Product Spotlight – Rotor-Stator: Torque Butt-Hinge (50×50 Preset Model)
Control Lid Movement in Professional Builds
In service bodies, toolboxes, vehicle canopies, and hinged enclosures, unsupported or disproportionate lid and/or door movement can cause:
- Doors that fall freely and/or slam, risking damage or injury.
- Misalignment affecting seals, allowing dust, water, and vibration to cause fatigue.
- Inconsistent torque from replacements, making specification and maintenance difficult.
Professionals need a hinge that holds doors in place, resists vibration, and provides predictable movement across thousands of cycles.
An Entry-Level Solution: 50×50 Preset Torque Hinge
The 50×50 Rotor-Stator torque butt-hinge delivers controlled movement with symmetric preset torque (2 Nm), ideal for lightweight lids and access panels in applications where gas struts are not feasible or desired. Its rotary-static design ensures that movement is borne by the moving leaf (rotor), protecting the frame and welds.
Key Features and Benefits
-
Rotor + Stator Design: Rotor leaf moves, stator fixed — ensures consistent, reliable torque.
-
Preset Torque: Symmetric 2 Nm torque holds doors or lids in desired positions.
-
Compact 50×50 mm Form Factor: Suits smaller panels, mobile service compartments, and tight-fit applications.
-
Full Range of Motion: Up to 180°, allowing predictable swing and retention.
-
High Cycle Life: Designed for 25,000+ opening/closing cycles.
-
Robust Materials: Zinc alloy body, steel pin, black textured powder-coated finish.
- Flexible Installation: Front or rear fixing; left/right-hand orientation supported.
Pro Tip: Perfect for lightweight lids where controlled hold-open and gentle closing are required without additional adjustments.
