CLEVELAND Grease Seal for Wheel Assemblies SKU: CLV-GRSSEAL

A grease seal, often called an oil or dirt seal, is a type of seal utilized to retain grease in a case or housing. Grease seals close spaces between stationary and moving components in mechanical equipment, helping prevent lubricant escape. Preventing harmful containments from entering machinery is another critical function of a grease seal. Oil and grease seals are available in numerous lip materials. Popular materials include felt, leather, urethane, nitrile, polyacrylate, ethylene-acrylic or polyacrylic, silicone, fluoro-elastomer, tetrafluoro-ethylene propylene and PTFE. Cleveland Grease Seals are intended for use in Cleveland Wheel Assemblies.

A grease seal, often called an oil or dirt seal, is a type of seal utilized to retain grease in a case or housing. Grease seals close spaces between stationary and moving components in mechanical equipment, helping prevent lubricant escape. Preventing harmful containments from entering machinery is another critical function of a grease seal. In a typical application, the grease seal is installed adjacent to a bearing, sealing in or sealing out, as necessary, the various liquids, gases or solids encountered by the particular mechanism. Oil and grease seals are available in numerous lip materials. Popular materials include felt, leather, urethane, nitrile, polyacrylate, ethylene-acrylic or polyacrylic, silicone, fluoro-elastomer, tetrafluoro-ethylene propylene and PTFE. Use of one material over another is application specific, as materials will have different temperature and speed ranges. Grease seals also come in numerous constructions. Of particular note is the number of lips, with single and double lip being the most popular. Many popular styles of grease seals will utilize a spring on the lip to increase sealing capabilities. Some grease seals have a coated metal casing with a “rubber” lip while other seals will be a uniform with the lip material. Available in a wide array of sizes, both inch and metric, most grease seals are interchangeable between manufacturers. Critical dimensions on a grease seal include the inside diameter or bore (the OD of the shaft the seal rides on), the outside diameter (often called the housing bore) and the width. The ID and the OD are the most critical dimensions, as it is the grease seal lip that actually does the sealing. In most applications, a replacement seal that is thinner in width than the original will work, as it will still fit into the grove provided. Depending on this groove dimension, on occasion, a wider replacement seal will also work. Grease seals should not be confused with U Cups or Packings that are designed to handle higher pressure. A standard grease seal is designed to handle 7 or less PSI depending on the manufacturer.

Grease seals are generally the least expensive component in a mechanical system, but they serve to be the most important, as they protect the more expensive components, such as the bearings and gears. The most common failure mode for most bearings is a lack of or improper lubrication. The grease seal keeps the correct amount of lubrication in and the harmful contaminants out. Regularily checking and replacing the grease seal is a part of successful preventive maintenance programs.
