Comprehensive Guide to Oil Seal Applications and Product Types

Understanding Oil Seal Selection and Applications

#

Selecting the right oil seal for a specific application is crucial and depends on the operating conditions the seal will encounter. This guide provides detailed information on the types of seals offered by LYO and their intended uses, helping you make informed decisions for your sealing needs.

High Quality Product Groups

#

Group A: Shaft Seals

#

One of the most widely used designs, Group A shaft seals are press-fitted into the housing bore. The sealing is achieved through the sliding surface contact between the seal lip and the shaft. A close-coiled helical spring is incorporated to maintain effective sealing.

Group B: External Seals

#

External seals are press-fitted onto a shaft, with the lip and housing bore providing sliding surface contact. These are used in specific scenarios where traditional shaft seals are difficult to install. Pitch-coiled springs are utilized in this design.
