There are several types of coatings for bearings, including polymer coatings, ceramic coatings, metallic coatings, and fluoropolymer coatings. Each type is designed for specific applications—polymer coatings provide self-lubricating properties, while ceramic and metallic coatings offer high-temperature resistance and durability in heavy-duty operations.

Bearing Coatings
Enhancing bearing performance with advanced, durable, and wear-resistant bearing coatings designed to maximize efficiency and longevity.
coating solutions for the bearing industry
The Purpose of Bearing Coatings
Bearing coatings improve the performance, longevity, and reliability of bearings by reducing friction, increasing wear resistance, and providing corrosion protection. These coatings create a hard, wear-resistant surface that prevents abrasion and mechanical wear, extending the lifespan of bearings and reducing maintenance costs.
Bearing coatings like Armoloy also serve as a barrier against corrosive elements, preventing rust and material degradation. Additionally, bearing coatings enhance lubricity, ensuring smooth operation even in the event of lubricant failure, and help distribute loads evenly across bearing surfaces, improving durability and stress management.

Frequently Asked Questions
Coatings reduce friction in bearings by creating a low-friction, wear-resistant surface that minimizes direct metal-to-metal contact. For example, Armoloy Thin Dense Chrome (TDC) features a micronodular surface structure that can retain trace lubricants or function effectively in dry or low-lube conditions.
This reduces frictional drag, prevents galling, and minimizes heat buildup during operation — all of which contribute to smoother performance and longer service life. In high-load or high-speed applications, coatings also protect against abrasion, fretting, and lubricant breakdown, improving bearing efficiency and reliability.
