Carbon 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.

Tensile Strength............................................................53,000psi
Yield Strength................................................................44,000psi
Elongation in two inches..............................................26%
Reduction in area..........................................................50%
Modulus of elasticity.....................................................28 x 10
6 psi
Density...........................................................................0.284 lbs/cu. in.
