Cassette Seals – The Ultimate Shaft Protection Solution for Extreme Conditions

Cassette Seals – Maximum Shaft Protection and Durability in Extreme Conditions

What Are Cassette Seals?

Cassette seals (RWDR-Kassette Seals) are advanced rotary shaft seals designed for demanding applications, offering sealing, contamination protection, and self-lubrication in a single unit. Unlike standard radial shaft seals, cassette seals integrate a multi-lip labyrinth system, pre-lubricated channels, and internal raceways, ensuring extended durability and superior protection against external contaminants.

With a completely enclosed structure, cassette seals provide exceptional resistance to dust, mud, sand, and water, making them the preferred choice for heavy-duty machinery and vehicles operating in harsh environments.


Key Benefits of Cassette Seals

No Special Shaft Preparation Required – Unlike standard shaft seals, cassette seals do not require the shaft to be hardened or ground, reducing installation costs.
Maximum Contaminant ProtectionPrevents the ingress of dust, dirt, water, and other contaminants, significantly extending service life.
Integrated Lubrication – The built-in grease pocket reduces friction and wear, enhancing operational efficiency.
Optimized for Harsh Environments – Specifically designed for agricultural, construction, and off-road machinery, ensuring optimal sealing even in the most demanding applications.


Types of Cassette Seals by CORTECO

Cassette seals come in different performance levels, depending on the required speed, protection level, and resistance to contaminants:

? S1Low rolling resistance, speed up to 9 m/s
Ideal for passenger cars and light commercial vehicles, offering basic protection against contaminants with minimal friction.

? S2Medium-level protection, speed up to 7 m/s
Used in construction and agricultural machinery, providing enhanced sealing against dirt and debris while maintaining moderate rolling resistance.

? S3Highest-level protection, speed up to 6 m/s
Designed for off-road vehicles, tractors, and heavy-duty equipment, offering maximum defense against extreme dust, mud, and water exposure.
