Application-Specific Idler Seals

SpinGuard® Seal Technology

Superior’s patented next-generation SpinGuard Idler 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.

Four NEW Application-Specific Idler Seal Options

conveying idlers




Wash or dredge processes.
Frequent washdowns.


Special double contact seal defends bearing from moisture penetration.




Crushing and screening dust with excessive fines.


Oiled and contact seals protect bearing from dry particles and grit.




Overland or long distance material handling sites.


Seal reduces drag and roll resistance for less horsepower at startup /operation.




Washed sand, fines removal or dredging. Most extreme conditions.


Combination of design characteristics from wet and dry seals for ultimate bearing protection



APPLICATIONS: Traditional material handling not described above. Typically 80-90% of applications.

BENEFITS: While testing our application specific models, we redesigned our standard for the best bearing protection yet.
