Combi and Kombi Simmerring Seals from GRN® and Corteco – A Detailed Technical Guide

Combi and Kombi Simmerring seals are key components in mechanics, used across various industrial and automotive applications. Their innovative design and high-quality materials make them indispensable for protecting components from contaminants, moisture, and leaks. In this article, we will take a detailed look at the seals from GRN and Corteco, focusing on their features, applications, and technical aspects.

What Are Combi and Kombi Simmerring Seals?

Combi (or Kombi) seals are complex sealing solutions that combine the functions of traditional Simmerring seals with additional protective properties. In addition to the classic sealing ring, these seals often feature extra elements such as dust lips that guard against contaminants and reinforced shields that enhance their resistance to external factors.

Structure of Combi and Kombi Seals

Each Combi and Kombi seal consists of the following components:

1. Outer Casing: Protects the interior of the seal and provides structural stability.
2. Sealing Ring: Ensures the tightness of the rotating shaft, effectively preventing oil or grease leaks.
3. Sealing Lip: Specifically designed to limit the entry of contaminants and moisture into the mechanism.
4. Spring: Maintains constant pressure on the sealing lip, ensuring long-lasting sealing performance and minimizing the risk of failure.
5. Dust Lip: An additional element that protects against dust and other contaminants.

GRN Seals – Innovation and Durability

GRN is a brand renowned for producing high-quality seals, including Combi and Kombi Simmerring seals. Their seals are designed to meet rigorous quality and technical standards.
