About Servometer

Servometer - PMG, LLC, of Cedar Grove, New Jersey, was established in 1957 and is a preeminent manufacturer of customer miniature metal bellows and bellows assemblies, bellows type flexible shaft couplings, gold plated bellows contacts, and electroforms. The primary material for the precision flexible bellows is electrodeposited nickel. Servometer bellows are flexible, leak tight, and can be used as springs and flexible seals in long life applications. They can be made down to a diameter of 0.040 inches. Bellows type flexible shaft couplings can accommodate axial, angular, and offset deflections with zero backlash and low windup. Gold plated contact bellows can be used in delicate electronic applications where good contact and continuity are important. Servometer precision electroforms are lightweight and structurally rigid. A design staff is on hand to help with the design of custom applications.

Today, as part of MW Components, Servometer continues to focus on honing its technical expertise and, of course, "making the impossible possible." We design and manufacture custom precision components and assemblies to exacting customer specifications. Servometer is a global leader in the production of precision electroformed bellows and related products.

Our tradition and history are built on a fundamental philosophy of hard work, honesty, and teamwork. Dedicated people providing innovative solutions to serve ever-changing times have built the company. From the early 1960's when our products were part of NASA's Telstar Satellite Program, until today, providing precision parts for the United States Air Force air combat missiles and the Space Shuttle Program, Servometer has remained the benchmark of the industry. Today, Servometer provides products and services to a growing global market.

Our Manufacturing Services

Servometer is dedicated to advancing technology across numerous and diverse markets worldwide and takes pride in developing the highest level of quality products from design, through production, to delivery.

  • Servometer offers prototypes or sample parts for a variety of custom components including springs, fasteners, bellows, couplings, and other precision metal parts. We also offer rapid prototyping for select components, with shipping in as little as one week.

  • Electronic Beam Welding

    Electron-beam welding fuses materials together using high-velocity electrons focused into a beam, causing the materials to melt, merging the two pieces into one.

  • Soldering

    Soldering joins two or more materials together by filling the joint between the two with a melted filler metal. Unlike traditional welding methods, soldering does not require melting the original materials.

  • Plating

    Plating is a manufacturing process where a thin coating is applied to a component’s surface through chemicals or electric current (electroplating).

  • Would you like to make your overall production process more efficient? We offer part assembly services with both new and existing components. Ship your coordinating parts to us, and we’ll put them together according to the requirements and timeline you specify.

  • Cycle Testing

    Cycle testing, or life cycle testing is a process where products are tested to ensure adequate life cycle or product lifetime under regular working conditions.

  • Optimize your designs to reduce cost, improve performance, and accelerate time to market.
