When it comes to casters, consider these.
According to Hamilton Caster:
“If you’re in the caster biz, you know that 3.5-inch to 5-inch-diameter industrial casters are industry standard. Like Honda Civics, they’re everywhere. When they fail, you can swap in new casters and keep the same hardware. But what about industrial casters that can’t fail—like ones that are mission critical for Automated Guided Vehicles (AGVs)? Regular industry-standard casters just don’t have the chops to take a licking and keep on ticking and ticking.
“Well, thanks to Hamilton’s all-new Endurance series, there’s now an industry-standard-sized caster for that. With a maximum load rating of 1,000 pounds per caster, Endurance features the highest rated industrial caster with the same critical dimensions as the industry’s highest volume product class. It’s also the first and only industrial caster series designed with forged kingpinless construction and heat-treated raceways in such a small form factor.
“In other words, Endurance looks industry-standard but performs above-and-beyond. Our engineering pros picked the most common caster size on the market and matched its spec, height and offset with one tough-as-nails design. Endurance’s forged steel construction is perfect for applications that require 24/7 operations and/or are too critical to fail. With 3 ½-inch, 4-inch and 5-inch diameter options, the Endurance Series is offered in both single wheel, dual wheel and stainless steel versions. Want even more stability and higher capacity without taking up a lot of room? Select the Endurance dual wheel models.
“Endurance’s only dimensional difference lies in its wheel width and leg thickness. To achieve a higher load rating and durability, Endurance features two-inch-wide wheels and 1/4-inch-thick legs (other brands have 1 1/4-inch-wide wheels). You’ll pay a little more up front for its premium construction and ultra-rugged design—then reap the savings in the long run while it runs and runs without breaking a sweat. Endurance is intentionally designed and over-engineered for applications where replacement is cost-prohibitive.”
