Carbon Steel Balls

Carbon Steel Balls

Carbon steel balls provide substantial savings for applications where conditions do not require a through-hardened ball. They add superior performance and dependability to products which utilize inexpensive anti-friction bearings. Typical applications include: casters, conveyors, roller skates, bicycles, overhead trolleys, drawer slides, garage doors, door locks and many others.

Chemical Analysis:
Carbon.....................................................................0.10% to 0.20%
Manganese..............................................................0.60% to 0.90%
Silicon.......................................................................0.10% to 0.20%
Sulphur.....................................................................0.50% maximum
Phosphorus.............................................................0.040% maximum

Mechanical Properties:
Hardness for carbon steel balls, as measured on the balls surface is Rockwell “C” 60 (minimum) and subject to correction factors. See chart for minimum case depth.  Case depth reported is the effective case measured to the HRC 50 position (ref. ABMA Std. 10-38).  Minimum thickness considerations apply to case depth.

Reduction in area..........................................................50%
Modulus of elasticity.....................................................28 x 10
6 psi
Density...........................................................................0.284 lbs/cu. in.
