Home of the Universal Hammer Bench

Industry leading value through dedicated service and precision parts.


J.R. Kennedy has been successfully serving the mining, material handling, mineral processing, and construction industries since our inception in 1964. Located in Tucson, AZ, we offer a wide variety of products ranging  from our proprietary Hammer Bench to manufactured product. Since the beginning we have survived on a reputation of integrity; providing excellent service and expertise. We are also a full service welding and fabrication shop.

In an effort to continue to meet the needs and expectations of our clientele both locally and abroad we have recently expanded product offerings for both the mining and recycling industries. In order to expeditiously achieve this task JRKCO entered into a joint venture in 2019 with an established overseas manufacturing organization to bring high quality products at a reasonable rate to our customers.

This cooperative consists of three partner owned fully integrated foundries as well as heat treat and a forging facilities. Our partnered manufacturing facilities bring with them over 40 years of experience and are ISO 9001:2008 / 14001:2004 & ISO/TS 16949:2004 certified. They have been providing high quality castings and forgings to global OEM’s and other industry leaders for decades. This means that our partners have had tight quality control measures in place allowing them to meet the OEM’s extremely high standards from the very beginning.
