Company information
Recently, there has been a growing trend among companies to adopt cost-effective Chinese-made bearings, and the evaluation of their quality is also improving. However, concerns have not been completely alleviated. At KMT, we provide a detailed explanation of the realities of Chinese-made bearings and the differences from domestically produced bearings. Based on this, we confirm the quality and application requirements of our customers and make proposals accordingly. Over the past several years, we have visited more than 50 Chinese bearing manufacturers and conducted our own research on quality. As a result, we have carefully selected Chinese companies with stable quality and only manufacture OEM products of the most common and widely used deep groove ball bearings, which we sell under the KMT brand in Japan. While manufacturing takes place in China, quality control and branding are managed in Japan. We are committed to thorough quality management to deliver stable quality. ■ Machinery Business: Handling products that meet the needs of production sites and factory operations. ■ KMT Brand Business: Selling bearing units and other products under the KMT brand. ■ Machining Business: Providing integrated management from procurement of general materials and commercial products to drawing management, processing, and delivery. ■ Overseas Business: Offering timing pulleys, sprockets, gears, shafts, and pressed products that have undergone strict product inspection at our 100% wholly-owned subsidiary in China.
