K60 Pneumatic Rolling Motor

KRAIS Tube Expanders

Key Features

K60 rolling motors control expansion by the accurate measurement of torque. They automatically stop expanding according to a predetermined setting. Torque control prevents over- and under- expansion of tubes, assures uniformly tightened tube joints, and provides maximum holding strength for individual tubes. All K60 motors include torque sensing cams designed and manufactured specifically for tube expanding applications.

  • Strong, lightweight aluminum housings for easier handling and less operator fatigue
  • Rugged drive combines precision control and measured torque output
  • Simple dial-a-torque adjustment collar for easy set up
  • Cushioned shut-off reduces torque reaction
  • Quick change chucks to improve productivity
