Frequently Asked Questions (FAQs)

1. Why are lip seals used?

Lip seals are used to exclude contaminants and retain lubricants in various applications. They function by maintaining friction and can be used in slow-moving equipment to high-speed rotation, as well as in extreme temperatures.

2. What are the disadvantages of lip seals?

Lip seals have limitations as they don't withstand high pressure well and can cause shaft damage in a short period of time. Additionally, they lack government certification required in certain industries like meat, poultry, and dairy processing.

3. How long do lip seals last?

The lifespan of lip seals can vary, but most seal manufacturers state that operating within the specified limits can result in a minimum lifespan of two years. Some seal types, like those specified in Standard API 682, may provide a longer lifespan of up to three years.

4. What are the advantages of lip seals?

Lip seals offer several advantages, including custom designs and a wide range of sizes and materials. They are inert to most chemicals, can withstand high speeds, and have low friction, making them suitable for rotating equipment and vibration-prone environments.

5. Is a double lip seal better than a single lip seal?

Both single and double lip seals serve their purpose. The single lip seal contains the lubricant, while the double lip seal has an additional rubber lip to prevent dust or dirt from reaching the shaft. The choice of which seal to use depends on the specific application and its requirements.
