What Are The Common Types Of Swing Door Hinges?
revolving doors have many hinges, and their design focuses on the door's movement, load bearing requirements and usage scenarios. The following is a detailed analysis of the types, characteristics, applications and typical examples of common rotary common revolving door hinge types:
I. By means of mobility
1.Fixed-Axis Hinge
Features:
The door rotates on a fixed axis with a circular or curved motion. The hinge structure is simple and stable.
Single-Axis Hinge: It has only one rotating shaft and is suitable for small doors (such as interior partition doors).
Dual-Axis Hinge: It has two axles, one on top of the other, which enhances the wind resistance of the door and is often used in large revolving doors.
Application:
shopping malls, hotels, airport double or triple winged revolving doors and small curved display cabinets.
Typical examples:
Hettich's dual-axis revolving hinge that supports 360 rpm and has a load capacity of up to 80kg.
2.Sliding Revolving Hinge
Features:
Combining the function of push and pull door and rotating door, it can bend or rotate in the course of sliding line, eliminating displacement differences. "1 Fixed + 2 Rotating" Combination: Fixed hinges maintain the door in position while rotating hinges adapt to a curved trajectory.
Adjustable Angle: Restrainers on rotating hinges are screwed in to control the door's bending angle (e.g., 90°, 180°).
Application:
Industrial equipment doors, logistics access door, space dividers custom.
Typical examples:
Japan's DTC sliding rotary hinges use nylon cushions to reduce sliding noise.
3.Automatic Return Hinges
Features:
Once released, the internal spring or hydraulic mechanism automatically returns the door to its original position without having to close it manually.
Spring: A torsion spring provide recoil, lower cost, but shorter service life.
Hydraulic oil: Hydraulic damping provides a slow return leading to a quiet and durable design.
Application:
Hospitals have accessible doors, fire doors, and doors to public areas that often open and close. Typical examples:
Blum's hydraulic automatic return hinges provides 200,000 open rings and adjustable speed from Germany.
ii. By Structure Type
4.Exposed Hinges
Features:
Hinges were exposed to the exterior of the door for easy installation and maintenance, but not pretty.
Material: Generally made of stainless steel or cold-rolled steel, with chrome-plated or spray paint rust resistance.
Application:
Industrial warehouse doors, temporary partitions, aesthetics don't matter.
Typical examples:
GUTE's exposed stainless steel hinges hold up to 50kg and are affordable.
V. Concealed Hinges
Features:
Hinges are embedded in doors and frames to make them look simple and suitable for high-end applications.
3D adjustment: support up and down fine tuning, left and right fine tuning, before and after fine tuning, to ensure perfect coordination.
Quiet Design: Nylon or rubber cushioning are used to reduce opening and closing noise. Application:
Five-star hotel revolving doors, luxury store display cabinets, smart home door.
Typical examples:
Salice's invisible hydraulic hinges open and close at 175 degrees and offer excellent sound suppression.
III. By Special Functions
6. Anti-Pinch Hinges
Features:
The hinge hinge edges are rounded or have built-in infrared sensors that automatically stop spinning or bouncing when the barrier is detected.
Passive Protection: Physical propertiessuch as rounded corners and elastic rods reduce the risk of being squeezed.
Active protection: Integrated sensor and motor, provides intelligent clamp protection.
Application:
Kindergartens, schools, nursing homes, etc., have children and elderly.
Typical examples:
response time of Häfele (Germany) intelligent anti-lock hinges ≤ 0.2 seconds.
7. Low-Temperature Hinges
Features:
Special grease and sealing structure ensure flexible rotation even at -40°C.
Material: Stainless steel or engineering plastics, brittle. Application:
Cold storage doors, equipment hatches and cryo-lab doors doors at polar research stations.
Typical examples:
Southco's low-temperature hinges, tested at -50C.
8. Fire-Resistant Hinges
Features:
material wrapping or interior design can maintain structural integrity at high temperatures and prevent the spread of fire.
Accreditation criteria: meet EU EN 1634 or US UL 10C fire test requirements.
Application:
Fire doors, data center computer room doors, high-rise building security doors.
Typical examples:
Union's fire-resistant hinges lasts 90 minutes.
IV. INTRODUCTION Introduction by Load Capacity
9. Lightweight Hinges
Features:
Capacity 5-15 kg, suitable for small doors or light materials (e.g. glass, acrylic, etc.).
Material: Engineering plastic or thin steel plate, low cost.
Application:
Indoor display cabinets, small pivoting partitions, smart home device doors. Typical examples:
Kinlong's lightweight plastic hinges cost just 2-5 yuan per unit in China.
X. Heavy-Duty Hinges
Features:
Load capacity 20-100kg or above, thick steel plates, reinforced bearing, good abrasion resistance.
Material: Cold rolled Cold-rolled galvanized steel or stainless steel, rust resistant surface.
Application:
Large revolving doors, industrial equipment hatches, logistics entrance and exit doors.
Typical examples:
Söke's heavy-duty stainless steel hinges from Germany has a capacity of 120kg and a service life of more than half a million times.
In a word: how to choose a Revolving Door Hinges
Action: Choose the appropriate hinge type, depending on whether the door is purely rotating, sliding or requires an automatic return trip.
Structure: Choose hidden hinges aesthetically; choose exposed hinges to save costs.
Features: Select functional hinges (e.g. pinpoint protection, fire protection, low temperature protection) according to application requirements. Load-bearing capacity: The weight of the door plus external pressure (e.g. wind pressure) shall be less than 80% of the hinge's rated load.
Brand and budget: High-end apps choose imported brands such as Blum and Hettich. If the budget is more limited, choose high-quality local brands (such as Dongtai, Jianlong, etc).
