Product Description:

1.Description of Oil Seal:

As we know that there is some oil would go-in the rubbing parts of the machine usually and in order to resistant against this oil we need to use the oil seal to seal the gap of the machine. More than that, we have to concern to how to seal the water, chemical liquid and the dust, all of these environment calls for the oil seal.

2.Main features of Oil Seal:

Waterproof/oilproof/dustproof/wearproof/airproof

Heat/cold/chemical/Ozone /wearing resistant

Anticorrosion/antiage/anti-friction

Multiple styles/colors/models(more than 4000)

Q:How to prevent the metal from sticking to the gasket?
Gasket and flange sealing surface should be cleaned, must not have any influence on the sealing performance of scratches, spots and other defects exist.
Q:What are the cylinder seals?
Other static seals, located in the end cover, ah, cylinder above a few, the requirements are not high.- the drawings are a simple hint.
Q:What are the requirements of bearings for sealing?
Bearing seal:Sealing: to prevent dust, water, and other debris from entering the bearings and to prevent lubricant loss.The seals of rolling bearings are generally divided into contact seals, non contact seals and combined seals
Q:Why should the hydraulic cylinder be sealed? Which parts need to be sealed? What are the common sealing rings?
The main purpose of hydraulic cylinder is to push the piston through hydraulic oil to transfer energy to the force body. If the hydraulic cylinder is not sealed, then the two chambers of the tank will be exchanged to form an inner leakage, which will not push the piston to move.Generally in the piston, both ends of the cylinder has a sealing ring (including oil seals and dust).The common sealing rings are O, Y and special sealing rings.
Q:What's the difference between the oil seal and the seal?
The placement of the skeleton has strict requirements, and the standard and specifications of the products are different. Of course, the prices are more expensive than those made in China
Q:Why can't polyurethane seal be used as hydraulic oil with water glycol?
Water glycol lubrication performance is poor, high pressure, sealing components and cylinder block of friction, fever is very serious, so require sealing material to withstand high temperature, usually use fluorine rubber material. Polyurethane is not high temperature, more than 80 degrees when the deformation under pressure, the intensity is low, simply can not use.
Q:Can hydraulic oil be used in the mechanical seal room?
Influence of hydraulic oil on seal and its using methodThe hydraulic oil is used as the working medium of hydraulic system, energy transfer, conversion and control effect, but also has the various parts of the hydraulic system lubrication, corrosion, rust and mechanical seal cooling effect. The seals in the hydraulic system prevent leakage of fluid from the joint surface, maintain pressure, and maintain energy transmission or conversion.
Q:What are the mechanical equipments for producing seals?
For mechanical seal words: lathe, grinding machine, drilling machine, polishing machine, ultrasonic cleaning machine, if the sealing material of their own production, it also need silicon carbide furnace, graphite machine, rubber vulcanizing machine, rubber machine etc..
Q:Seal type of transformer oil tank
2, there may be no reason for the rubber seal installed in the transformer caused by the installation stage, such as excessive compression of the rubber sealing pad lose elasticity, or poorly positioned, local stress is damaged, or the installation of surface roughness caused by local cracks, etc..
Q:What are the basic parameters of the seal on the diagram?
Application: special oil cylinder, pump / valve, machine tool, robot hand, servo mechanism
