Overview
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. Our 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 the customer’s mechanical system. YJP’s bearing solutions are strengthened by in-house OEM precision machining and grinding capabilities, enabling us to manufacture bearing rings, housings, mating structures, and other critical mechanical components. Depending on part geometry, material, and process requirements, YJP can achieve geometric tolerances down to 0.002 mm and machine components up to Ø2,500 mm. Quality control is supported by disciplined inspection procedures and ZEISS CMM measurement. From bearing engineering to high-precision component manufacturing and system integration, YJP helps semiconductor equipment manufacturers develop reliable solutions where standard catalog products are insufficient.
