Featured Wheel Bearings:
Precision Ball Bearings - double sealed, maintenance free, superior rollability aids manual applications, not recommended if shock loading is prevalent.
Precision Tapered Roller Bearings - best for most severe heavy duty and power-towed applications.
Straight Roller Bearing - traditional anti-friction bearing, best for manual applications where shock loading (but no side thrust) is prevalent.
