Roller bearings are self-aligning bearings with roller held by retainer between inner race and outer race. They can take the form of single or double row bearings.

Aerospace applications demand bearings that deliver exceptional durability, providing a consistently superior performance despite changes in temperature and air pressure.

In addition to meeting MIL specifications (U.S. military standards for design and performance commonly applied to commercial aircraft), MinebeaMitsumi has obtained certification from major commercial aircraft manufacturers, making the company one of the only 2 bearing suppliers to have achieved this certification worldwide.
