High Quality 3.5mm Diameter loose grade 100 AISI440 stainless steel ball bearings

Stainless steel AISI 440-C offers the advantage of higher through hardness than other stainless steel material, as well as a considerable resistance to corrosion against water, steam, oil, gasoline and alcohol.

The high hardness, grade surface finish, and extremely accurate tolerances ensure that this type of steel is suitable material for stainless steel precision ball bearings, oil refinery valves, ball-point pens and other rigid environmental applications.
