Gas Strut for the Automobile Industry
Gas strut makes operations very easy in Automobile Industry. Peir International teams are of well experience to help select the right gas spring. Gas Spring Applications Gas strut is basically useful and convenience for vehicles, like soft boot /bonnet opening even for Heavy SUVs and trucks.Jeep, SUVs and truck are using smart operations by remote […]
Viscous Rotary Damper2
The damping coefficient of the rotary damper is defined by viscous resistance.Hydraulic rotary motion dampers use silicon oil as the damping fluid medium to generate different damping torque.The unit for silicone oil viscous is mm2/s (cSt). Rotary damper manufacturers need to purchase various models of damping oil to meet different torque requests. One damping oil […]
How rotary dampers provide damping effects
While rotary damper is used, we wonder how rotary damper works? Gear dampers Due to the invisible braking effect of the viscous grease on the rotating body, the viscous grease in the body produces a damping force on the movement of the moving parts. The size of the torque is determined by the viscosity of […]
Gas spring end fittings and mounting brackets
Here you will find a complete collection of the most frequently used gas spring (gas strut) end fittings and brackets with standard sizes. The mounting method can vary in applications. Different end fittings and brackets configurations are available for your choice. End fitting common types are Ball joint, eyelet, clevis forks, etc. Different material options […]
How do you size a rotary damper?
Rotary dampers an support us when we want to find a soft-moving solution for the product. Typically, there are two situations. The cover lid can fall free because of gravity. However, the lid may plunge suddenly. We can install rotary dampers to make the top lid close softly. The cover lid can be opened because […]
How to calculate the required gas spring force?
Gas spring pressure/force calculationThe pressure required for the gas spring is calculated by substituting the value used in the following formula: F1 = ((m* RH)/(2* N* x2) +5)* 9.81 = gas spring pressure (Newton)F1 = gas spring pressure/forceN = number of gas springs requiredm = weight of the tailgate/object to be lifted, operated (kg)RH = length […]
How to choose the right gas springs– force decision
In our last video, we introduced how to measure a gas spring, how to measure two lengths and two diameters. And normally, we can see the force on the surface of the gas spring. But we can also know the required gas spring force by calculation. Next, let me introduce how to calculate the force. […]
Rotary damper adjustable
Rotary damper is suitable for almost any application. Peir supplies damper torque varies from 20gf.cm to 135,000gf.cm. Rotary damper’s specification is fixed once produced. Let’s say for example, its specification is 30±10gf.cm. So what means ” adjustable rotary damper”? For a certain model, it is available in adjustable variations. The viscous grease in the body […]
Instructions of attention in the use of rotary damper installation
Rotary damper is of small size and delicate structure, so we must put some instructions to damper installation or use. We have to apply it properly and avoid mechanical damage. Please read attention notes carefully before rotary damper installation or use. Do ensure the installation strength of counterpart In case of poor strength, your application […]
Coding method on gas spring models
The code of gas spring model, in general, composes of the following important parts. They include type code, the diameter of the piston rod, the outer diameter of the cylinder, the stroke, the extension length, and the end fittings. Besides, the working method, the end joint fitting, and the small expansion force are all necessary […]
