RockForce™ Bearing System
Directional drilling and the use of downhole motors has increased dramatically. Torque and energy outputs
have risen as much as ten fold. Result: greater demand on bits and bearings.
The new RockForce™ bearing has been completely reengineered with optimal design, manufacturing, and
material technologies to meet these new demands. The result is a series of roller cone bits that deliver
proven, superior field performance, consistently.
RockForce bearing technologies include:
High-energy cone retention
- Encapsulated ball race design provides lower contact stress – improved load capacity and reliability
Improved tolerances and clearances
- Reduced axial cone movement - increasing seal life
- Reduced spalling and fatigue - more consistent bearing performance
Precision machined, silver-plated surfaces
- Superior solid lubricant for sliding surfaces - reduced friction, longer life
- Specific design selected to suit the size and the application
Seal Design
- Optimized for the bearing size- increased life and consistency
Advanced lubrication system
- Specially formulated, synthetic, proprietary grease that withstands the increasing drilling
demands - maintains its properties for longer life
- Ventrite™ pressure compensation system vents to the bowl of the bit reducing seal stress and
grease contamination - longer bearing life
