NTools TPR Caster and TPR Caster B is a rotary transport wheel-set mounted using M10 screw. The use of two ball bearings (radial and thrust) and a robust steel frame enable free rotation of the wheel and manoeuvring without using extra force. Consequently, this improves directional stability of the set. A rubber lining of wheels, i.e. tread, is made of TPR material - thermoplastic rubber. The material reduces any noise generated during rolling to a minimum while leaving no traces on the surface. NTools TPR Caster B is additionally equipped with a brake used to immobilize the wheel from moving freely.
