Description

Bearing Structure
Non-sealed roller bearing. Drilling fluid can enter the bearing directly for cooling;
Balls lock the cone which reduces the probability of cone dropping to minimum
Seals and Lubrication
The advanced metal seals improve the reliability and stability of the bearing sealing. Pressure difference type compensating system assures a good greasing lubrication function.
