Low Gravity Casters: The “Movable Base” is Steady as a Rock

1. What is a low-gravity castor
The low-gravity caster lowers the relative height between the wheel frame and the wheel axis, shifting the load’s center of gravity downward to create a “ground-hugging flight” mechanical structure. It is often paired with features such as a widened wheel surface, high-elasticity tire body, and fully enclosed dustproof bearings, enabling flexible steering even in a state of extremely low center of gravity.
2. Three Core Advantages
1). Stability: The center of gravity lowers by over 30%, the critical angle for tipping increases 2-3 times, and even high-speed pushing and pulling can achieve “zero sway sensation.”.
2). Province: Under the same load, the contact area of the wheel increases, reducing pressure by 25%. Simultaneously, both ground and tire wear decrease, extending the average lifespan by 1.8 times.
3). Wide: Single-wheel static load 80 kg to 1.2 t, full coverage, oil-resistant, acid and alkali-resistant, anti-static, high-temperature resistant (customizable), with corresponding models available for environments ranging from -40°C to 280°C.
3. Typical Application Scenarios
Industry: Intelligent Warehouse AGV, Electric Reach Truck, Mold Handling Trolley – Continuous 24-Hour Operation Without Breakdowns.
Healthcare: ICU Monitoring Beds, Imaging Equipment Mobile Stands – Promote Quiet Operation (<40 dB), Avoid Disturbing Patients in Corridors.
Business: Supermarket “Silent Cart” and Airport Luggage Cart – Can Be Pushed with One Hand Even When Fully Loaded with 300 kg, Featuring “Zero Inertia” Steering.
High-end equipment: Photovoltaic panel cleaning robot, stage lighting truss—stable as a rail on rough outdoor terrain, with positioning accuracy of ±1 mm.

5. One-sentence summary
When “stability” becomes a productive force, low-profile casters act like an “invisible track” for equipment, ensuring every movement is safe, quiet, and cost-effective.
