Selecting the correct caster wheel size is one of the most important decisions when designing or upgrading mobile equipment. Wheel diameter directly affects load capacity, rolling resistance, maneuverability, and floor protection. This page is designed to help both new and existing customers quickly identify the right caster wheels by size, ensuring optimal performance for their specific application.
At Zambus, caster wheels are engineered for precision, durability, and real-world use across industrial, commercial, medical, and furniture environments. Whether you are building compact equipment that requires tight turning radii or heavy-duty carts that must roll smoothly under substantial loads, choosing the appropriate wheel diameter is essential.
Smaller caster wheels, typically under 2 inches, are ideal for lightweight furniture, electronics enclosures, and compact assemblies with limited space. Mid-range sizes from 2 to 4 inches offer an excellent balance of stability and maneuverability, making them well-suited for workstations, carts, and general-purpose equipment. Larger caster wheels, ranging from 4 inches to over 5 inches, are designed for heavier loads, uneven surfaces, and applications where smoother rolling and reduced effort are critical.
This wheel size guide organizes Zambus caster wheels into clearly defined size categories, allowing you to quickly narrow down options based on diameter. Each size range includes compatible leveling casters, non-leveling casters, medical plastic casters, and replacement wheels and parts. By starting with wheel size, you can confidently move forward knowing your caster selection supports both performance requirements and long-term reliability.
