Conventional oil seals are the traditional seals, which can be recognised by a spring on the inside. These oil seals are made of a metal housing that contains a rubber seal. This part is often made of elastomer and comes into contact with the surface of the rotating shaft.
By first finding out the dimensions of the inner and outer diameters and the height of the bore, you have all the data for the correct size of the oil seal. Of course, the oil seal must also be able to withstand the pressure, temperature and medium it is exposed to within the seal during the manufacturing process. You can read more about this in our oil seal selection guide.
In the world of industrial sealing, neoprene rubber gaskets have emerged as a popular choice among manufacturers and engineers alike. These gaskets are made from a synthetic rubber material known as neoprene, which is renowned for its excellent resistance to oils, solvents, and heat. This makes neoprene rubber gaskets an ideal solution for a wide range of sealing applications in various industries. Another significant advantage of these gaskets is their versatility. They can be made from a wide range of materials, including rubber, silicone, PTFE, and neoprene, among others. Each material offers unique properties such as、、,。
Shaft Speed - Considering the speed that the shaft will be moving, the runout, the housing bore and the type of oil being sealed is vital to making sure you select an oil seal that will not suffer from abrasions or spiralling.
Many – too numerous to list, covering a vast range of designs, sizes, and materials suitable for a never-ending range of applications. Some designs conform to International Standards such as BS1399 and DIN 3760 for metric sizes and seal types, but the majority have been manufactured to suit particular applications – hence the enormous selection available. This blog is intended to assist in this selection and will consider seal type, materials, and sizes.
The Oil Seal 20/34/7 is a high-performance and durable seal that offers numerous benefits for various applications. Its ability to withstand high pressures and temperatures, as well as its excellent resistance to wear and tear, make it an ideal choice for use in harsh operating conditions. Whether you're working with heavy-duty machinery or need a reliable seal for your engine, the Oil Seal 20/34/7 is sure to meet your needs.The rubber material used in the oil seal should be selected based on the operational temperature and substance to be sealed.
Table 5 lists the major rubber materials along with their operational temperature ranges.
Note that it is necessary to check the compatibility with fluids.
<N.B.>
Extreme pressure additives are compounds added to the lubricant. They are activated by heat and chemically react against rubber, which deteriorates rubber properties. For this reason, it is necessary to check for compatibility with rubber materials.
