Zusammenfassung:The invention relates to sewing machine fittings and concretely relates to a wear-resistant inner shuttle of a rotating shuttle. The wear-resistant inner shuttle comprises, by weight, 0.1-0.3% of C, 0.1-0.4% of Si, 0.3-0.9% of Mn, 0.7-1.30% of Cr, 0.10-0.3% of Mo and the balance Fe. The wear-resistant inner shuttle of a rotating shuttle is prepared by an injection molding method, greatly improves product performances by a proper temperature and a proper distribution ratio, especially improves product wear resistance, has a low production cost and can be operated simply.
