These bearings have the functions of corrosion-resistance,Website:://.zys-bearing.com, heat-resistance, radiation-resistance, abrasive resistance. Without magnetism themselves, the bearings can work in high-intensity magnetic field. They are mainly used in the instruments, nuclear reactors and highly sensitive guidance systems. The non-magnetic materials of the bearings include: 0Cr40Ni55Al3, Cr23Ni28Mo5Ti3AlV (G52# Alloy), GH05 Alloy and so on.
