AISI 304 stainless steel, widely used as corrosion- and heat-resistant steel and also as nonmagnetic steel, is most suitable in corrosive environments where AISI 440C stainless steel can not be used.
- Higher corrosion resistance than AISI 440C stainless steel bearings
[Difference in properties by the material used]
|AISI 304||AISI 440C||SAE 52100|
* AISI 304 stainless steel may be magnetized depending on manufacturing process.
|Inner and Outer Rings||AISI 304|
Special bearings are also available in quick delivery with the specifications below:
*1 Ceramic balls (Silicon nitride Si3N4)
*2 Fluorine rubber seal
*3 Heat- and chemical-resistant fluorine grease and other special greases
●Food processing machinery, cleaning equipment, LCD and semiconductor manufacturing equipment, metal plating equipment, other equipment used in environments where the bearings come into contact with acid or alkaline chemicals.
AISI 304 stainless steel is not appropriate for use under heavy load or at medium to high rotation where AISI 440C stainless steel is usable, because it can not be hardened by heat treatment.
