The features of our floating seals as follow: 1) Material: 15% Cr 3% Mo cast iron2) HRC: 65-723) Out Diameter: 50-865mm4) Life: over 4500 hours 5) Working face precision: less than 0.015um 6) Flatness: 0.1um-0.2 um; 7) Pressure: 1.0-1.7MPa/cm2 (max.) 8) Temperature range: -20-90 Degree 9) Circumferential speed: 3m/ sec (max). 10) Character: high hardness,wear resisting,anti dirty ability, corrosion resistant. Our products are made of high alloy steel. The rough cast, through hot forming, is of high strength, grind the uneven edge. the metal structure is improved through repeated heat treatment, thus the product wears well and the precision is achieved.
