• Radial Seal Design Guide Parker Hannifin

    In most radial seal applications seals can be subject to rolling and twisting during installation and consequently cause seal failure during operation. This phenomenon is commonly known as spiral failure. The double chamfer seals and Drings have flat bases and thus can prevent the spiral failure mode in many radial applications. Double Chamfer ...

  • Control method for centering rolls in radialaxial ring ...

    Mar 12, 2014· The control method of centering rolls was developed to ensure the circularity of rings and remove the process instability during a radialaxial ring rolling (RARR) process. The position control method is determined by the growth velocity of rolling rings and mathematical correlations among the key process variables, such as ring geometries, roll shapes, and feed rates of rolls.
