Leather is probably the oldest of the lip materials still in common use, but the move towards mass production methods has seen a massive increase in the development of synthetic rubbers which lend themselves to accurate and repeatable injection and compression moulding. Nitrile (NBR) is still by far the most common elastomer for “normal” use, whilst Viton® (FKM/FPM) is rapidly replacing Polyacrylate (ACM) and Silicone (VMQ) for high-temperature applications. Viton® also has high resistance to abrasion and chemical attack making it a preferred elastomer. Recent developments in the use of PTFE for Rotary shaft seals has caused widespread interest particularly for high-speed shaft rotation or poor lubrication applications.

- In addition to the cost of the spark plugs, it's also important to consider the lifespan of the spark plugs you choose. Some spark plugs may need to be replaced more frequently than others, which can impact the overall cost of maintenance for your vehicle. Investing in long-lasting spark plugs may save you money in the long term by reducing the frequency of replacements.
- Oil seals are typically made from materials such as rubber, silicone, or metal, depending on the specific requirements of the application. The seal is installed in a housing or bore around a rotating shaft to prevent the escape of oil or grease and to keep out contaminants such as dust and dirt.
Shaft Hardness
An overview of the different standard types of oil seals and their main characteristics is shown below.
- But it's not just about performance
- The primary function of the rotavator oil seal is to prevent oil loss. A leak in the seal can lead to a reduction in lubrication, causing increased friction and overheating of the machinery. This not only reduces the rotavator's performance but also shortens its lifespan. Moreover, if contaminants enter the system, they can damage bearings, gears, and other essential components, leading to costly repairs or even complete machine failure Moreover, if contaminants enter the system, they can damage bearings, gears, and other essential components, leading to costly repairs or even complete machine failure

The shaft on which the oil seal is mounted has to be ground to a rough surface finish. The shaft also should be hardened to prevent grooves forming on the shaft when the pressure is exerted by the spring on the seal. The area where the seal is fitted also has to be ground to prevent grooves that tend to wear out the lip of the oil seal faster than normal.
Shaft Surface Finishing
A
Seals are designed to create a tight seal around the shaft by utilising a combination of lip geometry, surface tension, and lubrication. When the shaft rotates, the lip of the oil seal comes into contact with the shaft surface, creating a frictional force that generates heat. This heat helps to soften and conform the elastomeric material of the oil seal to the shape of the shaft, ensuring an effective sealing action.

As shown in Figure 1, sealing devices come in two types: contact and non-contact.
Oil seals are among the major contact type sealing devices.
