By combining innovative technology, technical expertise and advanced manufacturing equipment, we are able to develop and manufacture high performance and reliable bearings for the aerospace and aviation industry.

JTEKT offers a wide range of bearings for several applications in this field:

  • Aerospace 
  • Airframes
  • Engine & gearbox
  • Landing system
  • Mechanical aircraft accessories
  • Swash plates
  • Transmission

 Experience and capabilities

We manufacture bearings for angle sensors of parabolic antennas as well as EXSEV ceramic bearings, used in special environments like satellites and other space mechanisms. JTEKT has developed Koyo EXSEV bearings for use in applications where conventional bearings are not suitable due to the severity of the conditions. The EXSEV series are produced using special materials and lubricants which protect the bearing in extreme environments (high and/or low temperatures, clean areas, corrosive environment, vacuum spaces etc.)

JTEKT produces high performance track rollers for flap and slat actuation systems, for civil and various other applications. The design of these products is customized for each application. They are manufactured from high temperature stainless steels and enhanced with special features to cope with the severe working conditions.

We also possess a long experience of the design and manufacturing of ball and cylindrical roller bearings for jet engine main shafts of aircrafts and helicopters. Those bearings must maintain high performance and efficiency in severe operating conditions over extended periods of time while supporting the main shaft’s ultra-high-speed rotation.

In addition, we also supply compact and light weight bearings for jet engine gearboxes, which  are specially designed to guarantee stable performance under high-temperature and high-speed operating conditions.

In addition to these core applications, JTEKT supplies various types of bearings (tapered roller bearings and needle roller bearings) for landing wheels, steering systems and other aircraft accessories.

Products:

  • EXSEV bearings
  • Track rollers
  • Solid race needle bearings
  • Combined needle bearings
  • Cylindrical roller bearings
  • Thrust needle and cylindrical roller bearings

FAQ

What is a spherical roller bearing?

Spherical roller bearings feature a large load rating and self-aligning capability. This type of bearing is suitable for low- or medium speed applications which involve heavy or impact loading. Spherical roller bearings are self-aligning, double-row, combination radial and thrust bearings. They use a spherical or crowned roller as the rolling element. The outer ring contains a spherical race which allows for some misalignment of the shaft and housing. Spherical roller bearings are unequalled in their capacity for high loads and tolerance to shock loads, but have limited speed capabilities. They perform consistently, even under conditions of extreme speed, application-specific stress, and marginal lubrication. The cage of a spherical roller bearing provides high dimensional accuracy and functionality. According to some estimates, spherical roller bearings have twice the running life of conventional bearings.
