Which is better, roller bearings or journal bearings for tricone roller rock drilling bits ?
We may not be able to know the bearings of the drill bit from the surface of the drill bit, but the quality of the bearings is very important. Bearings are divided into ROLLER BEARING and JOURNAL BEARING. The use of journal bearings and roller bearings in roller drill bits each has its own adva...Read more -
Brief introduction of PDC cutters
Today’s PDC drill Bits Design as a matrix has little resemblance to that of even a few years ago. Tensile strengths and impact resistance have increased by at least 33%, and cutter brazes strength has increased by ≈80%. At the same time, geometries and the techn...Read more -
