Material: PP (Polypropylene) As the core material of the casters, PP offers multiple advantages tailored to wheelchair scenarios:
Wear-Resistant & Durable: PP material has moderate hardness and excellent wear resistance, capable of withstanding common surfaces such as indoor floors (tiles, wooden floors, concrete floors) and non-slip mats in rehabilitation institutions. It reduces wheel wear after long-term use and extends the replacement cycle.
Lightweight & Portable: Compared to metal or rubber materials, PP wheels are lighter, avoiding additional forward load on the wheelchair and ensuring ease of pushing.
Corrosion-Resistant & Easy to Clean: PP material is not easily eroded by water stains or disinfectants (e.g., medical alcohol, chlorine-containing disinfectants). Daily cleaning only requires wiping, making it suitable for the hygiene and cleaning requirements of medical scenarios.
Quiet & Shock-Absorbing: The wheel itself has a certain elasticity, which reduces collision noise with the ground during movement and alleviates slight bumps, enhancing the rider’s comfort.
Size Specifications: Multiple Inch Options (5/6/8/10 Inches)
Four common sizes are available to fit different types and usage needs of wheelchairs. The selection logic is as follows:
5 Inches / 6 Inches: More suitable for small, portable wheelchairs (e.g., foldable wheelchairs). The compact wheel size facilitates wheelchair folding and storage, making it ideal for short-distance home movement or outdoor carrying.
8 Inches / 10 Inches: Compatible with medium and large wheelchairs (e.g., care-type wheelchairs, front casters for electric wheelchairs). The larger wheel diameter provides stronger passability, allowing the wheelchair to navigate slightly raised surfaces (e.g., thresholds, carpet edges) and making it suitable for long-term outdoor use or rehabilitation training scenarios.
