Most roller bearings are equipped with seals that are only able to keep out some dust. These seals are low cost and will degrade after a short period of time. They are sensitive for seawater, UV light and Ozone.
As these are all conditions of significant important in offshore applications like cranes and cable sleeves, AST developed a new generation seals resistant to all these environmental conditions. Lifetime have proven to be up to 10 times the original seals.
We have a complete series of dimensions that will fit every brand and every dimension.
When necessary we install the seals for you to avoid damage on the bearings or seals.
