- Furthermore, the oil seal 12 22 5 also helps to maintain the lubrication system of the machinery, ensuring that the moving parts are properly lubricated. This is essential for reducing friction and wear on the components, ultimately improving the efficiency and performance of the equipment.

Type code- Overall, skeleton oil sealing is a fundamental component in machinery and equipment that relies on lubrication for smooth operation. By preventing leaks and keeping out contaminants, oil seals help to extend the lifespan of machinery and reduce the risk of costly repairs. It is essential to choose high-quality oil seals and ensure they are properly installed and maintained to maximize their efficiency and protect the longevity of your equipment.

The hardness of the shaft determines how long the seal will last. A shaft should have a Rockwell hardness of 30 or more. It prevents the seal from getting damaged when it’s exposed to abrasive agents.



When deciding on the best type of seal for a particular application, it is best to consider all aspects of the environment and its purpose. If the application requires a spring- loaded seal, that does not eliminate either the rotary shaft seal or the mechanical seal. If the equipment is operating in extreme temperatures, including situations where the rapid movement of the equipment creates extreme heat, a mechanical seal will hold up better than an oil seal.
Oil seals come in a wide range of types, and they also have various sizes.
When selecting the right oil seal for your machine from among these many varied types of oil seals, the following two criteria are very important.


It is generally used in the union of two lubricated parts, so that it hermetically seals both sides. Therefore, it guarantees the proper engine operation and helps to maintain the vehicle’s distribution system in better condition.
In recent research, MWCNTs and carbon black were mixed with the butadiene/natural rubber to form a hybrid composite which gives very strong filler links by partial replacement of carbon black based on the m1:m2:X (m1—MWCNT; m2—reduction amount of carbon black; X-varies from 1 to 6) [40,64]. An internal blending mixer and two-roll milling were used to formulate the composites. The synergistic effect plays a major role in improving the abrasion resistance property due to the partial replacement of carbon black by adding MWCNTs in different ratios. The optimal ratio value of MWCNTs is 5 (parts per hundred of rubber) and 27.5 (parts per hundred of rubber) for carbon black with better resistant to abrasion compared to the matrix material [64]. The vulcanized hybrid composite material reinforced with MWCNT/carbon black at the ratio of 1:1 shows better mechanical properties, curing characteristics, and thermal conductivity. This shows a better tyre thread with an improved endurance life, less curing time, and improved thermal conductivity [42,64]. Fig. 4.4 shows the SEM and TEM images of uncured and cured rubber and Figs. 4.5 and 4.6 show the application of rubber nanocomposites in a tyre application.
