Rotary shaft seals are used to seal the space between stationary and rotating components. They prevent leaks and keep contaminants from entering your system. There are different types of shaft seals for a wide range of applications. With this video, I want to help you make the right choice.
This has the added benefit of extending the life of the shaft seal.
The shaft seals are made according to DIN 3760. This makes it possible to interchange shaft seals between brands.
A shaft seal is typically identified by 1 or 2 letters. The first letter identifies the type of shaft seal and construction. There are Types A, B, or C. If there are additional variations to the standard shaft seal, there is another letter.
Type A has a rubber exterior and is the most standard type. The advantage of rubber is that it doesn't rust, can seal a slightly uneven housing much better, and when used at high temperatures the rubber will expand quickly making the shaft seal fit extra tight.
Type B is the variant with a metal exterior. A metal shaft seal is generally more cost-effective. If you choose a metal shaft seal, note that the shaft seal, housing, and shaft must have the same thermal expansion coefficient. Too great of a difference in expansion coefficient can cause the system to leak with temperature changes.
Type C is similar to type B but has an additional reinforcing cap. This type is often used for large diameter applications and heavy-duty operating conditions.
