NTN Bearings Corporation manufactures and supplies a comprehensive range of bearings, constant velocity joints, and other industrial and automotive precision parts for a wide variety of applications, and across an array of various industries. 75 plants across the globe and more than 100 years of premium manufacturing renders NTN the third largest bearing manufacturer in the world.

Why are NTN high-temperature bearings necessary?

The operating temperatures of machines have been steadily polarizing between high-temperature and low-temperature as time has gone on. Seeing as the composition of both metal and plastic is changed by temperature, NTN high-temperature bearings have become a necessity. 

In the case of bearing steels, if the annealing temperature is exceeded, the structure softens, the life span shortens, and the size changes. With plastic, adding heat causes melting and the plastic becomes unable to withstand even a slight external force. High temperatures also cause such phenomena as fusion and carbonization to occur. All these reasons and more called for the creation of NTN high-temperature bearings.

What do NTN high-temperature bearings do?

To minimize size changes and softening at high temperatures, NTN created a composition and that could withstand special heat processing and surface processing. By applying their treatment to the special stainless steel they create their NTN high-temperature bearing with, these practical bearings can rotate at the high temperature of 400 degrees Centigrade.

How does NTN create high-temperature bearings?

NTN does this in a variety of ways including:

  1. By Increasing Molecular Weight - By making the molecules that compose the material form more bonds than usual heat resistance and other mechanical properties are improved.
  2. Using Filler-Based Method - If the material is filled with carbon fiber, glass fiber, nanosized fillers, and other fillers the mechanical strength at high temperatures is increased.
  3. And Other Methods - Methods that introduce carbon-fluorine bonds, silicon-oxygen bonds and ring structures develop material whose heat resistance exceeds 400 degrees Centigrade.
