Special Specialty Items At Salem

Tooling and checking balls
          If you have special inspection and measurement needs, Salem Specialty Ball Company can also provide you with premium TOOLING and CHECKING balls. A Two piece construction is used to retain the high precision and finish of the balls. All of our tooling balls are made from SS440C material which is a martenistic-type stainless steel that is used extensively in bearing applications that require hardness, dimensional stability, corrosion-resistance and toughness. This 440C material is measured on the Rockwell C scale from 55-58 for hardness. A proprietary welding technique is used in the assembly of the Ball to the Shank, some have a shoulder and some are without. Some tooling balls can be found in stock and some are special made to order. Standard sizes are 1/8" to 1" in increments of 1/8" size. Most shank lengths come in a standard size in comparison to the size of the ball that you are ordering. You must supply a drawing of any special dimensions that you are inquiring about when requesting the size of the ball and size of the shank that would not be considered an industry standard. As always, we pride ourselves on quality of product and exceptional value. Call 1-877-844-4885 to inquire about price and delivery for your Special Specialty items at Salem Ball Company.
