How to Choose the Right Medical Caster Wheel

Selecting the correct medical caster wheel is not simply a matter of choosing a wheel diameter or load rating. The right caster must match the equipment’s weight, operating environment, floor surface, cleaning procedures, mobility requirements, braking needs, and expected service life.

A caster that is too small may increase rolling resistance and wear prematurely. A caster that is too hard may create noise and damage hospital flooring. An inappropriate brake system can reduce safety, while the wrong wheel material may fail when exposed to disinfectants or heavy loads.

At Hengyuan Medical Casters, our engineering team helps OEM manufacturers and healthcare equipment suppliers select the optimal caster configuration for each application. The following guide explains the most important factors to consider when choosing a medical caster wheel.

1. Choose the Correct Load Capacity

The first step is determining how much weight each caster must support.

Calculate Total Load:

• Equipment weight

• Patient weight (if applicable)

• Accessories and attached devices

• Safety margin

Example:

For a four-caster bed:

320 kg ÷ 4 = 80 kg per caster

However, weight is rarely distributed perfectly evenly. We recommend adding at least 30–50% safety margin.

Recommended caster capacity: 120 kg or higher per caster.

Typical Load Capacity Guide

2. Select the Right Wheel Diameter

Wheel diameter has a major influence on mobility.

General Rule:

Larger diameters reduce rolling resistance and cross thresholds more smoothly.
