JTEKT Corporation TYO : 6473.T is a Japanese corporation created in January 2006 upon the merger of two companies: Koyo Seiko Co. and Toyoda Machine Works.
Toyoda Machine Works, Machine tool sales for North, Central and South America, aftermarket support services, machine re-manufacturing and engineering services supplied by Jtekt Toyoda Americas Corporation H.Q. Arlington Heights, Illinois and the Re-manufactured Products Division operate out of Wixom, Michigan, with support offices in Monterrey, Mexico and Itu, Brazil. JTEKT Corporation machine tools are manufactured in Japan by the JTEKT Corporation, and in Taiwan, by WELE Mechatronics, a "Toyoda Strategic Alliance Company", and exported globally.
JTEKT North America is a separate legal entity headed by COO Gary Bourque who reports to the CEO (Keita Mizuno). There are several locations of operations throughout the United States, Canada, and Mexico.
In 2009, JTEKT NA purchased the needle bearing business (automotive bearings) from Timken. [2] The needle roller bearing business was a part of the Torrington Company which Timken purchased in 2003. JTEKT gained five manufacturing locations along with a technical center and a business office in North America, as well as eight other locations worldwide.

AB SKF is a Swedish bearing and seal manufacturing company founded in Gothenburg, Sweden, in 1907. The company manufactures and supplies bearings, seals, lubrication and lubrication systems, maintenance products, mechatronics products, power transmission products, condition monitoring systems and related services globally.
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.
In mechanical engineering, a rolling-element bearing, also known as a rolling bearing, is a bearing which carries a load by placing rolling elements between two concentric, grooved rings called races. The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding.
The Timken Company is a global manufacturer of bearings and power transmission products. Timken operates from 42 countries.
The headset is the set of components on a bicycle that provides a rotatable interface between the bicycle fork and the head tube of a bicycle frame. The tube through which the steerer of the fork passes is called the head tube. A typical headset consists of two cups that are pressed into the top and bottom of the headtube. Inside the two cups are bearings which provide a low friction contact between the bearing cup and the steerer.
A thrust bearing is a particular type of rotary bearing. Like other bearings they permanently rotate between parts, but they are designed to support a predominantly axial load.
Hardy Spicer is a brand of automotive transmission or driveline equipment best known for its mechanical constant velocity universal joint originally manufactured in Britain by Hardy employing patents belonging to US-based Spicer Manufacturing. Hardy and Spicer soon became partners. Later Spicer became Dana Holding Corporation.
The TREMEC T-5 is a 5-speed manual transmission for longitudinal engine automobiles. It includes one overdrive gear, a lightweight aluminum housing, and adaptability for four wheel drive use. It is currently manufactured by TREMEC.
Koyo Seiko was established as a private company by Zenichiro Ikeda in 1921. They initially sold imported bearings but by 1935 had begun production of Koyo branded bearings under the name Koyo Seiko Co., Ltd.
Schaeffler Technologies AG & Co. KG, also known as Schaeffler Group, is a German manufacturer of rolling element bearings for automotive, aerospace and industrial uses. It was founded in 1946 by brothers Dr. Wilhelm and Dr.-Ing. E. h. Georg Schaeffler.
The Torrington Company was a firm that developed in Torrington, Connecticut, originally called the Excelsior Needle Company. It was formed in 1866 around the new idea of using a "cold swaging" technique to create better sewing machine needles, but also produced a lot of other things as it got bigger, since the 1950/ focusing mainly on producing bearings, especially needle bearings. In 1980, it was the largest employer in Torrington.
NRB is India's largest needle and cylindrical roller bearings manufacturer, headquartered in Mumbai.
NTN Corporation is one of the most prominent manufacturers of bearings in Japan, second domestically only to NSK Ltd. The company is one of the largest exporters worldwide of friction-reducing products such as constant-velocity joints.
A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment. Typically these bearings support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring. The misalignment is possible due to the spherical internal shape of the outer ring and spherical rollers. Despite what their name may imply, spherical roller bearings are not truly spherical in shape. The rolling elements of spherical roller bearings are mainly cylindrical in shape, but have a profile that makes them appear like cylinders that have been slightly over-inflated.
GGB manufactures self-lubricating, prelubricated plain bearings and tribological polymer coating for various industries and applications. It has production facilities in the U.S., Germany, France, Slovakia, Brazil and China.
NBC Bearings is the brand of National Engineering Industries Limited (NEI), a part of the US$ 2.8 billion C K Birla Group, which manufactures a wide range of bearings for the automotive, industrial, aerospace and railways sector. The company had a gross turnover of Rs 1352 crores in 2013-14. NEI is capable of developing bearings from 6mm bore to 2000mm outer diameter, in over 2300 sizes. The company was founded by Mr B. M. Birla in 1946 in Jaipur, Rajasthan, India. Its products are exported to more than 30 countries across five continents. Product range includes ball bearings, taper roller bearings, cylindrical bearings, spherical roller bearings, needle roller bearings, railway axle boxes and other special products. NEI also serves the Indian aftermarket through a countrywide network of 550 authorised stockists and thousand of retailers.
