At R&J Cylinder, we don’t just place an emphasis on one aspect of our business. We deliver the utmost craftsmanship and precision machining that our customers require, along with the highest quality customer service in the industry. It is what great customers deserve, and great companies provide.

High Standards Since 1990

R&J has been meeting these expectations since 1990, when we opened our doors in a small garage in Dover, Ohio. Today, with over 120,000 square feet of production capacity, we utilize the most advanced CNC machines and lathes to provide our customers with the exact specifications their projects demand, all at a competitive price.

And our people? In our business, expertise is what sets us apart, and with over 100 years of combined experience, we provide customers with the attention and care they need to ensure success. Regardless of position, our family of employees are equally passionate and dedicated to delivering the highest standards of quality and care available in the marketplace.
