Welded metal bellows are produced with a lower initial tooling cost and maintain higher performance characteristics. The drawback of welded bellows is the reduced metal strength at weld joints, caused by the high temperature of welding. [1] Electroformed bellows are produced by plating (electroforming) a metal layer onto a model (mandrel), and ...
U.S. Bellows, Inc. provides a variety of expansion joints for piping and duct systems [2] and has been a member of the Expansion Joint Manufacturers Association, Inc. since 2002. [3] In December 2011, U.S. Bellows acquired all bellows assets of the former Lortz Manufacturing companies, doubling its manufacturing capabilities. [ 4 ]
Diagram of a fireplace hand-bellows. A bellows or pair of bellows is a device constructed to furnish a strong blast of air.The simplest type consists of a flexible bag comprising a pair of rigid boards with handles joined by flexible leather sides enclosing an approximately airtight cavity which can be expanded and contracted by operating the handles, and fitted with a valve allowing air to ...
A 48 V system can provide more power, improve energy recuperation, [7] and allow up to an 85% decrease in cable mass. [10] 12-volt systems can provide only 3.5 kilowatts, while a 48 V power could achieve 15 to 20 kW or even 50 kW. 48 volts is below the level that is considered safe without special protective measures.

Stainless steel was widely used for springs, retainers, sleeves and glands. Single and multiple seal arrangements were used as necessary to accomplish the required performance. In 1957, Sealol introduced the edge welded metal bellows seal. Previously, metal bellows seals had used a formed bellows which was much thicker and stiffer. [7]
Weston Miller Fulton (August 3, 1871 – May 16, 1946) was an American meteorologist, inventor, and entrepreneur, best known for his invention, the "sylphon," a seamless metal bellows used in thermostats, switches, and other temperature-control devices. [1]

Telescopic cylinders are a special design of a hydraulic cylinder or pneumatic cylinder as well as pulley system which provide an exceptionally long output travel from a very compact retracted length. Typically the collapsed length of a telescopic cylinder is 20 to 40% of the fully extended length depending on the number of stages. [1]
