BKZ Industry was founded in Shandong in May 2011. It mainly manufactures insert bearings, mounted bearing units, and bearing housings, while also producing deep groove ball bearings, self-aligning ball bearings, tapered roller bearings, cylindrical roller bearings, spherical roller bearings, and other types. To expand its production capacity, BKZ Industry established a new factory in Jiangsu, which now manufactures deep groove ball bearings and other ball and roller bearings.

We understand that consistent quality matters to every buyer. That is why we conduct strict inspections from raw materials through every stage of production and provide traceable quality records for every order.
BKZ Industry is more than a bearing manufacturer and supplier. We understand the challenges distributors, wholesalers, industrial suppliers, and manufacturers face when sourcing bearings in bulk—and provide practical solutions to simplify procurement and reduce risks.
Unlike single-factory suppliers producing only one or two bearing types, BKZ Industry operates two factories manufacturing seven major bearing categories, with further expansion planned.
Beyond in-house manufacturing, BKZ Industry works with 20+ partner factories to supply additional bearings and mechanical parts—all from one supplier.
BKZ Industry is ISO 9001 certified, with additional certifications available for specific applications. All products undergo documented, traceable inspections to ensure consistent quality.
With over 15 years of experience, BKZ Industry understands bearing requirements, quality standards, export documentation, and delivery processes, helping customers reduce sourcing risks and avoid costly mistakes.
BKZ Industry supplies bearings in standard ISO dimensions or dimensions interchangeable with other brands. Custom bearings can also be manufactured based on your drawings or application requirements.
Whether manufactured in-house or sourced from our partners, all bearings and mechanical parts support OEM and customization based on customer requirements.
Provide the bearing number, drawing, sample, or operating conditions, and BKZ Industry will help select the correct product to reduce selection errors.
In-house manufacturing, long-term factory partnerships, and consolidated purchasing enable BKZ Industry to reduce sourcing costs and offer competitive prices without compromising quality.
BKZ Industry bearings deliver reliable performance across industries worldwide—including transportation, energy, and industrial machinery—with precision and long-lasting durability.
