Oil seals serve an important function in preventing lubricant leaks by closing in the spaces between the parts of the rotary shaft equipment. They also prevent dirt, dust, and other contaminants from clogging up the unit. Having them properly installed enables engines, pumps, and pipes to operate more efficiently.

Prepare the shaft and prevent damage

The dimensions of the 25x47x7 oil seal refer to its inner diameter, outer diameter, and thickness, respectively. These measurements are important in ensuring a proper fit for the seal in the machine or engine it is intended for. By providing a secure seal between moving parts, the oil seal helps to maintain proper lubrication in the machine and prevent the loss of oil.

Polyacrylate 
Better heat, oil and chemical resistance than NBR 
It is recommended for use in oil which contains load bearing additives such as EP gear oils

Oil seals come in various shapes to fit the machine or substance for sealing.
For this reason, when designing a machine, it is important to select the oil seal that is right for that machine.
Next time, we will explain the key points to consider when selecting your oil seal.

In addition to its excellent temperature resistance, it is also resistant to ozone, light, and weather conditions. Silicone can be typically found in the food and medical industry as well as in hydraulics and pneumatics. It is often the preferred material for o-rings, moulded parts and flat seals but is also commonly used for electric insulators due to the material’s translucency and flexibility.
