Shaft seals, or oil seals, are used between two rotating or non-rotating components, to protect the machinery
from contamination, and to keep lubrication properly contained. Shaft seals are comprised of a cylindrical outer covering, usually made of steel or elastomer, to seal against the housing bore and facilitate installation, and a sealing lip made of elastomer or thermoplastic, providing dynamic and static sealing against the shaft. Shaft seals are a vital component of bearing machinery, and are therefore widely standardized, allowing for simple seal replacement or matching. There are a multitude of seal types and materials for different applications, such as general purpose clipper, split clipper, rotary sealing, high misalignment or high pressure rotary shaft clipper, shallow cavity general purpose, heavy duty spring loaded or clipper, reduced friction, split pillow block
rotary shaft seal, as well as light duty and low speed seals. Some seals feature an auxiliary lip to protect the primary sealing lip, increasing operating life and reducing maintenance requirements. Additionally, the type of lubrication
will impact the friction and performance of the shaft seal. If you’re unsure of which seal type is right for your application, ask our experts at MRO Supply. We carry a wide variety of shaft seals of different sizes, designs, materials, and manufacturers to suit any application.
