We rely on the production of food, fiber and other agricultural products more than we realize.

We rely on the production of food, fiber and other agricultural products more than we realize.

The machines and tools which are being used to grow and collect the crops must be in the best possible condition in order to increase and optimize the productivity and fulfill the needs of the world’s growing population.

Agricultural applications are asking for bearing designs which are at the same time reliable in operation as well as dirt- and humidity-proof. Furthermore, agriculture equipment such as tractors, mowers, silage cutters, cultivators, front loaders, trailers, harvesters, baler pressers, hoes and ploughs need to be provided with bearings capable of faultless operation under significant temperature changes and varying load, speed and surrounding conditions.

The importance of bearings in agriculture machines is essential. With our knowledge and experience in this field JTEKT has developed Koyo bearings which can withstand ‘the elements’ and provide reliable operation at any time.

Experience and capabilities

JTEKT products are present in all agriculture and construction vehicles and equipment, whether in their drivetrain, in their power units or in their accessories. Typical applications are planetary, helical and spur gear reducers, steering systems, pumps and driveshaft. The unbeatable quality of our products and their specific designs allow our customers to guarantee superior performance to the end users under the extreme operating conditions (temperature, pollution, etc.) of those applications.

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.
