3 Inch Industrial Heavy Duty Swivel Caster Wheels with Brake, Set of 4 Safety Locking

What to check before you buy

Capacity per caster, times the count

Caster ratings are per wheel. The usual guidance is to divide the total load by the number of casters minus one, so an uneven floor cannot overload a single wheel.

Wheel material against the floor

Soft wheels protect finished floors and roll quietly over debris; hard wheels roll with less effort on smooth surfaces but transmit shock and can mark floors.

Swivel versus rigid layout

Two rigid and two swivel gives predictable straight-line tracking. Four swivel gives maneuverability but is harder to push in a straight line under load.

Mounting pattern

Plate size, bolt hole pattern and stem type are not universal. Measure the existing mount before ordering replacements.

Frequently asked questions

How do I work out the caster capacity I need?

Divide the total weight (equipment plus maximum load) by the number of casters, then apply a safety margin. A common approach is to divide by the caster count minus one, since uneven floors rarely load all wheels equally.

Which wheel material should I choose?

Match it to the floor and the environment. Polyurethane and rubber protect finished floors and absorb shock; phenolic and cast iron take heat and heavy loads; nylon resists chemicals and rolls easily.

Do I need brakes on all four casters?

Rarely. Two braked casters usually hold equipment in place. What matters more is that the braked wheels are positioned so the item cannot pivot around them.

Why does my cart wander to one side?

Commonly a damaged swivel bearing, debris in the wheel, or mixing wheel diameters or materials across the set. Casters should be replaced as a matched set rather than individually.

What is a kingpinless caster?

It replaces the kingpin - the usual failure point under shock loading - with a raceway design. They cost more and are specified for towing and high-impact applications.
