Ceramic bearings are compared with steel bearings:
1.Self-weight is 30% to 40% of steel bearings:It can reduce the centrifugal force of the operation, and the speed is 1.5 times of the steel bearing, the hardness is 1 times of steel, and the wear-resisting and anti-pressure is 5-7 times that of steel.The thermal expansion coefficient is less than 20% of the bearing steel.Friction coefficient is less than 30% of bearing steel, heat resistance, tensile and bending are equivalent to metal.
2.The maximum service life is five times longer than the steel bearing:Under the load, the centrifugal force decreases, the roller load decreases, the friction coefficient is small, reduces the operation temperature rise, reduces the friction, and extends the life of the raceway.
3.High speed ceramic bearing:It has the advantages of small force elasticity, light weight, small friction coefficient, high pressure resistance and cold tolerance.It can be used in the high-speed spindle and high precision equipment of 12000 RPM/min -75000 RPM.
4.High temperature ceramic bearing:Resistance to high temperature 1200 ºC, and good self-lubrication, temperature between 100 ºC to 800 ºC is not caused by temperature difference expansion.It can be used in high temperature equipment such as kiln, steel and smelting.
5.The magnetic:Ceramics are not magnetic, magnetic foreign objects and dust are not adsorbed, low noise and so on.Reduces wear and tear.Application in demagnetization, precision instrument and other equipment.
6.Corrosion resistance:Ceramics have the characteristics of corrosion resistance.Applied to chemical machinery, navigation ships, Marine operating machinery, electroplating equipment, electronic equipment and so on.
7.Electrical insulation:It can be used in insulation equipment.
8.Oil-free self-lubricity:Â The ceramic material has the characteristics of oil-free self-lubrication, which can prevent the lubrication of oil and grease and overcome the problem that the ordinary bearing cannot realize self-lubrication. Therefore, it can be used in high vacuum environment.

Gas Spring:
It consists of the following parts: pressure cylinder, piston rod, piston, sealing guide sleeve, filler (inert gas or oil and gas mixture), cylinder and cylinder control element the control element (of a controllable Gas Spring) and joint. Principle is in the closed pressure cylinder filled with inert gas or oil and gas mixture, the cavity is higher than atmospheric pressure several times or dozens of times, the cross-sectional area of the cross-sectional area of the piston rod is smaller than the piston to produce pressure difference to achieve the movement of the piston rod. Due to the different fundamental principle, the gas spring than ordinary spring has the advantages of obvious: speed is relatively slow, dynamic force changes little (within 1:1.2), easy to control.
The relative disadvantage is no small volume spiral spring, high cost, relatively short life. Unlike the mechanical spring, air spring has a nearly linear elastic curve. X between elastic coefficient of the gas spring 1.2 and standard 1.4, other parameters according to the requirements and conditions of flexible definition.
Category:
According to the characteristics and applications of different gas spring, also known as the supporting rod, air support, recliner, pressure rod, dampers etc. according to the structure and function of the gas spring to classify gas spring free type gas spring, self-locking gas spring, pull type gas springs, random stop gas spring, gas swivel chair spring damper, pressure rod,Self Locking Gas Spring,Auto Gas Spring,Industrial Gas Spring, Groove Gas Spring,Stretching Gas Spring,Office Furniture Gas Spring, etc.. Several products in the automotive, aerospace, medical equipment, furniture, machinery manufacturing and other fields have been widely used.
Structure and Function:
Gas spring is a kind of lifting spring can be labor-saving, can be divided into self locking gas spring (such as the bottom of the lifting seat backrest, boss chair, etc.) can not be self locking gas spring (lifting support such as car trunk, closet doors), the structure of the gas spring is mainly composed of a sleeve, a piston and a piston. Bar, with a high pressure air or high pressure nitrogen in the sleeve, due to the pressure difference between the ends of the piston area ranging, push the piston and piston rod movement and support people or objects.
How to Select the Right Gas Spring:
Quality evaluation of a gas spring quality mainly from the following aspects: first is the seal, if good sealing will appear in the process of using oil spills, leakage and other phenomena; second is the precision, such as the need to 500N the gas spring force, some manufacturers out of the error is not more than 2n, some manufacturers of the products may and the actual needs of the 500N is quite far; again the use of life, the life of its fully retractable count; the last is in the process of the force value change, gas spring under ideal condition should force values remain constant throughout the trip. But due to the factors of design and manufacture, the gas during the spring force value inevitably changes. But the magnitude of change is an important criterion to measure the quality of the gas spring, the magnitude of change is small, the better the quality of the gas spring, and vice versa Worse!
