Sugatsune’s extensive range includes torque hinges, swivel hinges, damper hinges, lift -assist hinges, detent hinges, concealed hinges and more. With 90 years of expertise, Sugatsune has been developing innovative motion control concepts to provide customers with greater safety and convenience.

Torque hinges: “Free-stop motion” for holding doors, lids and stays in any open position.
Detent hinges: “Detent motion” for holding doors, lids and stays at a prefixed angle.
Damper hinges: “Soft motion” for controlled closing.
Lift assist hinges: Spring-mounted “assist motion” for lifting heavy lids with ease.
Lateral opening hinges: “Unique motion” for a compact and smooth opening of the door in a small space.

Torque (Friction) Hinges

Torque hinges are ideal for holding panels, covers, machine doors or display devices in a fixed position, even in environments with movement or vibration. Sugatsune offers a wide variety of torque hinges with different torque values, shapes, specifications, and functions to ensure safety, precision and longevity for medical equipment, machinery, transportation, and food processing machinery.

Clean design: Torque hinges allow lids or flaps to remain open at any angle without any additional stoppers or lid supports.

Enhanced Safety: By preventing lids or machine covers from slamming shut, torque hinges improve safety in industrial environments.

Convenience: Lids, flaps, display screens remain open at any desired angle, enabling single-handed operation and precise positioning.

Highlight Product: HG-TQU15 One-Way Concealed Torque Hinge

Designed to deliver friction (free-stop function) only in the closing direction of the lids or doors, and frictionless (smooth) motion while opening.
Hinge is hidden (concealed) once the door is closed.
Can be applied both horizontally or vertically.
Opens up to 90˚.
Durability: successfully passed 20,000 open/close private cycles.
Ideal for medical or analytical equipment, automation devices, and various manufacturing devices.

Swivel Hinges

A swivel hinge is a type of hinge that can rotate 360° around its axis. When combined with a free-stop mechanism, the swivel torque hinge holds its position at any desired angle to provide controlled movement and positioning. These hinges are commonly used in movable parts of devices such as tablet stands or displays and rotating control panels of machine tools.

Highlight Product: HG-S-HR50 High Rigidity Swivel Torque Hinge

A high rigidity swivel torque hinge for unbalanced loads.
Enables control panels and monitors to rotate 360° and to be held at any angle.
Hinge can be installed vertically or horizontally.
Center hole for easy cable management.
Durability: 30,000 open/close cycles passed (private test)

Damper Hinges

Damper Hinges absorb the shock to automatically and quietly close the doors without additional door dampers or closers. Sugatsune’s Damper (Soft-Close) Hinges come in various types with different degrees of dampening force.

Benefits of using Sugatsune’s Soft-Close Hinges:

Enhanced safety: The soft-close function reduces shock for internal devices and prevents finger pinching.
Convenience: The self-close function helps to keep doors in a closed position and prevents doors from opening.
Easy to adjust: The closing speed can be easily adjusted (with a hex key).

Highlight Product: HG-JV65-S Soft-Close Hinge

Soft and self-closing hinge for quiet and safe door closure.
Thanks to its adjustable closing speed, allows precise, machine-friendly door movement.
Firmly holds doors closed to prevent gaps.
Can be installed on aluminium slot profile frames for machine equipment.
Passed 50,000 open/close cycle tests (private).
