Oil seals keep contaminants separate from the lubricants that keep rotating shafts and precision bearings in good working order. Oil seals are also known as rotary shaft seals, lip seals, and shaft seals.
Emerson Oil seals
Inch Measurement Oil Seals: These seals provide essential functions in the majority of industrial equipment and factories. Various lip materials are available to suit design requirements such as temperature and chemical resistance, including nitrile for low-temperature applications and Viton for high-temperature and low-compression operations.
Metric Oil Seals: Oil seals are available in both imperial and metric dimensions for single- and double-lip designs.
Garlock Isolator Style Oil Seals: These seals provide a suitable solution for applications in harsh environments. Advantages include no metal-to-metal contact, a single-piece design, no shaft wear, and simple installation. They are appropriate for use with most Goulds pumps and available in non-metallic models from ISO-GUARD or metallic varieties from GUARDIAN.
Benefits of Oil Seals
Properly installed, an oil seal will help keep machinery in perfect working order. Its primary functions include retaining or separating fluids, maintaining a bearing’s lubricity, preventing seal leakage, and preventing the entry of foreign contaminants. Other benefits of Emerson Bearing’s oil seals include:
- Easy assembly
- Long shelf life
- A superior substitute for standard seals
- Low friction properties
- Good performance under extreme environments.
Applications of Oil Seals
Oil seals are used in any industrial application that has a rotating or moving part assembly. This includes:
- Engine manufacturing
- Off-highway jobs
- Oil refineries
- Power transmission
- Electrical motors
- Gear boxes
- Industrial pumps
- Customized equipment.
It is important to choose the right type of oil seal for a given application, as it may need to address specific operational concerns such as:
- Low or high temperatures
- Heat resistance
- Low compression
- Chemical resistance
- High abrasion resistance.
Choosing the wrong materials for an oil seal may result in premature wear, lip hardening, cracks, swelling, and subsequent expensive damage to the machinery in which the seal is used. It is therefore vital to gather all relevant data and consult with experts before purchasing to match the right type of oil seal with your application.
Common lip materials available for use in our oil seals include:
Depending on the application, premium lip materials may need to be used, such as Ethylene-acrylic (Varmac®). This material features good abrasion and dry running capabilities, higher heat capabilities than nitrile and polyacrylate, and better low-temperature performance than polyacrylate.
