One of the key features of the 75x100x10 oil seal is its durability and resistance to wear and tear. Made from high-quality materials such as rubber, metal, and fabric, this oil seal can withstand high temperatures, pressure, and friction without losing its sealing capabilities. This makes it a long-lasting solution for machinery that operates in demanding environments.

Tighten all fixings in sequence to the correct torque (consult a service manual or dealer if you are uncertain of the torque).
The numbers 30-50-10 indicate the dimensions of the oil seal, specifically its inner diameter, outer diameter, and height. This measurement ensures that the oil seal fits perfectly into the designated space and effectively seals off any potential leaks.
The sealing element, also known as the sealing lip, forms the interior of the oil seal. Various materials can make up the lip depending on the application’s specific needs. Below are some commonly used materials:
From this kind of standard immersion testing, one would expect that bisphenol-cured VDF/HFP/TFE fluoroelastomers would not give good service life as oil seals. Similar tests with other elastomers, such as HNBR, silicone, and acrylic rubbers, show less loss of elongation. However, it is found that, in actual service, FKM shaft seals6 have much longer service life than seals of the other elastomers. In a Japanese study of FKM lip seals, rear crankshaft seals from high-mileage automobiles (70,000–280,000 mi ie, 110,000–450,000 km) were collected and examined. No serious oil leakage was found when the seals were removed from the engines. Some deposits were found around the seal lip and on the garter spring holding the lip against the shaft. No surface cracks were found on the seal lip, and only minor crazing on the crankcase side of the flexure portion of the seal in some samples. The seal compositions were not noted, but most were probably VDF/HFP/TFE elastomers with 68–69% fluorine content.
