By first finding out the dimensions of the inner and outer diameters and the height of the bore, you have all the data for the correct size of the oil seal. Of course, the oil seal must also be able to withstand the pressure, temperature and medium it is exposed to within the seal during the manufacturing process. You can read more about this in our oil seal selection guide.

In conclusion, TC oil sealing is an essential component in various mechanical systems that helps to prevent leaks, reduce friction, and prolong the lifespan of machinery. By providing a secure barrier against oil and fluid leakage, TC oil seals play a critical role in maintaining the efficiency and performance of machinery in a wide range of applications. Investing in high-quality TC oil seals and ensuring their proper installation and maintenance will ultimately result in cost savings and improved operational efficiency.Figure 5 explains the JTEKT seal numbering system.
Seal numbers consist of
(1) the seal type code,
(2) the spring code,
(3) the lip type code,
(4) the dimensional numbers, and
(5) the special type code,
and Table 6 shows examples of each of these codes/numbers.
Seals are essential to protecting the bearings of any rotating shaft assembly -They prevent contaminants such as dirt, dust and water, while also preserving the system’s lubricant.
Please see the following for the types of sealing devices for bearings.
