Cellasto® seals for greater protection and durability

Standing up to wear and tear can be grueling, but in your machinery, it shouldn’t have to be. Cellasto® provides durable and high-performance protection, especially in assemblies with relative movements such as rotative bearings. 

That’s why trailblazers worldwide are applying it in the design of their dynamic seals for a wide array of applications, from mining and construction to printing and medical equipment.

What are dynamic seals?

Dynamic seals protect valuable, high precision bearings from water, grit, and other harmful materials, while also keeping vital lubricants inside. Moreover, Cellasto® can store grease or oil, enabling long-lasting lubrication of sensitive metal surfaces. 

With both high compressibility up to 35% static pre-load and low lateral expansion under compression, Cellasto® provides longer-lasting protection by maintaining the contact force needed to reduce wear. Not only that, but this microcellular polyurethane foam stands up to friction better than conventional elastomers without adding resistance, so the material itself lasts longer.

In addition, Cellasto® provides dependable, consistent protection at both high and low temperature extremes of operation and environments. Therefore, designing your machinery with Cellasto® will provide unparalleled durability and boost your product’s competitive edge.
