“RIGHT THE FIRST TIME” is what Timothy Bowgren had in mind when he established Five Star Hydraulics in 1977.

  • 1977

    Our Humble Beginnings

    Initially started as an emergency repair facility Five Star has grown to become a leader in custom hydraulic and pneumatic mill duty cylinder manufacturing and reconditioning! Five Star Hydraulics, located in Portage, Indiana began serving the steel industry in 1977.  From our humble beginnings we have grown into a multimillion dollar company supplying many diverse industries from automotive, steel, high-pressure aluminum die casting, agricultural and marine to name a few. In  1977, Tim Bowgren, owner and CEO, saw a need for a quality cylinder reconditioning facility to serve the local steel industry. After working at Midwest Steel himself and experiencing first hand the void of a qualified, service oriented shop, Tim took his vision and started the company with just a handful of employees in a small building at our current location. That original building now houses only our weld shop.

    Nambu Partnership

    Nambu Co. Ltd., Tokyo, Japan, proudly announces their business partnership with Five Star Hydraulics, Inc. of Portage, Indiana, USA, in October of 2001. Mr. Kazushi Nomura, President of Nambu Co. Ltd. And Mr. Timothy K. Bowgren, President of Five Star Hydraulics, Inc. are enthusiastic about their business venture, broadening service for both the steel and auto industries. The two companies in a joint effort will provide the steel and auto industry with a multitude of experience and technology expertise in providing quality repair and manufacture of air and hydraulic cylinders. Nambu Co., Ltd., established in 1965 prestigiously supplies cylinders to first-rate corporations worldwide, specifically for the die cast and plastic mold industries. Several steel manufacturers have adapted Nambu brand rotary joint cylinders into their production lines. The Nambu rotary joint has proven to be more durable and works more smoothly alleviating timely maintenance and downturn. At the present time, Five Star concentrates on the maintenance and repair of the rotary joint, which is the base of sales expansion in the steel industry. Five Star has built a $250,000 “clean room” inside their existing facility for future business of the rotary joint cylinder repair.

    Expansion to the South

    In June 2015, Five Star Hydraulics opened their first satellite repair center in Blytheville Arkansas. With the growing steel business in the region, Five Star expanded into the South to service a growing customer base. Our focus is to service the industry with better logistics that will in-turn translate to a cost and delivery savings to the customer. Our fully equipped hydraulic repair and machine shop services the local steel, pipe & tube, agricultural, marine terminal, and auto die cast industries while also supporting our partners of NSD sensors and Nambu products. We are a service oriented business performing at a level of excellence to provide our customers with value. We offer thorough inspections, detailed reporting, failure analysis and recommendations on all our jobs. From emergency situations to routine maintenance, we are here to service our customers.

    Nambu Agreement is Renewed

    In September 2016, Takahide Nomura, President, Nambu Co., LTD. and Tom Follis, President, Five Star Hydraulics, Inc. signed an updated “Distributorship Agreement” to renew and strengthen the relationship between our respective companies. Working together we will further the sales expansion of the rotary joint and expand/collapse cylinder for the coilers in the steel industry in North America. Regarding the core pulling cylinders for the aluminum die-casting industry, which is the main product of Nambu, Five star Hydraulics will now have a large inventory of standard seal kits in order to respond to customer’s needs in a timely and cost-effective manner. We also stock related rebuild parts for the customer to be able to overhaul on site as necessary. With our clean room testing facility, parts inventory and ongoing training, we are striving to meet our customer’s needs in every way. The signing of this agreement comes 15 years after the original, which was signed by the previous presidents of both companies and displays the commitment to continue a strong relationship and build on the success of the past.
