For 80 years, Hartford has manufactured precision steel balls in stainless
steel, chrome steel, and carbon steel, also tungsten carbide and brass.
We produce a broad range of geometric tolerances and sizes, including
miniature balls.

   Hartford precision steel balls are manufactured for the widest range
of service environments; a range of surface finishes, coatings, platings, and
heat treating processes are applied to optimize performance, maximize
service life, and to minimize maintenance.

   Hartford precision steel balls are vital to products as diverse as cars
and cosmetics, pumps and power tools, valves and vacuums. They are a leading
choice for applications that involve extreme wear and temperature conditions.

And if you manufacture valves, Hartford has extensive capabilities and
expertise for the design and manufacturing of balls for valves.

Our extensive manufacturing capabilities and logistics on both sides of the
world can accommodate immediate needs, future requirements – and rush
projects virtually anywhere in the world. (See PDF)
