Sugatsune America's stainless steel torque hinge SFTH-03-9 provides controlled rotational resistance for industrial equipment covers, access panels, and hinged enclosures.
With af rating of 7.8 lb·in (9 kgf·cm ) per hinge, the SFTH-03-9 holds appropriately sized lids and panels at any angle throughout its 180° operating range and won’t slam shut.
Technical Specifications and Performance
The friction torque hinge SFTH-03-9 features the following specifications:
- Torque rating: 7.8 lb·in (9 kgf·cm) with ±2 kgf·cm tolerance
- Material: 304 stainless steel body, 303 stainless steel shaft, and 301 stainless mating body
- Finish: Polished
- Maximum opening angle: 180°
- Weight: 51 g per hinge
- Mounting: Five mounting holes; 3.5 mm or #6 screws required, sold separately
- Operating temperature: -20°C to 60°C (-4°F to 140°F)
The hinge provides friction resistance during opening and closing, supporting controlled positioning throughout its operating range.
Engineering Considerations for Friction Torque Hinges
Proper hinge selection requires evaluating panel weight, center of gravity, hinge orientation, and the torque needed to maintain the desired position.
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)
Review Sugatsune's CAD file resources and product drawings to confirm dimensional compatibility.
Industrial Applications and Related Torque Hinges
The SFTH-03-9 may suit machine access covers, inspection panels, equipment enclosures, and lightweight industrial assemblies.
For applications requiring greater resistance, consider the SFTH-03-19 stainless steel torque hinge, rated at 16.5 lb·in.

Stainless Steel Torque Hinge - SFTH-03-9 FAQs
What is the torque rating of the SFTH-03-9 stainless steel torque hinge?
The SFTH-03-9 provides 9 kgf·cm (7.8 lb·in) of nominal friction torque per hinge, with a ±2 kgf·cm tolerance.
Is the SFTH-03-9 friction torque hinge adjustable?
No. The SFTH-03-9 features a fixed torque rating. Engineers should verify load requirements and hinge orientation before installation.
What industrial applications can use the SFTH-03-9?
The hinge can be used in industrial equipment covers, inspection panels, sheet-metal enclosures, and access doors that require controlled positioning, provided the applied load stays within the hinge's operating capabilities.
