A new test service introduced by Bal Seal Engineering offers verified performance results for Bal Seal® low-friction spring-energized seals used in rotary/face applications. The test is designed specifically to evaluate performance of its low-friction polymer-filled polytetrafluoroethylene spring-energized seals, designed to minimize “stiction” to facilitate smooth rotation and bi-directional motion, used against a range of material hardnesses/finishes.
Rotary/face seals are frequently used in dynamic housings and mounts to protect electronics and other internal components from environmental contaminants. To minimize stick-slip and meet motor torque requirements, these seals must exhibit very low friction – but they must also minimize leakage over long periods of exposure.
According to the company, the service will help OEMs and tier suppliers eliminate unnecessary costs, delays and complications associated with in-house or outsourced seal testing.
For orthopaedic devices and medical instruments, Bal Seal supplies FDA-compliant sealing and connecting solutions with technology ranging from seal applications for high-speed surgical hand tools to springs for tool-less connections. The Bal Springâ„¢ canted coil spring shields diagnostic instruments from the harmful effects of EMI, while its customizable insertion and removal forces support its use in orthopaedic and surgical instrument fastening applications.
