Secure Twin-Wheel casters (also known as dual wheel casters, double wheel casters, twin wheel swivel casters) feature durable nylon (PA6) construction, high load capacity, ultra-low noise, and smooth rolling that resists hair and dust.
Advanced dual-pedal locking (directional + full brake) ensures easy control and firm immobilization. Widely used on: hospital patient beds, emergency carts, medical equipment trolleys, medicine distribution carts, infusion pump trolleys, instrument carts and rehabilitation trolleys. They enhance medical equipment movement stability and efficiency, improving experiences for staff and patients.
A twin wheel caster features two wheels side by side on a single bracket, providing higher load capacity, better stability, and smooth rolling. It distributes weight evenly, protects floors, and moves easily over thresholds or uneven surfaces. Ideal for medical equipment, hospital beds, carts, and industrial trolleys, twin wheel casters offer quiet, durable, and reliable mobility, with optional brakes or swivel features for added safety and control.
One advantage of Twin Wheel Caster is that it can carry much more weight . Additionally, you can use a smaller wheel diameter to keep the overall height lower if needed. The dual wheel design also makes it easier to move the equipment, as it takes less force to get a dual wheel swivel caster to change directions. This can improve ergonomics and reduce the risk of injury. Twin Wheel Casters also tend to have a longer life because they are designed specifically for carrying heavier loads. An additional advantage is suitable for applications where it’s crucial to prevent floor damage. a dual wheel caster can use polyurethane tires, which are gentler on the floor. In fact, two poly wheels on a dual wheel caster can often carry the same load as a single wheel caster with a forged steel wheel.
Simply remove your single wheel and tire, and mount the conversion hub in its place. This hub provides the proper spacing and converts your vehicle from a stud piloted to a hub piloted mounting for dual wheels.
