What are oil seals?
Oil seals, also known as rotary shaft seals, are a type of gasket used to prevent lubricant leakage and contamination in rotating machinery by creating a barrier between the moving and stationary parts.

The basic principle of an oil seal is fairly straightforward. It is installed adjacent to the bearing, with the flexible lip against the rotating shaft and the casing pressed into the housing to hold the seal in place. It’s important that the sealing lip is lubricated to prevent it from overheating as a result of any generated friction. It’s also crucial to understand which type of seal is appropriate for your particular machinery. Before selecting your seal, consider the environment, temperature, pressure and shaft speed of your machine, as well as the type of medium the seal will come into contact with during operation. These considerations will all determine the size, colour, and type of lip material or sealing element to choose, and whether it can be sealed in or sealed out.
Whether the seal is a standard product or a custom solution, our engineers ensure that the seal is specified for your application.
The reasons for the birth of this new generation of seals is that integrated oil seals reduce the manufacturing time of series production engines. Therefore, significant time savings are achievable when replacing the radial crankshaft seals.
Fitting an oil seal
Smear gasket sealant on the mating faces of the pump and the engine. Refit the pump and gasket or gaskets and tighten the fixings.
When selecting spark plugs for vehicles, it is essential to consider factors such as compatibility, heat range, electrode design, and material composition. High-quality spark plugs, including iridium spark plugs, are designed to withstand the demanding conditions of automotive operation, providing reliable ignition and combustion. Choosing reputable suppliers and manufacturers known for producing high-quality spark plugs is crucial to ensure the reliability and longevity of these critical components in the vehicle's ignition system.
