❓ Frequently Asked Questions (FAQ)

Q1: Why use a double lip seal over a single lip?

A1: A double lip seal has an added dust lip that:

  • Protects against external contamination

  • Extends the lifespan of the seal and internal components

  • Is ideal for outdoor, dusty, or wet environments.

Q2: Is the spring necessary in a rotary shaft seal?

A2: Yes, the spring applies consistent pressure to the main sealing lip, ensuring it stays in contact with the shaft surface, even if there is minor shaft misalignment or pressure variation.
