Oil Seals without Spring
The allowable total eccentricity is the maximum total eccentricity at which the sealing edge can accommodate shaft rotation and retain adequate sealing performance. The oil seal's allowable total eccentricity is affected by the design of the oil seal, the accuracy of the shaft, and the operating conditions.
Different types of rotary shaft seals are available in the market, including radial lip, axial lip, and mechanical face seals.
In choosing the right oil seal type for your application, it is essential to assess factors such as speed, temperature range, pressure levels, chemical compatibility, shaft material, and installation space limitations. By considering these factors carefully, you can ensure that you select an oil seal that will provide optimal performance and longevity in your specific application.
