The most common oil seals are the ERIKS types R, RST, M and MST, which correspond respectively to types A, AS, B and BS according to DIN 3760/ISO 6194.
Take extra care with a light alloy block or head. It is vital to avoid scratching the machined surface.
- .
The maximum allowable shaft speed is a function of the shaft finish, runout, housing bore and shaft concentricity, type of fluid being sealed and the type of oil seal material.
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.

Polyacrylate oil seals are a perfect compromise between quality and cost. They perform well with high temperatures and chemicals, but not as well as Viton oil seals. Polyacrylate has a temperature range of -25 degrees Fahrenheit to 300 degrees Fahrenheit. Due to their outstanding resistance to hot oil and oxidation, they are commonly used in automobile transmissions and hoses; however, they are also used for shaft seals, gaskets, and o-rings.

aircraft spark plug. Over time, spark plugs can become fouled with carbon deposits, oil residue, or other contaminants that can affect their ability to generate a spark. It is essential to clean or replace spark plugs as needed to prevent these issues and maintain optimal engine performance.
In general, oil seals should be selected in the order of priority indicated in Table 1.
