Products Description
These rubber wheels with built-in PU foam cores act as standard rear wheel spare parts for all types of powered wheelchairs. Every wheel assembly adopts a dual-layer composite setup, combining durable outer rubber casing and microcellular polyurethane elastomer filling fully injected into the tyre cavity. To guarantee stable wear resistance and consistent product quality, we only source finished rubber tyres from two trusted mainstream manufacturers: Cheng Shin and Innova. The integrated foam filling eliminates the hidden trouble of air leakage, delivering steady load capacity and smooth rolling performance for daily rehabilitation mobility use.
Shortened as foam insert tyres, this composite wheel unit combines tough rubber outer skin and microcellular PU elastomer inner filling. It boasts outstanding practical strengths including zero air refilling, strong anti-piercing property, stable shock absorption, zero daily upkeep and high travel safety. These wheels are widely fitted on rehab wheelchairs, elderly mobility scooters, baby carriages, service robots, workshop transport trolleys and light athletic gear. Retaining the classic appearance of standard rubber tyres, it fully fixes the common flaws of inflatable tyres such as puncture failures, slow air loss, sudden deflation and recurring routine servicing work.
We adopt rotary casting craft to complete polyurethane foam encapsulation inside rubber tyre shells. Guided by centrifugal force during rotation, foaming materials form differentiated density structures across the tyre interior. The ground-contacting tread layer forms compact solid texture for durable wear resistance, while tyre sidewalls retain soft elastic property. Foam materials spread uniformly across the entire cavity without uneven agglomeration or hollow voids, delivering balanced shock buffer performance. The optimized internal structure greatly offsets road bumps and vibration, offering consistent smooth rolling experience for all mobility equipment users.
