  • Once you have selected the most suitable seal available, considering the environment, temperature, shaft speed, pressure, lubrication availability, as well as the size, of course, the seal should be stored adequately and then fitted properly. Here are a few suggestions that could help:-

  • Inspection of Seal and Bore: Before installation, clean the seal, shaft, and bore. Then inspect each one for defects, abrasions, or residues. Use visual inspection and tactile feedback to ensure no imperfections are present. Undetected flaws or debris can lead to leaks or blowouts under pressure.

  • What Are Oil Seals?

  • Small oil seals are designed to withstand the test of time and the vagaries of their environment. Crafted from materials such as rubber, silicone, or synthetic compounds, these seals are engineered to be resilient against temperature fluctuations, chemical exposure, and physical stress. Their design is meticulous, featuring lips that hug the shaft tightly, creating a barrier that is both flexible and durable. This flexibility allows the seal to adapt to minor movements and vibrations without compromising its integrity, thus reducing the potential for leaks.

  • Power steering oil seals are integral to the functionality of the vehicle's power steering system. These seals are responsible for containing the hydraulic fluid within the power steering mechanism, preventing leaks and maintaining the smooth operation of the steering components. Power steering oil seals contribute to the proper functioning and longevity of the steering system, ensuring precise and responsive vehicle control.

  • The temperature range of nitrile is −35° to 120 °C (−30° to 250 °F). Due to this wide range, NBR seals can be used for gas oil, silicone oil, animal/vegetable oils and fat, hydraulic liquid as well as hot and cold water. In addition, NBR is oil resistant and has an excellent abrasion resistance, so for any application that demands shock absorbers, NBR is a perfect choice to go with.

  • In addition to their durability and reliability, metal cased oil seals are relatively easy to install and maintain. They are designed to fit securely into the housing or assembly of the equipment, ensuring a hassle-free installation process. Once in place, these seals require minimal maintenance and can be easily replaced when necessary, reducing downtime and maintenance costs.

  • When you start the actual installation make sure that the oil seal is always facing the right direction. So, not facing outwards, but always with the spring facing the side of the medium to be sealed. The oil seal must then be pressed into the bore. Use appropriate tools, such as a bearing fitting tool set, to ensure that this is done evenly. The oil seal must never be forcefully hammered into the bore.
