what is the function of oil seal
The hub axle seal's primary function is to keep the axle lubricated. The lubricant, often a type of grease or oil, is crucial for reducing friction between moving parts. Without proper lubrication, the components can suffer from overheating and excessive wear, potentially leading to significant damage and costly repairs. Additionally, the seal prevents water and dirt from entering the axle assembly, which can cause rust and corrosion, further jeopardizing the integrity of the axle.

In the pharmaceutical sector, HPMC serves multiple roles, including functioning as a binder, thickener, and film-forming agent in tablets and capsules. Its use in controlled-release formulations has gained popularity, as it can regulate the release rate of active ingredients. This allows for improved bioavailability and reduced side effects, as medications can be delivered more effectively over extended periods. Furthermore, HPMC's compatibility with a variety of substances makes it a suitable choice for various drug formulations, including those for ophthalmic and topical applications.
