S608ZZ Bearing 8*22*7 mm ( 10PCS ) ABEC-1 440C Roller Stainless Steel S608Z S608 Z ZZ Ball Bearings

WHY 440C STAINLESS steel?

Good corrosion resistance to water and many weak chemicals

Corrosion resistance can be improved by passivation

Good for temperatures up to 300°C

Slightly softer than chrome steel so lower load ratings

Will corrode in salt water or salt spray and poor resistance to acids/alkalis

More expensive than chrome steel
