Describe difference between mechanical seal and oil seal – Whether it is a mechanical seal or oil seal, it prevents the fluid seeping the liquid to other parts of the machine, or it keeps the rotating parts lubricated.
- In the intricate world of mechanical engineering, oil seals play an indispensable role in ensuring the efficient and safe operation of various machines. The 40x52x7 oil seal, in particular, stands as a testament to the precision and importance of these seemingly small yet vital components.

Rubber oil seals have to perform in extreme conditions. Therefore, we accommodate all relevant conditions (mechanical and thermo-chemical phase) to maintain the integrity of the rubber oil seal in these circumstances.
The auto head gasket, also known as the cylinder head gasket, is a critical component in the engine that seals the cylinder head to the engine block. This gasket plays a pivotal role in maintaining the combustion chamber's integrity, preventing the leakage of coolant, oil, or combustion gases. A properly functioning auto head gasket is essential for ensuring optimal engine performance, preventing overheating, and maintaining the overall efficiency of the engine.

Oil seals are available in an immense range of sizes, for shafts from a few millimetres to several metres. Once the shaft diameter, groove diameter (housing diameter) and groove width are known, selecting an appropriate oil seal is a simple task. An oil seal or its product description is usually associated with three dimensions, for example 6x15x4. These refer to the sizes of the hardware for which the oil seal is designed. In this example, this oil seal is suitable for: 6-mm shaft diameter x 15-mm groove diameter x 4-mm minimum groove width.
