Braked castors made using a fabricated steel castor bracket, fitted with a special Injection polyurethane on nylon core fitted with 2 precision ball bearings. These heavy duty braked casters range from 125mm-200mm and have a capacity up to 600 Kg per caster. Our special design PXBJ design centre core was constructed out of necessity to help overcome a issue which most nylon centred wheels experienced when subjected to challenging environments ie abusive or misuse. Polyurethane on nylon centres are quiet ,provide soft cushioned ride and are unlikely to damage floors. Typical applications for our PXBJ are food and pharmaceutical where duty and aesthetics are a consideration . Ball bearing Injection polyurethane was once considered expensive which deterred many from using. Our aim has to always offer value for money our polyurethane is now become much more popular and the cost have come down.
