Title: ROTARY FACE SEAL WITH MAGNETIC REPELLING LOADING
Abstract:
The rotary face seal (100) with magnet loading replaces known spring mechanisms with magnetic technology that provides a consistent load with minimal variation, which is not affected by natural frequency and material fatigue due to cyclic loading. This improves seal performance and service life by eliminating the issues that compromise the effectiveness of conventional spring mechanisms. The repelling pusher magnetic technology (120a, 120b) is advantageous because it replaces the spring mechanism within a self-contained stationary cartridge with a pusher type magnetic assembly configuration (120a, 120b) that enables exact drop-in replacement of existing seal configurations.
