Message from the Founder

After working in the industry for 12 years, in 1990 I decided to open a hydraulic cylinder repair facility. I noticed early on that there was opportunity in cylinder manufacturing; with that in mind, in 1996 we rented another space a few blocks away, purchased some additional equipment and started manufacturing cylinders, mostly for local equipment manufacturers.

By 2000 we had out grown both our repair and manufacturing facilities so we purchased the building that RHK is presently occupying. In 2003 we added onto the building to expand our Chroming Facility and in 2014 we added onto our machine shop. This gives us about 30,000 square feet of shop space and 2000 square feet of office space.

Many of the lessons that I learned during that time was to treat employees, suppliers and customers with fairness and respect. Those are values I have always deemed important and we continue to value at RHK today.

As you are viewing this website you may have a requirement for our products or services. Please contact us with any requests for any hydraulic cylinder manufacturing, repair or  any processes that we have to offer.
