The global bearing trade valuation is at $107.46 billion in 2019 and should reach $143.53 billion by 2027. The bearing is a machine element part that supports the relative motion. It helps to minimize friction causing the moving parts to slow down and erode. Various industries require bearing, and these are:
- · Wind Turbines
- · Automobile
- · Construction Machinery
- · Mining Trade
- · Machine Tools
- · Agricultural Equipment
They are used in the automobile to smooth the running of lightweight passenger cars, individual automobiles, electric automobiles (EVs), and other types of vehicles like heavy automobiles like truck trailers.
Prominent bearing producers are NSK Bearing and FYH Bearing. Some widely used bearings are ball bearing, spherical rod ends, tapered bearings, agricultural bearing, etc.
The universal bearing industry is gaining more importance to increasing the use of bearings in various end-use trades like electric cars and rolling mills. Recent steady technological improvements have developed the overall efficiency of the bearing items in the automobile sector. Product service life also increased by multitude proportion.
This article provides comprehensive aspects of various bearing companies and significant bearing types.
FYH Bearing Manufacturer
FYH is a Japanese bearing manufacturer with its head office in Osaka. The company came into operation on November 4, 1950. They currently have a business capital of 45 million yen. They have 121 highly skilled professionals.
1. History
FYH bearing started commercial production of pillow block bearings, a kind of rolling bearing unit, and spherical rod ends. Since then, they have continued their operation as the top manufacturer of pillow block bearings. They specialize in producing the best quality pillow block rolling bearings that support the world-bearing industry’s development.
2. Operations
FYH bearing has a cutting edge technology production facility. From production to quality control, every step is a fully automated process. The company implemented stricter bearing finish tolerances standards, which are higher than Japanese commercial products. Bearings coming out of FYH bearing factories are fully ready to cope with the roughest using conditions and operate seamlessly at very high speeds.
The organization produces about 300 types of bearing housings and 700 types of bearings. More than several thousand types of pillow blocks are manufactured from a wide variety of bearing combinations. It is a crucial contribution to the bearing industry. Pillow blocks made by FYH can withstand contaminations like soil, dust, chemicals, high temperature and offers a longer service life.
Pillow blocks of FYH vary depending on the raw material. It is mainly to produce several types of rolling bearing units as per requirement by clients. Some of the widely sold pillow block assemblies are

3. Manufacturing Technology
The technical design of spherical rod ends bearing units is pioneering as FYH produces bearings and bearing housings in-house, starting to finish products. “J-fitting” is an in-house technology of this company for pillow block assemblies.
The technique’s essence is reducing tolerance in the middle of the roundness and sphericity of inner diameter housing. This unique processing of bearing design enables the bearing to portray premium qualities such as:
- · Accommodate heavy loads from various directions
- · Protect the bearing from wear and tear during daily usage
- · Blocks vibration, which could harm the unit
- · Increase bearing unit service ceiling
The “J-fitting” technology is fully compatible with any housing and bearing types.
4. Product Series and Features
There are several bearing product series of this firm. They are as follows:

- · ZK series units combine conventional UK tapered hole bearing with FYH bearing indigenous Z lock sleeve, thus replacing the adapter.
- · This series of bearings are easy to install with a single hex wrench. Anyone can install the bearing unit by hand.
- · These units do not require a torque wrench. Also, there is no over-tightening effect on bearing clearance.
- B. Stainless Series
- · The latest stainless FYH bearing allows no water droplets to stick to the bearing or its housing. The surface is treated with a laser to convert washing into an effortless job.
- · Bacterial contamination incidences also decrease.
- · The product has increased corrosion resistance. All units are initially filled with H1 grade food grease. Hence, such bearings can be used in food industries without any second thoughts.
- · These units can withstand a temperature range of 0°C to 100°C.
- C. Self-Aligning Roller Bearing Series
- · These are FYH bearing in-house developed and manufactured units, both the bearing and housing. The product gets the extra tough certification due to a special technology production line.
- · The bearing has a triple lip seal with the center-able angle of ± 2 °. It allows auto-alignment of bearing with any change in shaft angle.
- · Installation is effortless, and maintenance is convenient when comparing with Plummer block bearings.
- · The roller grease is 100% synthetic and can withstand a temperature range from -40° to 170 ° C.
NSK Bearing Manufacturer
NSK bearing is another global leader in bearing and related products manufacturing. The company was established in Japan. It was founded on November 8, 1916. Currently operating capital is approximately 67.2 billion Japanese Yen as of March 31, 2020. It employs a robust number of people, 30,747 skilled professionals. The firm netted 831.0 billion Japanese Yen (Year ended March 31, 2020).
1. History
The company produced the first ball bearings in Japan in 1916 and since then pioneered the country’s industry. Today NSK bearing offers a wide range of bearings, bearing-related spares, spherical rod ends, specialized technology, etc., worldwide. It is the largest bearing company in Japan and one of the biggest bearing suppliers in the world.
NSK bearing focus to contribute to the goodness of society. It also aims to ensure the safety and protection of the global environment through innovative technology and sustainability. Their technology aims to integrate motion and control.

- B. Angular Contact Ball Bearings
- These are constructed of a contact angle that enables them to accommodate substantial axial loads in a single direction also radial loads. They usually are used as pairs, 2 pair sets, triplex sets, or multiplex sets as an axial load is produced when the machine applies radial load.
- C. Self-Aligning Ball Bearings
- Such ball bearings are needed when the arrangement of the tube/ shaft and casing is challenging, and the shaft may bend. High quality and ultra-clean steel are used in manufacturing, increasing service life up to 80%.
Spherical Rod Ends a Specialist Tool
Spherical rod ends contain an eye-shaped crown with an integral stem that forms housing for a spherical plain bearing. As per the rule, rod ends are existing with left- or right-hand internal or external threads.
Several bearing manufacturers sell rod ends with a threaded rod with a right-hand strand as the industry standard. With the omission of rod ends with the description suffix such as VZ019, many rod ends are also offered with a left-hand rod. The label prefix L brands them.
Conclusion
Bearings ultimately enhance machine performance while reducing energy requirement, wear, and tear. Mobearing is a premium company that stocks and distributes bearings made by all brands, such as FYH bearing and NSK bearing. Furthermore, the entity is also capable of supplying bearings parts as spherical rod ends.
