1) Oil seals for cars
Various machines have different components that, when combined, work together as a whole. The equipment will not last forever and will eventually deteriorate through use. The use of mechanical lubrication protects these machines from deterioration while maintaining their designed function.
However, using the wrong type or not applying sufficient lubrication can lead to machine damage, equipment failure, and leaks. Therefore it is important to choose the correct lubricant for your machine.Oil seals are widely used as sealing devices for machines.
JTEKT's oil seals are described in our catalog, Oil Seals & O-Rings.
However, the catalog uses a large number of technical terms and is very long, so many people seem to have trouble handling it.
Therefore, this series of columns will summarize the following in order:
• The structure, functions, and types of oil seals
• How to select the right oil seal
• Handling of seals, and causes and countermeasures for oil seal failureRequirements of the shaft
Even more important than a correct interference fit of the Oil Seal is a perfectly smooth shaft in the region of the seal, particularly if shaft surface speed is high and the medium to be sealed is under a certain amount of excess pressure. The surface roughness of the shaft depends on the average profile depth Ra of the tool marks caused by the machining process. Oil Seals made of PTFE require, independent of the surface speed, a surface roughness of between 0,1 to 0,2 mm, because PTFE has less wear resistance than rubber seals. For normal circumstances, the shaft in the region of the seal must have a surface roughness of approximately: To summarize, the surface of the shaft in the region of the seal should not have noticeable machining marks. For pivoting shafts and other difficult or critical sealing applications, it is recommended that Oil Seals with a helical groove hydrodynamic pattern, which has a pumping effect, be used. When grinding and polishing, an axial movement of the grindstone along the shaft must be avoided in order to prevent machine lay.The oil pan seal, also known as the oil pan gasket, is a critical component in an automobile's engine system. It is responsible for sealing the oil pan to the engine block, preventing oil leaks and ensuring the proper lubrication of the engine. The seal oil pan plays a crucial role in maintaining the oil pressure and preventing the loss of lubricating oil, which is essential for the smooth operation and longevity of the engine.

- In conclusion, the double oil seal is a testament to the importance of thoughtful engineering in ensuring the efficient and safe functioning of complex mechanical systems. Its dual-layered protection is a testament to the relentless pursuit of reliability and durability in industrial applications. As technology continues to evolve, so too will the design and effectiveness of these crucial sealing mechanisms, further cementing their role in a wide array of industries.

Type ‘C’ oil seal has an additional cup inserted into the outer cup of ‘B’ type. The supplementary metal inner ring provides a superior stiffness. This type is recommended for use in heavy polluted environments. As the static sealing between housing and metallic shell is limited, low viscosity media can “creep”.
