Guidance to choose the right caster wheel

Ergonomics, worker safety, noise, productivity, and cost savings, are some challenges you must be faced while choosing the right heavy-duty industrial wheel for your material handling application that can be a big part of the solution.

When choosing an air cargo casters, you need to consider some main point to choose the right caster wheel.

Wheel size

When you think size, think load. If you need casters that can support a maximum weight of 10,000 pounds. If you have casters on all four corners of your cart or rack, you will need heavy duty wheels and casters that are rated to hold maximum pounds.  This added capacity is your margin of safety.  To compensate for unbalanced or shifting loads, you should shoot for about 30% over your maximum weight.

This is also where increasing the wheel diameter comes into play. Increasing the wheel diameter means less effort to start rolling and to keep the wheels rolling. While increasing wheel diameter is advantageous, increasing wheel width is not. Wider wheels increase surface pressure, making them more resistant when you are trying to switch directions.

In general, the heavier the desired caster load capacity, the harder the wheel material will be. But harder wheels have a higher potential to damage your floors. Heavy duty wheels and casters with softer treads are more resilient and offer the most protection to your floors. These types of casters and wheels can also reduce the accumulation of small obstructions like metal shavings, but the tradeoff is that they may be too light-duty for more rugged applications.

For these reasons, solid polyurethane wheels trends offer one of the best compromises between load capacity and floor protection. Even better, there’s a wide variety of ways that polyurethane can be engineered to ensure that your casters and wheels are both ergonomic and durable.

The Caster rig.

A properly manufactured, long-lived industrial medium heavy duty casters that require little upkeep depends mainly upon three key design choices. These are a properly-sized swivel section; hot-forged vs. cold-stamped swivel sections; and leg thickness and width.

A properly sized swivel section generally refers to the ball bearing interface between the top plate and the yoke base which comprise the swivel section. The ball bearings between the top plate and the yoke base are arranged in a predetermined radius. The raceway circumference and the ball bearing size determine the carrying capacity of the swivel section.

Once you’ve determined the appropriate size of the swivel section, you must consider leg size. The thickness of the leg material and leg width will determine leg size.

The leg impacts the caster application in three significant ways.

  1. The thickness and width of the leg supports a static load
  2. The leg thickness impacts the amount of side thrust the caster can withstand.
  3. The leg width impacts the level of force a caster in a trailing position can withstand

 Because of these considerations, sizing both leg thickness and width correctly is essential to support loads safely while at rest and while moving.

The Final Take

The third consideration also involves the swivel section. Swivel sections are manufactured by cold-stamping or hot-forging. The cost, quality, and strength of your heavy-duty wheels and casters vary widely depending on the method used. Cold-stamping is inexpensive and restricted by the thickness of the metal. For industrial medium heavy-duty casters, cold-stamping is generally limited to 0.25-inch steel plates. The more expensive hot-forging uses much thicker plates, in the range of 0.875 inches.
