Servometer® / PMG, LLC designs and manufactures precision, electrodeposited nickel bellows, bellows assemblies, flexible shaft couplings, electrical contacts and lightweight, structurally rigid electroforms.
Servometer custom designed miniature nickel alloy metal bellows can be made as small as .020 inch (.5 mm) in diameter and still retain full sensitivity and flexibility. Seamless and non-porous; no dust, dirt, or moisture can lodge in seams and cause contamination in critical applications. Servometer bellows are leak tight to 1 x 10-9 std. cc/sec., and can be designed for “infinite” life expectancy (100 x 106 cycles). They offer superb performance in applications such as metallic hermetic seals, volume compensators, pressure and temperature sensors, flexible connectors, and countless other applications where quality, reliability and long life are critical requirements.
Servometer zero-backlash, flexible shaft couplings meet rigorous needs in precision rotary positioning systems, where high flexibility, sensitivity and extreme accuracy in dimensional tolerances and concentricity are critical. Our stock line of bellows-type flexible shaft couplings have a torque range from 1.4 Ncm to 198 Ncm. Outside diameters range from .252 inch (6.4 mm) to 2.40 inch (61 mm) and overall lengths from .5 inch (12.7 mm) to 2.44 inch (62 mm). Larger sizes and greater torque capabilities are available on a custom basis.
Servometer self-aligning spring contacts meet critical solderless connection needs in miniature electronic applications, and feature negligible insertion and inductance loss. They are ideal for repetitive connect and disconnect. Outside diameters range from .037 inch (1 mm) to .245 inch (6.22 mm) and are available from stock. Custom contacts can be designed with bellows diameters as small as .020 inch (.5 mm).
Servometer lightweight, structurally rigid electroforms are the ideal solution for needs involving unusual shapes, close tolerances, high strength and ultra-thin walls, and can withstand extreme temperatures down to -423° F. Diameters range from .020 inch (.5 mm) to 9 inch (229 mm). Surface micro-finishes as fine as 4 R.M.S. are also available.
