- Despite their compact size, oil seal rubber parts have a significant impact on overall system performance and safety. Regular inspection and timely replacement of worn-out seals can prevent major machinery breakdowns, saving substantial costs associated with repair and downtime.
- Oil seals serve as a barrier, preventing oil from escaping the confines of the machinery while also stopping contaminants from entering
- Applications of NBR Oil Seals
- The inclusion of 7% steel, often in the form of a metallic insert or spring, further fortifies the oil seal's performance
Before installing the oil seal, it is important to lubricate it to reduce friction and prevent damage during installation. A silicone-based lubricant is recommended for most applications. If the oil seal is to be installed in a high-temperature or high-pressure environment, a more specialized lubricant may be required.

metric oil seals. Proper installation is crucial to ensure a secure seal and efficient operation of the equipment. Regular maintenance and inspection of the seals are also important to identify any signs of wear or damage that may compromise their effectiveness.

The allowable total eccentricity is the maximum total eccentricity at which the sealing edge can accommodate shaft rotation and retain adequate sealing performance. The oil seal's allowable total eccentricity is affected by the design of the oil seal, the accuracy of the shaft, and the operating conditions.
