2021-8-21 · Roller cone bits. Grand (GRD) These roller cone bits are designed for drilling upper well sections, or surface hole drilling. Without sealing elements in the bearing, it is possible to maximize the journal and achieve full circulation in the bearing which is highly important for torque reduction, rapid cooling and bearing life extension.
2012-1-25 · The even distribution of forces on the Rollercone bearings is a big factor in the extremely long life of the bearings. The roller bearing design minimizes frame deflection so all crushing energy is directed to the product. Concentrated bending stresses that occur in shaft type cone crushers are evenly distributed in the Rollercone.
