AT LAST...A CASTER DESIGN THAT MAKES SENSE! "EMAXX" by Algood Corporation Compare these features with what you are now using: 1  6/8" diameter heavy duty kingpin, most other caster brands of this size use 5/8" or less. This makes the Emaxx series casters able to withstand extreme abuse. 2  Unique inverted cup over upper raceway, acts like a "umbrella" against dirt, dust & water. 3  Both upper and lower raceways (for swivel) have 5/16" diameter hardened steel load bearings. Most other casters manufacturers use large bearings on the upper raceway but small bearings for the lower. 4 One piece formed caster construction, no traditional welds are used, increasing the life & reliability of all the Emaxx series casters.
