(if the housing bore has a shoulder)
Both sealing types are popularly used in different mechanical engineering applications. How are they different? The article explains the fundamental working mechanism of both categories of seals.
Choosing Quality Oil Seals for Wheel Hubs and Steering Mechanisms
Oil seals can also be known as rotary shafts seals, shaft seals, lip seals, elastomeric seals, and more.
It is quite common for a groove to develop at the sealing lip at some point due to long-term use. As a result, the new oil seal no longer fits and seals properly. It is not strictly necessary to replace or repair the entire shaft. Take a closer look at the dimensions first. It may be possible to fit with a slightly narrower or wider oil seal next to the groove. Alternatively, using the Speedi-Sleeve repair kit, repair the running surface under the seal.

motor oil seal. Signs that a motor oil seal may be failing include oil leaks around the engine, low oil levels, and unusual engine noises.
Rubber type
Oil seals require sufficient time to solidify and cure. Premature use of equipment with newly installed oil seals can compromise the integrity of the oil seal and may damage your machine. Refer to the supplied instructions for the time frame allocated for the seal to cure.
