Most oil seals are designed to support very low-pressure (8 psi or less) applications. If at all, there will be additional pressure along the way, pressure relief should be put into play. This is why it’s important to know the characteristics of the oil seals you are considering and compare them with your application.

Oil seal for higher pressures

Oil seals made of HNBR are characterised by excellent properties that include high resistance to mineral oils with additives, low steam and gas permeability, good cold flexibility down to -30 °C depending on type, good ozone resistance and friction resistance. HNBR seals withstand heat up to 150°C.
Oil seals come in a range of sizes ranging from 0 cm to 33 cm, and choosing the right size is critical to performance. The size of an oil seal is determined by the following dimensions:

Oil seals operate by creating a tight barrier between two moving or stationary parts, such as a shaft and housing, to prevent oil from escaping and contaminants from entering the system. This is essential for maintaining the efficiency and performance of the machinery, as well as preventing potential safety hazards.
1) Common seal types and their features
In conclusion, wheel hub oil seals and steering oil seals are essential components in automotive systems, contributing to the efficiency, safety, and reliability of the vehicle. Understanding the significance of these seals and their proper maintenance is crucial for optimizing the performance and longevity of the wheel hubs and steering mechanisms.
If there are curved seals, fit these to the engine. Smear sealant on the seal groove, stick the seal in place, and apply a blob of sealant to each end of the seal where it joins the gasket.
