These small, high-grade bearings have applications in aerospace, automotive, military, electronics, power, industrial machinery, and medical devices.
John H. Glenn Research Center, Cleveland, Ohio
Innovators at NASA's Glenn Research Center have developed a new method for making small-diameter, high-grade ball bearings that are less than 0.25" in diameter thanks to the development of a new alloy made of 57.6% Nickel (Ni), 39.2% Titanium (Ti), and 3.2% Hafnium (Hf). The use of non-corrosive NiTi alloy instead of steel is an inexpensive way to increase the load capability...
