- When selecting an oil seal for a specific application, factors such as operating temperature, pressure, speed, and the type of fluid being sealed must be considered. The oil seal 40x60x10, with its versatile dimensions and robust construction, is often a go-to choice for engineers in industries ranging from automotive to aerospace, manufacturing to mining.
Many – too numerous to list, covering a vast range of designs, sizes, and materials suitable for a never-ending range of applications. Some designs conform to International Standards such as BS1399 and DIN 3760 for metric sizes and seal types, but the majority have been manufactured to suit particular applications – hence the enormous selection available. This blog is intended to assist in this selection and will consider seal type, materials, and sizes.
- Silicone Oil Seals – Are designed to specifically to absorb excess lubricants and less the friction and wear. They offer high thermal resistance and a large temperature range. However, they don’t handle abrasions and oxidized oils well.
- Visual inspection is the simplest method to check the condition of the gasket. Look for any signs of wear, tear, or discoloration. Listen for any unusual noises or vibrations that may indicate a problem with the gasket.
Nitrile Butadiene Rubber (NBR, nitrile)
Similar to the housing surface stop technique, this method uses a stop at the machined housing face to set the seal depth. It is typically used in housings with flat outer surfaces. Verifying the placement through visual inspection or with a feeler gauge ensures placement accuracy.
Properly installed, an oil seal will help keep machinery in perfect working order. Its primary functions include retaining or separating fluids, maintaining a bearing’s lubricity, preventing seal leakage, and preventing the entry of foreign contaminants. Other benefits of Emerson Bearing’s oil seals include:
In addition to preventing oil leakage, the piston oil seal also helps to reduce friction between the piston and the cylinder wall. This is important for maximizing engine efficiency and prolonging the life of the engine components. By reducing friction, the seal helps to improve fuel economy and reduce wear and tear on the engine.
