Surface Protection for Bearings and Track Rollers – Effective Protection Against Rust and Wear

To significantly extend the service life of your bearings and track rollers, even under the most extreme conditions, AKT offers high-quality surface coatings under the proven brand name Corrprevent®. Our surface treatments are specially developed to provide optimal protection against corrosion and wear.

Durable Protection and Extended Lifespan Through Specialized Coatings

Our innovative coating systems specifically enhance corrosion resistance – for example in food applications or agricultural machinery – improve wear resistance – such as in high-load start-stop operations – or provide a combination of both properties. Especially in machinery and industrial equipment where bearings and rollers are constantly exposed to stress, the right surface finish not only prevents corrosion but also significantly reduces friction, material wear, and energy loss.

High-Performance Surface Treatments for Best Results

In close collaboration with our long-standing, regularly audited partners, we offer various field-tested coating systems:

  • Zinc Coatings (Corrprevent ZINC®)
  • Zinc Alloy Coatings (Corrprevent IRON®, Corrprevent NICKEL®)
  • DLC Coatings (Diamond Like Carbon – Corrprevent DIAMOND®)
  • Thin Chromium Coatings (Corrprevent CHROME®)

Personalized Consultation for the Ideal Coating Solution

The choice of a suitable coating depends on the specific application and operating environment of your bearings and rollers. Our experienced team is always ready to support you with expert advice to help you select the most effective coating system.
