Industry Standard Grade 100 420 Stainless Ball Bearings: 420 Graded High Quality Stainless Steel Ball bearings made from AISI 420 Stainless Steel with a hardness of 52 -55 HRC Rockwell Scale, the hardness is all the way through the ball. These stainless 420 steel balls are the same that are used to manufacture bearing assemblies and have a high duty and life cycle.
Made from the commonly used martensitic stainless steel which offers good resistance to corrosives such as fresh water, steam, petrol, alcohol, blood, sweat, oils and foodstuffs.
Manufactured in compliance to the following international standards: AISI 420 / BS970 420S37 420S45 / DIN 1.4021, 1.4025, 1.4034 / AFNOR Z30C13, Z40C14 / JIS SUS 4200JI, 420J2

Steel Ball Measuring Diameter
  • These stainless steel balls are made from AISI 420 Stainless Steel.
  • Uniformly hardened and tempered all the way through the ball to achieve maximum strength and quality
  • Ball hardness is controlled within the 52 - 55 HRC range as measured on parallel flat surfaces.
  • Ball grades are defined numerically 100 - 1000 (50 being highest quality available in 420 stainless, 1000 is the lowest)
  • 420 Stainless balls are attracted to magnets
