Most oil seals are designed to support very low-pressure (8 psi or less) applications. If at all, there will be additional pressure along the way, pressure relief should be put into play. This is why it’s important to know the characteristics of the oil seals you are considering and compare them with your application.
a) The shaft on which the oil seal is to be mounted should be ground with the surface finish or surface roughness between 0.2 to 0.8 Microns. It is best for the shaft to be hardened atleast to 40 – 45 HRc in order to prevent groove formation on the shaft due to the pressure exerted by the spring.
