Rotary Shaft Seal Buying Guide

Virtually everyone wants to protect their machinery from long-term and immediate damage. Seals, which are also referred to as grease seals or rotary shaft seals are an excellent way of sealing the gaps between mechanical equipment. However, it takes careful considerations to find the right oil seal for stationary or moving equipment. Here are a few factors to consider when selecting a seal.

Lubricant Amount

Seals often tend to work well when they’re lubricated. Seals in some machines are likely to remain dry. However, PTFE or leather seals come in handy for such cases, as they can operate with both high level and less lubrication.

Temperature Level

It is crucial to know the temperature at which a seal will be operating so that you can choose the brand that can withstand extreme conditions. Leather or PTFE seals are known for their ability to withstand even extremely high-temperature levels.

Type of Fluid

Most rotary shaft seals can withstand interaction with fluids such as water, grease, fuels, and oils. However, knowing the liquid that the shaft seal will have constant contact with can make the seal last longer. That will also contribute to the efficiency and longevity of the surrounding components.

Shaft Speed

The other consideration is the speed in which the rotary shaft seal will be moving. After all, no one wants a seal that will suffer from spiraling and abrasions after being subjected to an extremely high speed.

With dozens of rotary shaft seals available on the market, it can be challenging to know what brand suits your machinery. That’s why experts are available to help you with selecting the right brand, material, type, shape, and size of a seal. Shaft speed, amount of lubricant, temperature, and fluid are some of the factors that determine the type of seal needed for machinery.
