Tungsten Carbide Transferring Ball

Tungsten carbide transferring ball, as the name suggests that it is a kind of flexible sphere can run in all directions. So it also has been called universal ball, transferring roller or bull’s eye, etc. Due to the flexibility universal ball rolling, the work bench or other original material quality or bulky workpiece can be more portable to slip, which also greatly reduces the labor intensity of the operator. Universal ball is suitable for transporting the items with smooth and strong surface of bottom, such as cardboard boxes, plastic crates, pallet parts, and surface roughness of the steel sheet-like object. In addition, according to different load requirements, it can adjust the density distribution of transferring ball, or can choose transferring ball with different materials and carrying capacity.

Commonly transferring ball materials includes steel ball, stainless steel ball, carbon steel ball, bearing steel ball, galvanized steel ball, plastic steel ball, tungsten carbide ball and so on. By comparison, tungsten carbide transferring ball has the better properties among them. Tungsten carbide is composed of WC and Co, WC has higher hardness and Co added improves the toughness, strength and wear resistance. It by carbide ball and the support base with the completion of transfer of the workpiece. Tungsten carbide transferring ball has higher machining accuracy and the surface without secondary treatment.

The surface toughness of common steel ball can not meet the requirements, which electrically galvanized or chrome effect will be affected. And secondary processing if the grinder be polished, dimensional accuracy will be affected to some degree. Except surface quality, there are several evaluation parameters of universal ball overall quality, such as flexibility, noise and dimensional accuracy. Generally, plate with your fingers on the ball was moving moment of inertia of the ball more than three seconds for qualified. The noise is related with ball accuracy and the quality, tungsten carbide ball has higher accuracy and quality so its noise is lower and the rotation is smoother and more uniform.
