Caster Options Explained

Heavy Duty Casters

Best for industrial carts, racks, machinery, and equipment that require higher load capacities. These casters are built for demanding work environments where durability and long-term performance matter.

Swivel Casters

Designed for easier turning and maneuvering in tight aisles, work areas, and warehouse spaces. Swivel casters help equipment move more freely when directional control is important.

Fixed / Rigid Casters

Help equipment move in a straight line with better tracking and control. They are ideal for heavier loads, longer travel paths, and applications where side-to-side movement is not needed.

Stem Casters

Common on equipment, fixtures, carts, and workstations that use a stem-style mounting connection. They are a good option when a plate-mounted caster will not fit the existing equipment design.

Ideal Applications

Moving Carts Through Warehouses And Stockrooms

Supporting Racks, Dollies, And Material Handling Equipment

Adding Mobility To Workstations And Tool Cabinets

Replacing Worn Casters On Industrial Carts

Improving Maneuverability In Tight Facility Spaces

Supporting Heavier Loads In Manufacturing Areas

Rolling Equipment Across Concrete Warehouse Floors

Using Specialty Casters In Washdown Or High-Temperature Areas

Frequently Asked Questions

What Type Of Caster Do I Need?

The right caster depends on the load weight, floor surface, mounting style, and how the equipment needs to move.

  • Swivel Casters
    Best for carts and equipment that need to turn easily in tight spaces.
  • Fixed / Rigid Casters
    Best for straight-line movement and better tracking over longer distances.
  • Heavy Duty Casters
    Best for industrial carts, racks, machinery, and higher-capacity applications.
  • Stem Casters
    Best for equipment that requires a stem-style mount instead of a plate mount.

If you are unsure, start by checking the required load capacity, wheel material, mounting type, and floor conditions.

How Do I Choose The Right Caster Capacity?

Add the total weight of the cart, equipment, and load, then divide that weight by the number of casters supporting it. It is usually best to choose a caster with extra capacity above the calculated weight to account for uneven floors, impacts, and daily use.

 

For example, if a loaded cart weighs 1,000 lbs and uses four casters, each caster should be rated for more than 250 lbs.

What Is The Difference Between Swivel And Rigid Casters?

Swivel casters rotate, making it easier to turn and maneuver carts in tight spaces. Rigid casters do not rotate, which helps equipment move in a straight line with better control.

 

Many carts use two swivel casters and two rigid casters for a balance of maneuverability and tracking.

What Wheel Material Is Best For My Floor?

The best wheel material depends on your floor surface, load weight, and work environment. Polyurethane wheels are popular for concrete floors because they roll smoothly and help protect the floor.

 

Rubber wheels can reduce noise and vibration, while metal or phenolic wheels may be better for heavy loads, high temperatures, or rougher industrial use.

When Should I Use Heavy Duty Casters?

Heavy-duty casters are recommended for industrial carts, machinery, racks, platform trucks, and equipment that carries heavier loads. They are designed for demanding environments where strength, durability, and long service life are important.

 

They are also a good choice when the caster will be used frequently or exposed to impacts, rough floors, or heavy daily use.
