Chrome 52100 VAC-ARC steel balls are widely used in high-precision and aerospace applications. Chrome 52100 VAC-ARC is a deep hardening alloy steel used for aircraft bearings and other high stressed parts where good rolling contact fatigue strength is required at operating temperatures below 400°F.  This grade is produced by the vacuum-arc remelting process and offers greatly improved cleanliness and internal soundness over conventionally air melted bearing quality SAE 52100 steel.

Small size balls are made from wire stock while larger size balls are hot forged from bar stock. Modern furnaces with precisely controlled atmospheres and temperatures are used for heat treating to assure uniform hardness and proper microstructure for each chrome steel ball. Throughout the manufacturing process, statistical process control assures tolerance accuracy, fine surface finish and consistent high quality.
