Oil seals are an essential component of many industrial machines and equipment. They play a crucial role in preventing oil leaks, protecting bearings and other crucial parts from contamination, and ensuring the overall smooth operation of the machinery. One popular and widely-used size of oil seal is the 75x100x10 model.
PTFE, which is used in the well-known brand Teflon®, is less commonly used, but it is the preferred material for specific rotating seals in the chemical, food and pharmaceutical industries. This material is notable for having a very low frictional resistance and the best chemical resistance. It can also withstand a very wide range of temperatures in these types of seals; -80 ˚C to 200 ˚C. The shafts on which oil seals with PTFE lips are used require a harder and finer finish. Something like an axle sleeve can also be used to meet this requirement.
EPDM oil seals are less common. They are used in solvent, hot water and steam applications, EPDM resists low temperatures down to -50 °C and UV radiation well. Some types of EPDM are also suitable for higher temperatures up to +150 °C. EPDM oil seals are usually available upon request.

In the realm of automotive maintenance, the health of spark plug wires is often underestimated. These seemingly innocuous components play a pivotal role in the efficient running of an internal combustion engine. Testing spark plug wires may not be as glamorous as tuning up the engine or replacing high-performance parts, but it's a critical aspect of ensuring optimal performance and longevity.Motor oils typically include a few additives which can make up between 5% and 30% of the oil. These additives help enhance the performance of the oil. Motor oils can include the following additives:
There are several common types of oil seal dimensions, each serving a specific purpose and application.The sealing effect is achieved by manufacturing a smaller inside diameter than the required shaft size, which preloads the sealing lip. A garter spring is often used to ensure a constant force on the shaft.
