Always adhere to the responsibility of revitalizing national industry and achieve industrial service to the country through innovation.

Nine Star's main products include deep groove ball bearings, electrically insulated bearings, and hybrid ceramic bearings. The insulated bearings were successfully produced and put into the market by Nine Star in 2010, breaking the monopoly of the foreign insulated bearing market and ending the era of fully imported insulated bearings. Nine Star can produce insulated bearings with inner diameters ranging from 30mm to 300mm, as well as insulated bearings derived from the entire range. Conventional insulated bearings are available in stock. The customer return rate of Nine Star's insulated bearing products continues to increase, and we have established long-term stable cooperative relationships with multiple bearing retailers and agents, successfully supporting multiple motor manufacturing enterprises.

All along, the Nine Star team has always adhered to the principle of "customer first, quality oriented, and all employees value excellence", strictly controlling every aspect of production and producing every Nine Star insulated bearing that can add value to customers.
