In the mechanical world, where machinery and equipment make the earth move and gears rotate, the oil seal is an important component. Oil seals, or shaft seals, are a crucial part of various industrial equipment and applications, ensuring that lubricants don’t escape and contaminants don’t enter. While they may seem simple, their construction, design, and application are anything but. This in-depth guide aims to help you understand the essential role of oil seals, their construction, the various designs available, and key factors to consider when selecting one for your application.
- Another advantage of metal oil seals is their resistance to corrosion and chemical damage. Unlike rubber seals, which can degrade over time when exposed to certain chemicals or fluids, metal oil seals are able to maintain their integrity and performance even in corrosive environments.
- The significance of the small rubber gasket extends beyond its functional purpose. Its standardization allows for easy replacement and maintenance, reducing downtime and repair costs. Moreover, it embodies the principle of simplicity in design—where efficiency does not necessarily require complexity Moreover, it embodies the principle of simplicity in design—where efficiency does not necessarily require complexity

NBR rubber is above all resistant to oils, especially hydraulic oils, lubricants, petrol and other aliphatic hydrocarbons, diluted acids and lyes. Good physical values such as high friction resistance and ruggedness and good temperature resistance (-25 °C up to +120 °C, in part to -40 °C) give this natural rubber a wide range of uses.
Oil seals are protective elements. They prevent the mixing of water and lubricants within a machine, thereby ensuring optimal machine functionality. Also, oil seals help to prevent lubricant leakage at high pressure like when the machine is working at an extremely high rate. Not only that, radial shaft seals stop foreign components from entering a machine. This is because they can contaminate the lubricant and even damage the machine.

WHAT ARE THE TYPES OF OIL SEALS?
Vulcanizates of several fluoroelastomers, listed in Table 14.1, were exposed to a standard 5W-30 engine oil, ASTM Service Fluid 105, for up to 6 weeks at 150°C (302°F).5 The oil was changed weekly, but was not aerated. Retained elongation was measured after exposure for 1, 2, 3, and 6 weeks; data are shown in Fig. 14.3. The results indicate that bisphenol-cured FKM-A500 VDF/HFP copolymer, FKM-B600 VDF/HFP/TFE terpolymer, and peroxide-cured FEPM-7456 TFE/P/VDF terpolymer lost most of their original elongation over the course of the test exposure, indicating considerable additional cross-linking occurred by reaction with amine- and phenol-containing oil additives. The other fluoroelastomers showed better retention of elongation, being much less susceptible to additional crosslinking. Note that FEPM-7456 contains a high level of VDF (about 30%), while FEPM-7506 contains a relatively low VDF level (10–15%) to serve as cure site for bisphenol curing. The other FEPM types contain no VDF.
All are fitted with a spring to preload the sealing lip. All these types are for non-pressurised or low-pressure applications up to 0.5 bar for diameters of a limited size. For diameter of 500 mm or more, the maximum pressure is 0.1 bar. For higher pressures, special types or PTFE lip seals can be used.
