Stainless Steel Materials

Features

  • Reduces torsional forces
  • Can also be used in applications that are required to rotate but not under pressure, such as hose reels
  • Spindle is carried on a roller bearing and has a low friction shaft seal that can rotate at maximum pressure with low torque
