Product Specifications
- The maximum open-close angle is approx. 120 degrees.
- The rotation of the vanes compresses the oil and generates control (brake) force to act against work force.
How to Select
The lid in a horizontal position generates maximum torque as shown below.
Calculate maximum torque according to the following formula before selecting a damper that satisfies the specifications.
[Formula]
Maximum torque T = L/2 × m (weight kg) × 9.8 (Newton N)
Example) When L = 0.4 m and m = 5 kg
Max. torque T = 0.4/2 × 5 × 9.8 = 9.8 N⋅m
* MSDH10 is selected.
*) The selection made by the calculation above is for reference only.
The friction resistance and the effect of inertia moment at the hinge were not taken into consideration in the example above.
The viscosity of the oil in the damper changes depending on the temperature of the operating environment.
Generally, the damping characteristic decreases with rising temperature, whereas it increases with lowering temperature.
Precautions
- Custom-made items cannot be manufactured.
- Using it vertically is not recommended.

Description/Basics
Hinge
Hinges are among the fittings and are intended for movable storage. Similar to a joint, a hinge enables a bending, pivoting or folding movement. In principle, hinges are differentiated into a detachable hinge and an inseparable hinge. The separable hinge is also called a plug-in hinge. The advantage of a hinge is that the flap or door can be unhooked without great effort. Hinges are often used for maintenance doors, cabinet doors and windows. The hinge pin or hinge bolt serves as a connecting piece and axis of rotation at the same time. In most cases, the hinges are fastened using a screw connection, but hinges can also be welded to the hinge strap (flap/wing) in a permanent manner. When welding hinges, thinner sheet metals can deform due to the heat generation. Therefore, the screw version of the hinges is recommended for thinner wall thicknesses. You can buy many different hinges in the MISUMI online shop.
Spring hinge
Spring hinges are usually rolled sheet metal hinges that are preloaded with a torsion spring. The spring hinge can support an opening or closing of a flap, depending on the application. The clamping force generated increases as the angle of the spring hinge increases. Spring hinges can also support a reset function. Thus, spring hinges can also help to reduce the number of components in some applications.
Materials
The MISUMI hinges are available in aluminum, plastic, stainless steel, steel and a zinc alloy. You can order these in the MISUMI Hinge Shop as flat sheet metal hinge and in stainless steel plate, up to extruded heavy-load hinges.
Coatings
The various treatments and surface treatments such as: polished, lightly polished, brushed, sand blasted, mirror polished, stove enamelled, anodized, nickel-plated, chrome-plated are available to you at MISUMI. With these coatings, the hinges are optimally protected against corrosion and always offer a suitable appearance with the versatile surface treatments.
Installation Information
To achieve smooth operation, it is essential to align the hinge. Therefore, an exact drilling pattern is necessary for the installation. For fine positioning, MISUMI offers elongated-hole hinges, which enable easy adjustment of the elements. After the correct position has been set, the screws can be tightened with a torque wrench. For longer hinges, the screws should be tightened from the inside to the outside so that the base of the hinge fits evenly.
Maintenance
Maintenance plays an important role in the ease of movement and long service life of a hinge. Prior to lubrication, a hinge should be cleaned of old lubricants and contaminants. After lubricating, the hinge should be moved several times so that the lubricant is evenly distributed in the eyelet and hinge bolts. Which lubricant is suitable depends on the respective application and environmental influences. For commercial applications, graphite oil is often used.
