“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.

    A Partnership is Born

    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.
