The apparent non-scaling of pinning force data in Bi-based high-Tc superconductors was discussed. The pinning forces in Bi-2223 at temperatures between 18 K and 80 K were investigated. It was found that in the intermediate temperature range, the peak position of pinning force scaling shifted towards 0.18 on increasing temperature, manifesting a change in the basic pinning mechanism. The results suggested that the pinning force scaling of 0.33 must be maintained in further development of the Bi-2223 superconductors.
