Fiber-filled phenolic resin, molded under extreme pressure, gives Hamilton Plastex wheels the ability to carry heavy loads without damaging floors in intermittent service. They are non-marking, resist corrosion from oil, water, grease and commonly used acids or solvents, and will not spark. They can be operated continuously in temperatures ranging from -50° to 260° F and intermittently to 300° F.
Roller bearings are standard in all wheels (choice of straight or precision tapered roller bearings in most of the larger sizes). Tapered bearing wheels feature superior -anti-slip- installation: bearing cups are press-fit into the counterbored ends. All wheel sizes 5" and above (except 6" x 2-1/2", 6" x 3" and 8" x 3") have ball-check pressure lubrication fittings.
