Main Components of an Oil Seal:

1. Metal Case: Provides structural support and keeps the seal in place.
2. Elastomeric Lip: The flexible sealing surface that contacts the shaft to prevent fluid leakage.
3. Garter Spring: A small spring embedded in the lip to apply pressure, ensuring a tight fit around the shaft.

Key Functions:

• Sealing: Retains lubricants (like oil) inside machinery to reduce friction between moving parts.
• Protection: Prevents external contaminants from entering, protecting parts from wear or damage.

Oil seals are essential components for ensuring the smooth and reliable operation of equipment with rotating parts, commonly found in industries like automotive, manufacturing, and aerospace.
