Message from the Founder

Thank you for viewing our website, we have designed it to help you understand what we do and where we are going.

I started RHK in 1990 after working in the Industry for 12 years. Many of the lessons that I learned during that time was to treat employees, suppliers and customers with fairness and respect. That is a core value that I always deemed important.

RHK started as a Hydraulic Cylinder Repair facility and I noticed early on that there was opportunity in Cylinder Manufacturing. With that in mind, in 1996 I 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.

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 Repair or Supply. Or any processes that we have to offer.
