PremH™
Thermal Stability
PremH™ maintains high mechanical strength and low deformation at elevated temperatures, ensuring sealing integrity and reliable performance at high RPM and WOB.Advanced Chemical Resistance
Provides high resistance to tearing, abrasion, and cracking, maintaining sealing performance under vibration, load, and high rotational speeds.Extended Operational Reliability
Increases the MTBF of the bearing and lubrication system, extending bit life and reducing unplanned replacements.ThermF™
Thermal Stability
ThermF™ ensures stable performance at temperatures of 180–230°C (up to 250°C intermittently), reducing wear, leakage, and lubricant degradation.Advanced Chemical Resistance
Provides high resistance to abrasion, tearing, and wear under intensive loads and vibration, maintaining sealing integrity even under high pressure differentials and fluctuating temperatures.Lower Lifecycle Cost
Extends MTBF by maintaining lubrication and protecting bearings from wear and aggressive media, resulting in longer drilling intervals, fewer bit replacements, and reduced operational costs.Endura™
The dual elastomer sealing system is an advanced solution designed for the most demanding drilling conditions. Two independent barriers effectively protect the bearings, ensure stable lubrication, and significantly extend bit life, even in highly abrasive environments. High-performance elastomers (PremH™ / ThermF™) provide excellent chemical resistance and thermal stability across a wide temperature range, minimizing the risk of leakage.
