Chinese Professional Rock Drill Pipe - Rotary Deck Bushing – TDS

This rotating bushing assembly has 3 bearing races that allow for the inner sleeve to rotate within the outer body. TDS deck bushing provides high performance combined with longer service life. This type of deck bushing is used primarily in rotary applications where the rotation speed is considerably higher than that of a DTH application.
