rotating shafts and minimize friction between rotating shafts and stationary machine members.
Use: The bearings typically appear in machinery with rotating shafts that support heavier loads than ball bearings. The thrust load capacity of tapered roller bearings is higher when compared to radial load capacity. Rolls are available as cylindrical, spherical, and a variety of other types. Despite their lesser standardization, roller bearings follow the same pattern as ball bearings.
The Mounted Bearing:
A mounted bearing is a mechanical assembly comprising a bearing held within a bolted or threaded mounting component, such as a pillow block, flanged unit, etc. They eliminate friction between rotating shafts and stationary machine parts by supporting rotating shafts.
Use: Mounted bearings typically appear in machinery with exposed rotating shafts. Bearings mounted on a shaft are designed for bolt-on installation and ease of replacement. On conveyor ends and as flanges with intermediate points, they are used to take uploads. Additionally, bearings can incorporate rolling elements or journal bearings.
The Linear Bearings:
The linear bearing consists of ball or roller elements captured in housings that provide linear movement along shafts. The main application for linear bearings is machinery that must linearly move along shafts.
A Slide Bearings:
A slide bearing is a mechanical assembly designed to provide axial movement between structural elements.
Use: A slide bearing serves as structural support for bridges and large buildings. These components accommodate thermal movement, and beam rotation occurs through these components. Isolation against shock, vibration, and noise is also available through these components. Other slide bearings include those used on truss base plates, heat exchangers, and process equipment.
A Jewel Bearing
A jewel bearing is a mechanical device used in applications such as watches, meters, gyroscopes, and others where the loads are small and the shafts involved are small. They are made of almost any synthetic material, although ruby and sapphire are particularly popular.
A Frictionless Bearings
As mechanical or electromechanical alternatives to conventional bearings, frictionless bearings offer shaft support controllable through the air, magnetic fields, etc., for critical, high precision applications.
Bearing Companies In India
- A shaft (Shafting) is generally a metallic component that rotates axially to transmit motion.
- Hydraulic, pneumatic, and radial shaft seals are mechanical devices used to seal the components of reciprocating and rotating shafts where oil or grease is used for lubrication or as an actuating force.
- Lubricating greases are semi-solid mixtures of additives such as oil and mineral oil containing thickeners that make them more viscous than oils, preventing wear on contact surfaces.
- Lubricating Oil is a slippery, viscous liquid made of various mineral, plant, animal, and synthetic substances. Normally, it is a mixture of liquid, gaseous, and solid hydrocarbons used as lubricants. The substance can also be produced synthetically or eaten.
- A plain bearing (a bushing) is a mechanical element used for reducing friction between rotating shafts and stationary support members. The bushing usually supports the rotating shaft on the hardened journal of the shaft by means of thin metal or plastic and a thin oil film.
- Bearing Isolators safeguard bearings from fluids and other contaminants by sealing them.
The Market Overview of Indian Bearing
Due to many players, including major players in the industry, the Indian bearings market is highly fragmented. Increasing demand for bearings is directly related to the expansion of the automotive and industrial markets. Further, the growing demand for high-performance, lightweight smart bearings in automobiles, along with the demand for anti-friction bearings in pumps, gearboxes, heavy earthmoving equipment, and industries, is helping to propel the demand for bearings in India. However, the domestic bearings market is facing competition from the counterfeit bearings market, primarily imports from China that would, in turn, hinder the market growth.
The India bearing market is expected to grow substantially during the forecast period owing to its demand from the automotive sector. In 2019, the automotive bearing market alone was valued at US$ 953.4 million.
There are many applications for bearings in the railway & aerospace sectors, which are expected to grow rapidly over the next few years due to the increasing demand for small aircraft and the growing construction of railways. In addition to automotive, construction, agriculture, and oilfield equipment, the bearings market also caters to other major end-user applications.
Key Competitors of the India Bearing Market are:
- Schaeffler Group
- NTN Corporation
- NSK Global
The market has also benefited from government policies such as Make in India, Automotive Mission Plan, and National Automotive Testing and R & R&D Infrastructure Project (NATRIP).
With the increasing production volume of vehicles in the country and the implementation of the Bharat Stage-VI (BS-VI) norms, it is no surprise that the demand for automotive bearings has soared to unprecedented levels. The automotive bearing market will likely grow with a multiplier effect, mainly due to the BS-VI requirements from 2020. For example, the market is likely to grow as the demand for new engines and automobiles increases. Nevertheless, raw material prices are on the rise, consumers’ consumption levels are down, and counterfeit products are rising.
