Recommendations for use

  • The rotational speed and power output should not fall below or exceed the specified ranges.
  • With low power output requirements, less than 800 watts, it is possible to fall below the rotational speed range.
  • The radius of curvature should not be smaller than 140 mm.
  • The spiral added to core SE 7 ZGU provides very smooth running for flexible shaft BW 7 ZGU (2 m), particularly in the upper rotational speed range.
