❓ 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.
