- Placing set-screws 60¡Ærelative to the radial plane, this type provides
  easy concentric fitting.
- Also 3 or 6 set-screws provide relatively high loosening torque.
- Balance adjusting tap-holes are placed on the back to the axial direction.
- Precisely grinded inner threads, clamping face, trailing rim and
  outer skirt have enhanced accuracy.
