Technical features

The centering (alignment) bushings are divided into two main types - roller (with bearings inside) and BHSG bushings (slide bushings) – without bearings.

The centering roller bushing is designated for:

  • Setting the right direction for the drill rod axle;
  • Reducing the torque losses of the drill rig;
  • Reducing wear of the drill rod;
  • Increasing lifetime of the roller-cone bit.
