What types of toolbox casters are there?

Toolbox casters come in many types and can be categorized based on various criteria, as follows:

Classification by Steering Performance
Universal casters: The hub and bracket rotate relative to each other, allowing for 360-degree rotation, allowing for flexible toolbox mobility. This makes them suitable for applications requiring frequent changes of direction, such as repositioning a toolbox in a workshop.

Fixed casters: The hub and bracket are fixedly connected, allowing for linear movement only. These casters are suitable for toolboxes requiring stable linear movement, enhancing stability and often used in conjunction with universal casters.

Brake casters: Casters with brakes are based on universal or fixed casters and feature a brake mechanism that locks the caster when needed to prevent the toolbox from sliding. These casters are ideal for applications requiring frequent stops, such as on slopes or when securing a toolbox during work.

Classification by Material
Polyurethane (PU) casters: Highly wear-resistant, weather-resistant, and resilient, they are quiet, floor-friendly, and can withstand heavy loads, making them suitable for a variety of environments, including indoor floors and some outdoor applications.

Nylon wheels: They are wear-resistant, pressure-resistant, and impact-resistant, making them suitable for use on rough surfaces like factory floors. However, they can be noisy when rolling.

Rubber wheels: They offer excellent quietness, anti-slip properties, and shock absorption, protecting floors. They are suitable for use in indoor environments with high noise levels, such as hospitals and schools. However, they are not oil-resistant and have relatively low wear resistance.

Cast iron wheels: They are sturdy and have a high load-bearing capacity, making them suitable for heavy tool boxes. However, they are prone to rust and are generally used in industrial settings.

Classification by Load Capacity:

Lightweight casters: They have a relatively low load-bearing capacity and are suitable for lightweight tool boxes, such as those used in household or small repair shops.

Medium-duty casters: They can handle medium weights and are suitable for general industrial tool boxes or larger household tool boxes.

Heavy-duty casters: They have a higher load-bearing capacity and can be used to carry large and heavy tool boxes, such as those used in factory workshops.
