Introduction Ceramic materials such as silicon nitride applied to rolling element bearings have many advantages over traditional bearing steels.
The former are made of ceramic material, and the latter are comprised of inner and outer rings made of bearing steel while the balls are made of ceramic.

(3) Experimental materials, low-value apparatus and consumables management.
Experimental materials, low-value apparatus and consumables get in and out of depot is the most significant task of lab management.
Moreover, the rapid development of science and technology leads to higher requirements of equipment update frequency , which is much more difficult to increase funds for lab informatization construction.
