Stainless steel oil sealWhat are the characteristics?

1. chemical name is polytetrafluoroethylene, it is a mixture of composite materials, with corrosion resistance and self-lubricating properties and many other common plastics do not have. Stainless steel oil seal means the use of PTFE superior chemical and physical properties. The oil seal has good self-lubricating wear resistance and good corrosion resistance even in a low oil environment.

2. stainless steel oil seal can work in high temperature environment, PTFE plastic can maintain stable chemical and physical properties in the environment of -80 degrees to 260 degrees.

In addition to their excellent tribological properties, 3. also have excellent chemical resistance to corrosion. Widely used in medical products and food industry. PTFE and stainless steel material strong acid, strong alkali or strong oxidant and toluene, xylene and other excellent characteristics, with the characteristics of oil-free self-lubrication, but also suitable for high cleanliness of food and medical products processing environment.

4. applicable machinery: screw compressor, vacuum pump, engine, transmission, flour mixer, beverage slicer, cooking machine, robot, medicine grinder, centrifuge, blower, etc. Product medical product processing environment; suitable for models: compressor, vacuum pump, hot oil pump, mixer, cooking machine, robot, medicine grinder, centrifuge, transmission, blower, etc.

Stainless steel oil seals are widely used in automobiles, engine crankshafts, camshafts, differentials, shock absorbers, front and rear wheels, etc. His role is generally to isolate the parts that need lubrication and output parts in the transmission parts to avoid lubricating oil leakage. It is usually used for rotating shafts and is a rotating shaft lip seal. The stainless steel part acts as a reinforcement between the rotating shafts so that the oil seal can maintain shape and tension. According to the different types of skeleton, it can be divided into inner stainless steel oil seal, outer stainless steel oil seal, inner and outer exposed stainless steel oil seal. The stainless steel oil seal is made of nitrile rubber and steel plate, with stable quality and long service life.

Since there is an oil film controlled by the edge of the oil seal between the stainless steel oil seal and the shaft, the oil film has fluid lubrication characteristics. Under the action of the stainless steel oil seal, the rigidity of the oil film just forms a crescent surface at the contact end of the oil film and the air to prevent the leakage of the working medium and realize the sealing of the rotating shaft. The sealing ability of the stainless steel oil seal depends on the thickness of the oil film on the sealing surface. If the thickness is too large, the oil seal will leak. If the thickness is too small, dry friction may occur, causing wear of the oil seal and the shaft; when there is no oil film between the lip and the shaft, It is easy to cause heat and wear. Therefore, it is necessary to apply oil on the sealing ring so that the stainless steel oil seal is perpendicular to the axis line. If it is not vertical, the sealing lip of the oil seal will drain the lubricating oil from the shaft, causing excessive wear of the sealing lip. Ideally, in operation, the lubricant in the casing will slightly seep out and form an oil film on the sealing surface.
