Hamilton® Plastex Wheel 12 x 3 - 1" Roller Bearing

A fiber filled phenolic resin, molded under extreme pressure, gives this wheel 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. Can be operated continuously in temperatures ranging from -50 to 260 degrees F and intermittently to 300 degrees F.
