Product Features
  • Dynamic Dual-Lip Architecture & Hydrodynamic Hydro-Sweep Flutes: Features a dual-lip architecture combining a hydrodynamic main sealing lip and an dust/exclusion auxiliary lip. The micro-patterned main lip actively pumps fluid micro-films back into the pump cavity under dynamic shaft rotation, while the primary scraper lip blocks ambient dust and abrasive debris from entering the sealing interface.
  • Spring-Energized Radial Tension & Dynamic Shaft Deflection Runout Control: Incorporates a precision garter spring to deliver consistent radial contact pressure against the rotating drive shaft. It dynamically conforms to micro-scale shaft runout and radial deflection caused by heavy torque shocks at high operating speeds (2000+ RPM), preventing localized pressure drops and fluid weep.
  • Low-Friction HNBR/FKM Compound & Elastomeric Shaft Protection: Formulated with high-grade, friction-reduced HNBR/FKM elastomer designed to withstand high friction flash temperatures during momentary cold dry starts. Its low friction coefficient minimizes wear and prevents scoring or grooving on expensive drive shaft journals over extended service intervals.
