Bal Seal Spring-Energized Seals
Our Bal Seal Spring-Energized Seals, machined from Polytetrafluoroethylene (PTFE) and other premium polymers, are energized with a custom-engineered Canted Coil Spring. Exerting a near-constant force over a wide deflection range, our seals ensure more even, consistent wear and longer service life.
The seals are ideal for a variety of different applications, including rotary, reciprocating, static and oscillating. The seals can be custom-engineered to meet your specific requirements for friction force, durability, temperature resistance and longevity, and we offer larger diameter seals of up to 120 inches.
Bal Seal Spring-Energized Seals can be found in a number of unmanned vehicle applications, such as hydraulic systems in landing gear, exclusion of moisture and debris in UAV actuators, and leakage prevention in fuel control valves.
