Some Important Things To Know Before Picking Shaft Seals

By Gwen Lowe


It is usually confusing and relatively frustrating to determine the best seal that can meet the operating specifications of your shaft. This is because there are many types available that should be used for different purposes and in different ways. As such, for anyone to choose the best shaft seals that can meet the functioning standards of their shafts, they need to know various things.

One of the main factors to consider when choosing a seal is the variation in temperature between the shaft and the seal. Naturally, seals tend to wear out if exposed to applications where the operating temperature exceeds the temperature of the seal. Therefore, in order to improve the lifespan of your shafts, it is advisable to choose a seal, which has the same temperature range as your device.

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 should also decide on which seal to choose. Normally, coats can be obtained from either leather or synthetic materials. The rubber-made coats usually have better resistance to corrosive conditions as compared to the ones made of synthetic materials. Additionally, rubber-made coats usually generate a self-lubricated coat whether lubricated or not.

In order to select the most appropriate coat for your special application, it is also important to know whether it can meet the operating specifications of such shafts. In most cases, designers create certain coats depending on the conditions of the environments on which they would be used. It is important to know whether the potential application is corrosive or not as the coats made for use in corrosive conditions would have better resistance than the ones that are not.

Different shafts move at different speeds. When choosing shafts, you should determine their eccentricity, run-out and the finish. You should also know the kind and the amount of lubrication such shafts are designed to use as this would determine the speed at which such shafts can move to help you choose the best seal.

People consider many things whenever choosing and shopping for certain products. These range from the quality, performance and the design of such products. These are also some of the main factors to put into consideration when choosing a seal for your shafts. You should make sure you know them before making your decision, as this would help you get the best products.
