ST - Constant Torque Embedded Hinges

The all-metal ST series hinges deliver rugged, long-lasting, high-torque performance in a compact package.Base designs are available in multiple size, configuration, and torque variations to satisfy a wide variety of application needs.

  • Reliable positioning torque eliminates the need for secondary mechanical supports
  • Compact package allows hinges to be bolted or molded directly into a thin-profile product housing for a more pleasing aesthetic design in even the smallest applications
  • Constant-torque design is unaffected by normal temperature variations and maintains consistent performance without maintenance or adjustment
  • A range of sizes and torque-values accommodate application designs
  • Compact package allows hinges to be bolted or pressed into a thin-profile product housing for a more pleasing aesthetic design in even the smallest applications
  • Contact Southco to discuss customization options
  • Minimum cycle performance: 20,000 cycles ±20% of static torque specification
  • Operating temperature range: -20°C to 65°C (-4°F to 150°F)
