Frequently Asked Questions (FAQs)
1. What are the different types of bearing isolators?
There are several types of bearing isolators available, including those designed for steam turbines, paper machine rolls, pillow blocks, and more. Each type is specifically designed to meet the needs of different applications and environments.
2. Is a bearing isolator better than a lip seal?
Yes, a bearing isolator is considered to be more effective than a lip seal. While a lip seal typically has a life expectancy of 6-12 months, a bearing isolator can last 5 years or longer, making it a more durable and reliable option for sealing bearings.
3. What can I use instead of a labyrinth seal?
Instead of a labyrinth seal, you can use pocketed damper seals. These seals offer 50 to 100 times more damping compared to conventional labyrinth seals. They have individual teeth with dams that provide damping and prevent gas swirl, making them a superior alternative.
4. How do you install a bearing isolator?
To install a bearing isolator, you need to lubricate the gasket o-ring on the outer diameter of the isolator. Then, using a hand arbor press, you can install the bearing isolator assembly. It's important to check for proper orientation, ensuring that the expulsion port is at the 6 o'clock position. A puck or square blank should be used to evenly press the bearing isolator into the cover.
