Advanced lubrication & pressure compensation
Critical to roller cone bearing reliability are:
- Grease that withstands the extreme unit loads
- Pressure compensation that maintains grease and seal integrity
RockForce™ and TuffCutter™ bits from ReedHycalog include the following proven technology:
Proprietary synthetic grease
- Greater film thickness - higher load capacity
- Higher heat capacity - cooler running
- Greater oxidation stability - longer life
- Better thermal stability – longer life
Improved tolerances and clearances
- Improved tolerances and clearances
- Reduced spalling and fatigue - more consistent bearing performance
VentRite™ pressure compensation
- More robust design better withstands pressure fluctuations
- More reliable "vent to the bowl" design is less likely to clog
