Slewing Bearing For Rock Drilling Machine
A rock drill is a tool used to directly mine stone. It drills blastholes in rock formations so that explosives can be put in to blast the rock, so as to complete the mining of stone or other stonework. In addition, the rock drill can also be converted into a breaker for breaking hard layers such as concrete. The slewing bearing used in the rock drilling machine is an internal tooth single-row ball slewing bearing or a cross-roller slewing bearing, and the teeth are quenched. The main function is to support the upper cab and the mechanical arm and other mechanisms, and to control the rotation of the cab and the mechanical arm.
