Products for Transportation
Bal Seal® Spring Energized Seal
Our seals are precision-machined from PTFE and other premium polymers, and they’re engineered to deliver longer service life and more equipment uptime for the transportation industry. Their spring energizers ensure even, consistent wear, and their jacket materials can be customized to meet specific requirements in dynamic and static sealing applications.
- Controllable friction forces
- Excellent media and temperature resistance
- Wear-regulating spring energizer
Bal Spring® Canted Coil Spring
Our spring mechanically fastens, conducts electricity, and shields sensitive electronics from EMI/RFI. Its independent coils, which serve as multiple contact points for optimal current carrying capability, ensure consistent, reliable connection—even under shock and vibration.
- Superior conductivity & power density
- Compact, space-saving profile
- Multifunctional for lighter, simpler designs
- Customizable insertion/removal forces
