Bal Seal Engineering Inc. has expanded its line of spring-energized seals to include large diameters—up to 120 inches inner diameter (ID)—for slow-speed rotary and reciprocating medical applications.
Officials for Bal Seal, a Foothill Ranch, Calif.-based provider of custom-engineered sealing, connecting, conducting and electromagnetic shielding solutions, say the one-piece, large-diameter seals offer equipment designers and end-users “excellent” resistance to wear, extrusion and chemicals. The seals are energized with the company’s proprietary Canted Coil Spring technology.
The low-friction, large-diameter seals are available in a variety of U.S. Food and Drug Administration-compatible materials, according to the company. Polytetrafluoroethylene-based seals are available in sizes up to 120 inches ID; thermoplastics, which can be incorporated into backup designs, are available in sizes up to 94 inches ID.
Company officials said the large diameters are offered to respond to growing demand for high-performance sealing options in imaging systems, such as magnetic resonance imaging, positron emission tomography and computed tomography scanners to address dynamic sealing and environmental conditions, including ambient temperature, humidity and airflow.
“For decades, we’ve been working with medical OEMs and using our unique sealing technology to help them achieve higher levels of performance and efficiency in ultrasound and other applications,” says Bal Seal Global Medical Market Manager Steve Twork. “We’re extending that experience, as well as our proven technology, to areas that are positioned for significant growth.”
