Company profile
YUAN JING PRECISION CO., LTD. (YJP) is a Taiwan-based engineering and manufacturing partner specializing in customized bearing and precision motion solutions for semiconductor equipment. YJP supports applications requiring high positioning accuracy, rigidity, compact design, load performance, cleanroom and vacuum compatibility, corrosion resistance, low-lubrication concepts, and stable long-term operation. Its bearing capabilities include application-based bearing design, selection and optimization, cross-roller bearings, ultra-thin bearings, large-diameter bearings, precision-machined rollers, surface-coating options, and integration with customers’ mechanical systems. In-house OEM precision machining and grinding enable YJP to manufacture bearing rings, housings, mating structures, and other critical mechanical components, with geometric tolerances down to 0.002 mm and components up to Ø2,500 mm depending on geometry, material, and process requirements. Quality control uses disciplined inspection procedures and ZEISS CMM measurement, and YJP combines bearing engineering, high-precision component manufacturing, and system integration for semiconductor-equipment applications where standard catalog products are insufficient. YUAN JING PRECISION CO., LTD. was established in July 2005 and provides turning, milling, grinding, OEM, measurement, drawing, and CAD data services in 3D and 2D. Its experience spans processing machinery, bicycles, automobile and motorcycle parts, pneumatic and electric tools, pneumatic and hydraulic parts, mold parts, and aerospace parts, with technology also applied across industry and academia. Partnered processes include gun drilling, keyways, gear cutting, electrical discharge machining, polishing, laser processing, welding, heat treatment, electroplating, and black oxide treatment. YUAN JING PRECISION CO., LTD. follows ISO 9001:2015 and ISO14001:2015 standards and uses Japanese processing equipment, Zeiss 3D coordinate measuring stations, and trained engineers; its stated 0.002mm minimum-tolerance capability has generated hundreds of domestic and international inquiries. The company also works with partnered factories for heat treatment, coating, die casting, welding, laser cutting, and other processes as a one-stop service intended to shorten project delivery time. It has extended manufacturing services to large-dimension mechanical components for customers in mining and construction machinery, and it states that customer technical drawings and related data are strictly protected with an NDA signed in advance.
