Most ERIKS oil seals, such as the types M, MST, R and RST, are made of NBR as standard.
This refers to the component of the oil seal that makes contact with the shaft.
It is wedge-shaped to be pressed against the shaft surface and makes contact with the shaft to ensure sufficient sealing performance and suitability for operation at high peripheral speed.4) Allowable total eccentricity
- 5. Set the spark plug gap Use the spark plug gap tool to set the correct gap between the center electrode and ground electrode of the plug.
Oil seals close off the space between stationary and moving components in the mechanical equipment. It saves the lubricant from escaping through the equipment and ensures smooth operation of the machine.

Operating conditions such as the engine’s temperature, position, size, pressure and shaft speed largely determine which individual oil seal composition is most suitable for every individual application.
With a helper holding the engine steady, remove the wedge supports, lower the engine and reconnect the mountings loosely.
When choosing seal materials, it is critical to evaluate the environment and application. Common seal materials include:
