Duralast® Wheels (D)

Capacity Range: 475 - 9,000 lbs.

 

#W-620-DB-1/2
 
 
Duralast ® - the protective wheel that wears like steel - is liquid cast to a thickness of approximately 1/2" and chemically bonded onto heavy-duty iron wheel centers. The distinctive green treads are chemically inert, non-sparking, non-conductive, impervious to ozone, grease and most oils & solvents, and will not mark floors. Duralast® Wheels are also guaranteed against tread separation for one year in ordinary free-wheeling applications (contact factory for excepted applications).

They are available without bearings, with straight roller bearings, precision ball bearings, or with precision tapered bearings as listed below. All wheel sizes with straight and tapered roller bearings over 5" diameter include ball-check lubrication fittings in the hub.

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