White and black Polyolefin Caster Wheels are crafted through injection molding, creating a one-piece, solid, and hygienic design. These wheels excel in wet and corrosive settings, displaying exceptional resistance to a wide range of liquids, acids, and bases.
Their suitability for dairy farms is particularly noteworthy, as they withstand the harsh effects of caustic cow manure, outlasting many other wheel types in this demanding agricultural environment.

You should never select on the basis of load capacity alone. There is no industry standard for load capacity ratings and they may not include a factor for abuse. Our capacity ratings are below what the casters are capable of carrying because most applications have less than perfect conditions. Please refer to the information shown at the bottom of this page. If you have any doubt as to which wheel or caster is the BEST choice for your application contact us for a recommendation.
