Скачать или смотреть Demonstration of Surface Textured Low Friction Sliding Surfaces

EKK’s surface texturing technology brings two contraries together: extremely low torque* with superior sealing performance*, coupled with surface speed capability in excess of 50m/s.
(* 90+% improvement over conventional mechanical seals)

A textured surface is an uneven, micro structure that is processed to the sliding component.
During rotation, fluid is drawn into the textured surface to generate positive pressures, promoting formation of fluid film and separation of the sliding surfaces. As a result, friction is reduced by 90% or more, compared to the conventional sliding surface.

Furthermore, an optimized texture can also generate negative pressures, preventing fluid leaking passed the sliding surfaces. This achieves leakage reduction of over 90%.
