A Groundbreaking Rotary Seal That Redirects Grease Back Where It Belongs


To cost-effectively prevent leaks in a main bearing that was not originally designed to accept traditional seals.


System Seals developed an abrasion-resistant, helical-style seal that redirects leaking grease back toward the raceway as the turbine spins.


The new design stopped main-bearing leaks in the field and prevented the wind turbine manufacturer from redesigning the main bearing for new builds. The solution provided significant overall cost reductions.
