Application-Specific Idler Bearing Seals

SpinGuard® Seal Technology

Superior’s patented next-generation SpinGuard Idler Bearing Seals offer greater protection in applications known to expose idler bearings to fugitive material prematurely.

Application-specific seal configurations have 5+ years of trial and error testing in lab and field settings. Production lead times for idlers outfitted with these special seals are competitive to idlers with traditional seals.
