説明

3″ 4i” 5″ Professional Medical-Grade Swivel & Total Brake Casters Wheels for Hospital Beds

Precision Engineering for Smooth, Silent, and Stable Mobility.

Our RDSD series represents the gold standard in medical and industrial mobility. Designed with high-strength engineering nylon and wear-resistant TPU/PP materials, these twin-wheel casters provide superior stability and a “zero-noise” driving experience. Whether for high-end medical equipment, laboratory furniture, or mobile robotics, the RDSD series ensures safety and durability.

Key Features
Dual-Brake System: One-touch “Total Brake” locks both the wheel rotation and the swivel direction simultaneously.
Silent Operation: Precision double-ball bearings and soft-tread materials eliminate floor vibration and noise.
Industrial Durability: Compliant with EN12531 standards, offering high impact resistance and a wide temperature range (-30°C to +80°C).
Corrosion Resistance: Built with anti-rust materials, perfect for environments requiring frequent sterilization or washdowns.

Frequently Asked Questions (FAQ)

1. Are these casters compliant with international medical standards?
Yes. Our RDSD series casters are manufactured and tested according to the EN12531 standard. This ensures they meet the rigorous safety and durability requirements for hospital bed casters

and medical equipment furniture.

2. What is the difference between “Swivel” and “Total Brake”?
Swivel: Allows the caster to rotate 360 degrees for multi-directional movement.
Total Brake: Our casters feature a dual-action locking mechanism. Engaging the brake pedal locks both the wheel rotation and the swivel direction simultaneously, ensuring the equipment remains completely stationary.

3. What materials are used for the wheels? Will they mark my floors?
The wheel cores are made of high-quality PP/Nylon, and the treads are engineered for silent driving. These materials are non-marking and floor-friendly, making them ideal for hardwood, tile, and epoxy-coated hospital floors.

4. Do you provide 3D CAD or STP files for engineering integration?
Absolutely. We support B2B industrial clients and robotics developers by providing technical documentation. Please contact our support team with your specific model number (e.g., RDSD-100B), and we will send the STP/CAD files for your design phase.

5. What are the temperature limits for these wheels?
The RDSD series is designed to operate reliably in environments ranging from -30°C to +80°C. This makes them suitable for various clinical environments, including cold storage or high-temperature sterilization areas.

6. Can I use these for mobile robotics or AGVs?
Yes. Due to their high dynamic load capacity (up to 100KG per wheel for the 5-inch model) and precision double bearings, these casters are a popular choice for AMR (Autonomous Mobile

Robots) and industrial mobility projects.

 7. Do you support international shipping and customs clearance?
We ship globally to North America, Europe, and Japan. For specialized components, we provide all necessary documentation to assist with customs. If you are ordering for specific projects (e.g., in Spain or the EU), please let us know to optimize the shipping timeline and tax compliance.
