- Oil seals are integral components in the operation of machinery, serving as a barrier between the lubricating oil and the external environment. Their primary function is to prevent the leakage of oil from the system while allowing the rotation of the shaft. The performance of these seals is critical to the overall efficiency and longevity of the machinery.
- It offers a temperature range from -85 degrees Fahrenheit to 400 degrees Fahrenheit

What is an oil seal and how does it work?
Oil or other seals can be used for grease and oil seals. A flexible lip, radial lip, or rotating shaft seal are different names for an oil seal. Single lip, double lip, triple lip, and four or more lips are frequent configurations. Double dust lip seal A seal with a garter spring design is the Double Dust Lip (DDL) seal. It has two dust lips, as the name would imply, plus a fluid lip with a garter spring to keep the lip firmly attached to the wear ring. Given the ongoing evolution of bearing seal designs, this seal would be considered a starting seal. For more than 50 years, this design has been the workhorse of the freight business; it still is in some regions. NBC Brenco Bearing Seal performs the fundamental task of keeping contaminants and grease out. Because of the garter spring, this seal would add the most torque and temperature to the bearing. Efficiency plus bearing seals Due to eliminating the fluid lip using poly inserts and rotors, the Efficiency Plus (EP) seal has a reduced torque value of fewer than 15 in-lbs. Although it features a triple dust lip rather than a double dust lip, the dust lip is still a molded component of the design. A labyrinth-like insert and rotor interlock each other to replace the fluid lip. NBC Brenco labyrinth provides excellent grease while lowering the torque required to rotate the seal. Other types of oil seal and grease seals include:
Installing and replacing the 75x100x10 oil seal is a straightforward process that can be done by maintenance personnel with basic mechanical skills. It's important to ensure that the shaft and housing where the oil seal will be placed are clean and free of any debris or damage. Proper lubrication of the shaft is also crucial to prevent premature wear of the oil seal.
Typically used in hydraulic high-stress applications where compounds under high pressure are exposed to wear, the benefits of polyurethane seals include:
