Company information
KONISHI Manufacturing Co., Ltd. has been providing products to the world market with ball bearings under the trademark name "MRK." "Precision machining" and "mass production" are fundamental concepts for the manufacturing industry, yet they are being reexamined in light of the harsh realities that constantly demand speed and cost reduction. In the midst of changing values and diversifying needs, how we can enhance customer satisfaction and trust is a significant challenge and driving force for us. We believe that thorough quality control, improvements in work efficiency, a flexible system that introduces new information and technologies as needed, and above all, a customer-centric mindset will lead to new possibilities. We are actively working on "small lots" and "short delivery times," focusing on building a system that meets current needs and turning customer proposals into reality.
