Shaft diameter tolerance - Installation and maintenance of high pressure oil seals require precision and expertise. Incorrect installation can lead to premature failure, while regular inspection and timely replacement are necessary to ensure continued performance and prevent unexpected downtime.

Most oil seals are designed to support very low-pressure (8 psi or less) applications. If at all, there will be additional pressure along the way, pressure relief should be put into play. This is why it’s important to know the characteristics of the oil seals you are considering and compare them with your application.

Cassette seals are designed to maximise grease or oil retention and protection against liquid or solid contaminants. These seals are provided with their own bushings in which dirt is kept out and oil/grease kept in by a multi-lip seal.



rotary shaft oil seal. It is important to choose a high-quality seal that is compatible with the requirements of the system to ensure optimal performance and longevity.
Regular maintenance and inspection of shaft oil seals are essential to ensure their proper functioning and prevent costly downtime and repairs. Signs of a worn or damaged seal include oil leaks, increased noise or vibration, and decreased efficiency. If any of these symptoms are detected, it is important to replace the seal promptly to avoid further damage to the machinery.
