Aspects to consider when selecting oil seals

rubber or polymer

Table 4: JTEKT oil seal type codes and corresponding ISO and JIS standards

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”.

The oil seal turbo, also referred to as the turbocharger oil seal, is a vital component in turbocharged engines. It is designed to contain the oil within the turbocharger, preventing leaks and ensuring the efficient operation of the turbo system. The oil seal turbo plays a key role in maintaining the proper lubrication and cooling of the turbocharger, contributing to the performance and durability of the engine.
