Picking the right caster can make or break the performance of your equipment. The wrong caster can lead to damaged floors, employee strain, or even costly downtime. The good news? With a few key measurements and insights, you can choose the perfect caster for your needs every time.

Step 1: Determine Load Capacity

Calculate the total weight your equipment will carry—including both the equipment and its maximum load—and divide by the number of casters. Add 25% for safety.
Example: If a cart weighs 400 lbs and carries 600 lbs, divide 1,000 lbs by 4 casters = 250 lbs each. Add 25%, and you’ll need casters rated for at least 312 lbs.

Step 2: Choose the Right Wheel Material

Different surfaces and environments demand different wheel types:

• Polyurethane: Durable and floor-friendly; best for most applications.

• Rubber: Quiet and grippy but less durable.

• Steel or cast iron: Great for extreme loads but hard on floors.

• Nylon: Lightweight, moisture-resistant, and ideal for wet environments.

Step 3: Match the Floor Type

Flooring makes a big difference:

• Concrete or tile: Polyurethane and rubber protect against vibration and damage.

• Uneven or outdoor surfaces: Pneumatic wheels absorb shock.

• Cleanroom or food prep areas: Non-marking wheels are a must.

Step 4: Pick a Mounting Type

• Plate mount: Provides stability for heavy-duty use.

• Stem mount: Easy to replace and ideal for furniture or light-duty carts.

• Expanding adapter: Perfect for tubular frames.

Step 5: Consider Movement and Brakes

Do you need fixed, swivel, or both?

• Swivel casters make turning easier.

• Rigid casters provide stability.

• Total lock casters stop both the wheel and the swivel at once.

Bonus Tip: Think About Environment

Casters that face chemicals, moisture, or high temperatures require specialized materials like stainless steel or high-temp grease.

Choosing the right caster starts with understanding your environment and needs. With the right combination of load rating, wheel type, and mount style, you’ll get equipment that moves effortlessly and lasts for years.
