FAG supply all kinds of rolling bearings used in oil production:
The classical mud pumps are piston pumps. The connecting rods are guided on the crankshaft in special cylindrical roller bearings with split adapter sleeves. The crankshaft is supported in the housing both by spherical roller bearings and by tapered roller bearings.
National Oilwell Varco’s HEX MUD PUMP is a new development. The Schaeffler Group supplies the rolling bearings, cam disk and linear bearings for this pump as well as the relevant condition monitoring system.
