Bal Seal Engineering, Inc. is a designer and manufacturer of mechanical seals and springs. Established in 1958 in La Habra, California, the company specializes in designing canted coil springs used for fluid sealing, mechanical connecting and electrical conducting. Headquartered in Foothill Ranch, California since 1998, the company is privately owned and operated, and employs over 600 people worldwide.
History[edit]
Bal Seal Engineering was founded in 1958 in La Habra, California[1] to produce a new type of mechanical seal which combined a polytetrafluoroethylene (PTFE) jacket with a canted coiled spring as a longer lasting alternative to conventional o-ring seals. The company’s founder also discovered that the canted coil spring could be used to address multiple mechanical engineering and design challenges. The spring’s deflective properties could be applied to mechanical sealing, and it could also manage current with high power density and minimal heat rise, thus eliminating the need for multiple components and reducing equipment complexity and weight.
The company has since expanded its offering to include solutions for fluid sealing, mechanical connecting, electrical conducting and EMI shielding/grounding applications. To meet demand, Bal Seal Engineering opened a new production facility in Colorado Springs, Colorado in February, 2014[2].
Patents[edit]
Bal Seal Engineering has pioneered canted coil spring technology, filing the first patent for the canted coil spring in 1987[3]. Since then, intellectual property and patents have been an integral part of the company with over a hundred patents granted.
Some notable patents include:
- US Patent 4,655,462 “Canted coil spring and seal”: Original Canted Coil Spring Patent. Describes the features of the canted coil spring, unique characteristic of near-constant force during deflection, and highlights excellent performance for use to energize seals.
- US Patent 8,167,285 “Spring latching connectors”: Covers the use of canted coil spring for providing mechanical latch connection between two parts. Includes a wide array of spring types, groove designs, and connector configurations.
Notable Applications[edit]
Today, Bal Seal Engineer's products are used in a variety of notable technologies:
- Tesla Motors electric car springs[4]
- Wind turbine environmental protection seals and connectors[5]
- Cardiac pacemaker electrical contacts[6]
