Lesjöfors Springs America, Inc.

As an industry leader in the design and manufacture of custom engineered flat mechanical springs and spring assemblies, Lesjöfors Springs America, Inc. has the proven ability to satisfy the requirements of the most demanding customer applications, while offering the assurances of exceptional quality, performance, and customer service. 

Our heritage in spring manufacturing extends back to 1926 when we supplied clock springs for the watch industry.  Since then, we have matured our flat strip spring manufacturing processes to provide a myriad of products for varied customer applications based on torque and turn requirements.

Operating two North American manufacturing locations in Pittson, Pennsylvania and Nogales, Mexico, we are strategically positioned for favorable delivery lead times, competitive product offerings, and strong customer relationships.  Our world class customer service, engineering support, and commitment to continuous improvement form the foundation of our business and help ensure customer satisfaction.

We provide customized solutions using design capabilities that feature our advanced, proprietary spring design software.  We also offer performance testing that allows for rapid production of spring prototypes to help our customers achieve a competitive advantage by improving their speed-to-market.

By providing expert metallurgical knowledge with long experience in spring production, we have the expertise to optimize spring design, which will contribute to better end-product performance for our customers.


Our product portfolio includes a wide variety of flat spring categories such as constant force springs, constant torque springs, hair springs (clock springs), power springs, and reels.  All products are designed and manufactured to each customer's unique performance and size requirements.


From small electronic and precision instrumentation springs to large industrial springs, we confidently serve engineers and buyers of OEM and replacement spring components in almost every area of apparatus and equipment manufacturing.  Applications for our springs include automotive, appliance, cord reels, cable reels, defense, elevator door closures, fall safety restraints, hose reels, outdoor power equipment, tool balancers, window balance systems, and other specialized retraction and counter balance systems.


For over 40 years, our manufacturing operations in Scranton, Pennsylvania have produced the finest quality power springs for a wide array of steadily growing applications.

In 1989 we expanded our manufacturing capacity through the strategic addition of our Nogales, Mexico plant.  This helped improve customer accessibility to our products, and afforded us new opportunities within a number of growing industries.

Today, both plants operate in a highly flexible, 24-hour lean manufacturing environment and conform to strict ISO 9001:2008 standards.  We offer complete design and fabrication services for our customers, and our manufacturing and customer service boast the following capabilities.
