Application Scenarios

These high-performance casters are engineered for environments demanding stability, hygiene, and silent operation:

High-End Medical Equipment: Ideal for manual or electric hospital beds, operating tables, and mobile X-ray machines, providing smooth movement and reliable locking.
Laboratory & Scientific Instrumentation: In precision-sensitive labs, the TPU tread absorbs micro-vibrations to protect sensitive testing equipment.
Heavy-Duty Service Robots: With a dynamic load capacity of up to 160kg and a 200mm diameter, these are perfect for light AGVs, delivery robots, and disinfection robots.
Aged Care & Rehabilitation Devices: Provides a silent and effortless steering experience for power wheelchairs or specialized nursing beds, compliant with EN12531 standards.
Cleanrooms & Pharmaceutical Workshops: The corrosion-resistant aluminum alloy bracket and temperature range of -30°C to +80°C adapt to frequent cleaning and various controlled environments.
 

FAQ

Q: What are the advantages of TPU treads compared to standard rubber wheels?
A: The TPU (Thermoplastic Polyurethane) tread offers superior wear resistance and elasticity. It ensures silent operation and, crucially for hospital environments, does not leave black marks on expensive flooring.

Q: What is the difference between “3-position” and “2-position” gear options?
A: 3-position gears offer directional lock (for straight-line tracking), total lock (full immobilization), and free swivel (360° movement). 2-position gears typically include only total lock and free swivel modes, depending on your central linkage design.

Q: How do I choose between the Long Stem (96mm) and Short Stem (50mm)?
A: The Short Stem (50mm) is usually for standard mounting or height-restricted equipment. The Long Stem (96mm) is specifically designed to interface with the central locking rods of medical beds through integrated holes in the stem.

Q: What certifications do these casters hold?
A: This series is fully compliant with the EN12531 standard for medical casters. The high-density aluminum alloy bracket and precision ball bearings ensure a balanced and stable structure under full load.

Q: Do you support bulk purchasing or customized specifications?
A: Yes, as an industrial hardware specialist, we support B2B bulk orders. We can provide customized solutions if you require specific stem diameters (e.g., 28mm or 32mm) or specific locking angles (30°/45°).
