Koyo Bearings

Koyo Seiko and Toyoda Machine Works formed their businesses at the dawn of Japanese industry. In 2006, these two joined and became JTEKT,"a new global company combining modern innovation with a rich heritage". 
There are many different types of rolling element bearings. The key in determining a bearing type is the style of the rolling element itself. Although ball bearings are available in different configurations and designs, they are still identified as ball bearings because of the rolling element. Bearings using rollers element can be in various shapes. This section you will find ball type cylindrical roller, needle roller, tapered roller, spherical roller, convex roller.  
Roller bearings will have a line contact area between rollers and rings and will provide heavier load capacities compared to a point contact ball. However , the point contact ball will generate less rolling friction than a roller element bearing, making it better suited for higher operating speeds.
