Key Features of SND Oil Seals

Dual-Lip Sealing System

SND oil seals are designed with a double-lip structure:

• Primary sealing lip retains lubricating oil and grease
• Secondary dust lip prevents entry of external contaminants

This ensures strong sealing performance and extended machine life.

Metal Reinforced Construction

Each seal features a high-strength metal case (skeleton design) that provides structural stability and ensures a secure fit inside the housing, even under high-speed rotation and pressure.

Garter Spring Technology

A precision garter spring is fitted on the sealing lip to maintain constant radial pressure on the shaft, ensuring consistent sealing performance and leak prevention.
