Video: Replacing an HRS split seal

Seals keep contaminants out and lubricants in. They protect parts of machinery like bearings or gearboxes, preventing downtime. In this video, SKF engineers replace a specific seal designed to deal with the demanding conditions in a wind turbine. But many of these steps are applicable in other applications.

Choosing the right seal for your application is one of the most important steps in avoiding potential damage and ensuring a proper fit. Important factors when deciding on the right seal include size, operating temperatures, lubricant, pressures, and forces. Once you have chosen the right seal, the next step is to install it correctly. Here are a few important tips to keep in mind when installing a seal:

  1. Use a service professional with the right tools.
  2. Inspect the old seal for signs of leaks.
  3. Wipe everything clean before seal replacement.
  4. Apply grease to prevent abrasion and improve durability.
  5. Install the new seal with care.

The installer should be well-trained and have the proper tools. An important first step is the inspection of the old seal for damage and wear spots before even removing it. Once the old seal is removed, wiping everything clean allows for a full inspection of the system. Grooves and nicks can have a negative effect on new seal performance, so the inspection of the machine is essential. Once grease is applied the new seal is ready to be inserted it is important to use the proper tools to prevent damage during replacement.

Following these best practices will help improve longevity of seal life, while minimizing unplanned downtime.
