Emerson Bearing, a Boston, MA-based bearing company catering to niche markets nationwide and the sister company of Action Bearing which serves the New England market, offers a complimentary, “how to” guide for choosing the correct bearing seals.
Equipment downtime and reduced component life are a few consequences and potential costs of using the wrong seals on many types of industrial equipment.
Emerson Bearing offers an effective guideline on how to choose the correct bearing seals
in a “Guidelines for Bearing Seals” complimentary guide available for download from their website, EmersonBearing.com.
The comprehensive guide includes information about selecting the right seal elastomer compound, sealing system preparation, basic seal designs, and more.
Steve Katz, president of Emerson Bearing explained, “Oil seals are vital to the daily operation of most factories and a wide range of industrial and commercial equipment. They are critical components that help keep equipment from breaking down, and allow production equipment to better withstand severe environments. Oil seals help ensure consistent, reliable operation without the risk of damage from leaks.”
Keeping the lubricant in and keeping dirt and contaminants out of rotating components is key. With correct installation, oil seals can also prevent seal leakage and maintain the lubricity of a bearing to ensure that the rotary shaft and its bearings remain fully functional.
Oil seals are available in imperial and metric dimensions for both single- and double-lip design. Motors, Mechanical Hydraulic systems, pistons, and pumps utilize oil seals to protect internal components. Depending on the application, there are various material, size, and configuration options to best fit your needs.
Generally, oil seals vary in materials and types based on the corresponding application. Common materials include: Nitrile Buna-N 70, Fluoropolymer, Silicone, and Polyacrylate.
The benefits of oil seals include: Low levels of friction; compact size and light weight; reliable, rugged performance even under harsh conditions or extreme temperatures; simple construction; and versatility.
