Sugatsune America's engineered stainless steel torque hinge SFTH-05-35 provides controlled positioning for industrial equipment covers, access panels, and other hinged assemblies, holding them in place at any desired angle.
With 30.4 lb·in (35 kgf·cm) of torque per hinge, the SFTH-05-35 supports larger, heavier panels. With a wide 180° opening range, the free-stop feature lets you position the lid without separate stays or support mechanisms. Even preventing the lid from slamming shut.
Technical Specifications and Performance
The friction torque hinge SFTH-05-35 incorporates the following specifications:
- Torque rating: 30.4 lb·in (35 kgf·cm) per hinge, with ±5 kgf·cm tolerance
- Material: 304 stainless steel main body with a 303 stainless steel shaft and 301 mating body
- Maximum opening angle: 180° Weight: 195 g per hinge
- Mounting: Eight mounting holes; requires 4 mm or #8 screws, sold separately
- Operating temperature: -20°C to 60°C (-4°F to 140°F)
The hinge provides friction resistance during both opening and closing, helping prevent unrestricted movement in many industrial equipment applications.
Engineering Considerations for Torque Hinge Selection
When specifying a friction torque hinge, engineers should evaluate the panel's weight, center of gravity, hinge-axis orientation, and required opening range.
The gravitational moment on the hinge depends on the panel's weight and the perpendicular distance between its center of gravity and the hinge axis. Also consider the number of hinges, torque tolerances, operating forces, and anticipated vibration.
The simplest way to calculate torque is to multiply the weight of the lid by the distance of the panel measured from the hinge side and divide by 2, or:
Torque = 1/2 x (Weight of the Panel) x (Distance of Panel measured from the hinge side)
Engineers can consult Sugatsune's CAD file resources and product drawings to verify installation dimensions and mounting compatibility.
Industrial Applications and Related Hinges
Specify the SFTH-05-35 for machine access covers, inspection panels, sheet-metal enclosures, transportation equipment, and specialized industrial cabinetry.
For assemblies requiring greater friction resistance, the SFTH-05-58 stainless steel torque hinge provides 50.3 lb·in of nominal torque per hinge.
