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 tapered roller bearing?

A tapered roller bearing is a bearing in which tapered rollers (truncated conical rollers) are inserted between the cup (outer ring) and cone (inner ring). The rollers are guided by the cone back face rib.

They have high radial and axial (thrust) load capacities at low to intermediate speeds. Taper roller bearings are available in single-row, two-row and four-row designs. With single-row bearings, the thrust load capacity is about 60% of the radial capacity. Double-row bearings have a greater radial load capacity and can handle thrust loads from both directions. The rollers can be configured so that the contact lines to the races converge or diverge towards the axis of rotation. Diverging double-row bearings increase the rigidity of the shaft mounting, but converging bearings do not. Other configurations for double-row bearings feature a single outer ring and two inner rings, or two outer rings and a single inner ring. Four-row tapered roller bearings consist of four rows of alternating converging and diverging rollers.
