Tough. Even under pressure.

High-performance dry sliding bearing material: deva.metal®

deva.metal® is a high-performance sliding bearing material. Manufactured using powder metallurgy, the deva.metal® system is based on four main groups – bronze, iron, nickel, and stainless steel. These contain solid lubricants, e.g., graphite, manganese sulfide or molybdenum disulfide, which are uniformly embedded in the metal structure. As a material manufactured by means of powder metallurgy, deva.metal® is very dimensionally stable. However, our special sintering methods enable very high physical durability, particularly when subjected to compressive stress.

The requirements of the specific application determine the volumetric content of the solid lubricant, its type, and form. The determining factors include the sliding speed, the specific load, the temperature, and other application-specific operating conditions. Very specific tribological properties can therefore be produced.

deva.metal® offers a number of advantages

  • High static and dynamic loading capacity
  • Unproblematic use in dusty environments
  • Temperature-resistant from -200 °C to +800 °C
  • Can be used in corrosive environments
  • Electrical conductivity without electrostatic charging effects
  • Maintenance-free even in dry operation, unlike conventional bearing materials
  • RoHS-compliant
