Factors To Consider When Choosing Shaft Seals

By Gwen Lowe


The decision to choose a shaft seal for specific application can be encircled by doubts and dissatisfaction. Considering that a person has to choose from the various shaft seals available that have different specifications, making an informed decision on which to choose can be a great challenge. However, there are various factors, which people should consider to make their selection simpler.

The temperature variance between the shafts and the potential seal should be equal or nearly the same. This is because if you use a seal in an environment where the operating temperature is higher, it would wear out. By choosing a seal whose temperature equals the one for your shafts, you would be sure of improving its lifespan.

Normally, seals are not created with the ability to endure the impacts of pressure. Therefore, exposing them to high pressure can reduce their lifespan and performance. With the improved technology, nowadays some designers are creating custom-made sealing materials to meet certain specifications. Before choosing, it is important to determine if the seal you choose can meet the operating specifications of your shafts.

One other vital factor to consider is the kind of finish. Normally, sealing poorly finished shafts creates room for wear and tear, which also can cause leaks. In addition, you should remember that sealing shafts whose finishing marks and fluid do not move at the same direction when the shaft is rotating can pose the system into various damages. Therefore, before sealing certain surfaces, you should ensure they are conditioned well.

People also need to choose a seal that matches their desires and specifications. A person is required to decide whether to go for leather or synthetic seals. Before you decide to choose any of these two, you need to remember that rubber can resist the impacts of shaft finishes better than synthetic. In addition, rubber generates a self-lubricated sealing with no or little lubrication.

Another vital factor to consider is where the potential seal would be used. Manufacturers use different materials when coating surfaces depending on where they want such coats to be used. The materials used to make the coatings that are used on acidic conditions would have better resistance to acidity than the ones used in corrosive environments. You should know the condition of the potential application before you decide to choose certain coatings.

Shafts do not move at the same speed. This means the eccentricity, run-out and finish on different shafts would vary greatly. In addition, they would also use different types and amounts of lubricants. Before you choose a seal, you need to make sure it can work to meet the specification of such shafts depending on the speed, the type and the amount of lubricant it can consume.

There are various factors, which people should know before purchasing any product. These are; the design of the item, its quality and its performance. As you choose a seal shaft, it is also important to consider these factors. This is because by knowing these factors, you would be able to make an informed decision on which to choose depending on its quality, performance and design.
