  • produced by high precious technology
  • The wheel hub, molded by cold compressing steel plates ,is light to carry and has stable quality. The holes are punched by 5-axis machining center after cold compression molding, which ensures the final accuracy of the wheel hub.
  • small clearance in axial direction of driven wheel
  • Using manufacturing technology with high precision and operating compensation process for the clearance during the final assembly process maintains the clearance in axial direction of driven wheel in small range .
  • Multi-subdivision design
  • Even if the frame is not precise , the multi-subdivision of the circumference can make it stably operate .Avoiding the drawback of up and down vibration from usual omni wheel .
  • 2 bearings embedded in every driven wheel
  • 2 miniature bearings are embedded in every driven wheel , changing the sliding friction on driven wheel into rolling friction, smoothly the lateral movement , and truly realizing micro-resistance in lateral movement of omni wheel .
  • high quality rubber
  • The driven wheel adopts high-quality rubber , accompany with drum-shape and appropriate hardness.The Ql series omni wheel shows strong grip ability and almost silent in the process of measuring and testing on wood , tile, carpet and so on.
  • nickel-plated on the hub surface
  • nickel-plated on the hub surface , attractive and durable.
  • Continuous improving QMA series omni wheel
  • steady improvement is the traits of Hangfa product, it can ensure the customers get the best products and service .
