Review on T REX CASTER 2 13UNC1 Polyurethane Capacity by Wayne Drakh

Had to send them back as the stem was too short for my purpose (replacement for knee carriage casters). However, impressive quality. The bearings have shielding to keep dirt out and they have a matching nut on the end of the shaft under the take-up reel instead of the usual swaged/swaged mount. These wheels tend to have a flat contact profile (the ones I've used have a more pronounced rounded contact profile, like in-line skate wheels).
