Precision Balls

Chrome Steel Balls (Bearing Steel)

Chrome Steel Balls

General Information:
These Balls are manufactured from the highest quality carbon chrome steel (SAE 52100-equiv. to EN31) which is specially produced to a very rigid specification. They are hardened right through by a carefully controlled heat-treatment process, lapped and highly polished. Although mainly used in bearings, these balls find countless applications where precision, hardness and low cost are prime considerations.
