Description
Solid Chrome Steel Balls
Well-Made
Modern furnaces with precisely controlled atmospheres and temperatures are used for heat treating to assure uniform hardness and proper microstructure for each steel ball.
High Hardness
Ball hardness is controlled within the 60-63 HRC range as measured on parallel flat surfaces.
Wide Applications
Bearing balls are used in automotive applications, for semi-precision bearings, and in commercial applications.
Other applications for steel bearing balls include bicycles, drawer slides, door locks.
Specifications:
Hardness: 60-63
Material: High Carbon Chromium Bearing Steel (GCr15)
Watch out for rust, store in a dry place.
Conditions such as high humidity or prolonged time outdoors can cause rusting.
