CJSC “Mining technologies” manufactures customized centering roller-deck bushings. The products meet the manufacture standards; they have certificates of the international quality management system ISO. The order is delivered to the company by the transport company, which is selected by the customer.
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.
