Product Description:

1.Description of Oil Seal:

the Oil seals, O rings, hydraulic seal rings, flange gaskets, wipers, dampers, washer, rubber coupling spiders, rubber sheets, rubber rods, rubber hoses, rubber tube, rubber strip, rubber sleeves, rubber rollers, rubber ball, rubber wheels, rubber stopper, speed bumps, conveyor belt, timing belt, car mat, mining products, etc.

Now we can supply the best high pressure oil seals 


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.

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:The seal of the front end of the cylinder and the cylinder, "O" ring, why has it been serrated for some time?,
It should be considered that the gap between the two mounting surfaces of the 0 type ring is too large.It is recommended to reduce the fit clearance or increase the retaining ring.
Q:What are the differences between polyurethane TPU and CPU in cylinder seals?
TPU thermoplastic polyurethane elastomer (referred to as TPU)Is a new type of polymeric material between rubber and plastic, in practical application, much as rubber replacement products, also has excellent abrasion resistance and CPU (elastic body most), at room temperature into a solid, heated or solution to make it into a liquid, processing after forming, to become solid polyurethane materials. TPU is one of the most widely used and the largest production of polyurethane elastomer, such as sports equipment: skate wheel, shoe buckle, Internet, accessories, snow boots industrial parts: seal, steam pipe, pipe fittings, accessories (dust damping analysis, industrial wheel, conveyor belt material: air pressure pipe, water pipe medical tube, wire and cable, and a watchband, film, shoe soles, shoe accessories: sheet, cushion, accessories, leather, labels and so on, a day
Q:How should the piston rings for piston wear be chosen? What is the national standard?
Cylinder piston due to long-term reciprocating motion, reciprocating piston seals should be used to require wear-resistant, oil corrosion resistance, hardness is best at about 85 degrees.The choice of sealing ring material is of great importance to its sealing performance and service life. The performance of the material directly affects the performance of the sealing ring.
Q:What is the life span of all kinds of rubber seals?
Your question is a false proposition, the rubber seal life is related to material and working conditions, rubber is a lot of weight, there are fluorine rubber, silicone rubber and so on,
Q:What are the equipment needed to produce the sealing ring?
These two are completely different materials, the rubber ring is generally rubber, PTFE is plastic, the production process is not the same. Not familiar with, or first learn more professional knowledge!
Q:How long will it take for the seal to age naturally after the seal has been installed on the cylinder?
This is a lot of factors, first look at what brand of sealing ring! Good brand in a certain environment, aging slow!
Q:What tools are needed to replace the water seal for the air conditioning pump? What's the name?
Here I introduce the replacement of mechanical seals technical points:Mechanical seal principleThe seal is defined by at least a pair of end faces perpendicular to the axis of rotation of the fluid pressure and the elasticity of compensation organizations (or force) the role of the device and auxiliary seal with maintaining relative sliding postmerger and constitutes to prevent fluid leakage. The main parts of mechanical seals are as follows: A. main seals: moving ring and stationary ring. B. auxiliary seals: seals. C. press: spring.
Q:Reasons affecting the tightness of cylinder
Mainly machining accuracy, the sealing pad between the cylinders also plays a big role. There is the problem of design, basically mature products will not appear airtight problems
Q:What are the categories of commonly used hydraulic seals?
The most common are the O ring, the shaft seal, the lip ring, the collar ring (the O-ring), the combination seal, etc. all other seals are these sealed deformations.
