Steel

It is difficult to imagine a world without steel and iron, so used have we grown to its everyday presence in our lives.

It is difficult to imagine a world without steel and iron, so used have we grown to its everyday presence in our lives.

The global steel consumption has risen significantly in the course of the 20th century, in highly developed, emerging and developing economies likewise. The steel consumption of a country has been a barometer for measuring the dynamics of economic progress. JTEKT is making its contribution to this immense industry by manufacturing a large range of bearings which are being used in the steel manufacturing plants.

Experience and capabilities

Bearings for steel manufacturing plants are bound to operate in very harsh environments including extreme temperatures, contamination and operation under very diverse speeds. Thanks to our ample technological knowledge gained through intensive R&D we are capable of manufacturing a complete line of products for a variety of steel making applications such as roll necks, pinion stand, screw down and drive shafts. Koyo advanced bearings are highly recommended for those environments. Their excellent performance and high reliability considerably prolong the service life and reduce maintenance frequency.

FAQ

What is a bearing?

A bearing is a moving device that supports rotational movement between a stationary part and a rotating part. There are several types of bearings like slide, magnetic and rolling bearings. Koyo bearings are “Rolling Bearings” Rolling bearings have a long service life, high interchangeability and is power saving. The rolling elements of the bearings are assembled between inner and outer rings with or without cage. With this structure, a smooth rolling motion can be realized during operation. The great advantages of rolling bearings are:

  • Low starting friction
  • Ability to support both radial and thrust load and high speed rotation
  • Easy to handle and maintained
  • Interchangeable and easy acquirement (global normalization & standardization)
  • Can operate in extreme environments (high and low temperatures)
  • Simple methods of grease lubrication

Bearings are critical elements in all types of machinery and products. You can find them for example in automobiles, airplanes, home appliances but also in equipment for malting steel and semiconductors.
