  • 不锈钢滚珠( AISI 型 302/316)具有非淬火硬度、均匀分布(在平行平晶上测定)的特点,一般为洛氏硬度“C”25 至 39†。 可选淬火洛氏硬度“B”75 至 90†。



Pioneer Steel Ball was founded in 1946 in Unionville, Connecticut by five men who had extensive experience in the steel ball industry. The idea to form the company took root several years earlier, but since the founders did not want to jeopardize the war effort in any way, they waited until the war had ended. In the forties and fifties, Pioneer, produced carbon steel balls for bearings and the automotive industry. In addition, the company manufactured a variety of steel sizes and shapes for the burnishing industry. Pioneer’s growth outpaced their capital and in the early ‘50s they sold the company to Pittsburg Steel with the option to repurchase it at a later date. Unfortunately, they bought back the company a few months before the devastating hurricane and flood of 1955. Located on the banks of the Farmington River, the company took a direct hit and was destroyed. However, it was rebuilt by two of the former five partners who later expanded the product lines to include High Carbon Chrome SAE 52100 as well as a full line of stainless steel types: 440C, 302, 316. The partners also added lapping machines to produce tighter tolerances and improved surface finish. One of their greatest accomplishments was to develop the 36” flashing machine, the largest at that time. This accomplishment was the result of their combined expertise which had been acquired over sixty years in the steel ball business. Pioneer’s innovative leadership continued with the development of extremely strong hollow stainless steel 440 balls for the air cargo industry. They also developed a special stainless steel type 431 gold- plated with extremely high tolerance for the automobile air bag deployment mechanism.

A second company in the industry, ABEK, had been founded in 1976 by two people with 20 years of miniature ball- making experience. Unlike Pioneer, which specialized in small to large balls, ABEK specialized in miniature balls that were 1/16 of an inch in diameter or smaller. With its expertise in this area, ABEK was able to manufacture high precision balls as small as .012 inches and became a leader in this field.

It was this expertise, combined with Thomson Industries determination to have a USA supplier of high quality, that had led it to purchase ABEK in 1982. Once the purchase was finalized, approximately 14% of ABEK’s sales were to Thomson divisions. At that time, ABEK manufactured the miniature and small balls sizes, and purchased the larger sizes from Pioneer, which it then sold to Thomson. ABEK, was combined with Pioneer in 1988 to form Thomson Precision Ball. This enabled Thomson Industries to satisfy all of its’ ball requirements. Approximately 14% of Thomson Precision Ball capacity is still dedicated to Thomson Industries.
