TANRAY KOGYO Co., Ltd.
We produce forged ring products that realize reduced input weight and time required for turning.
We offer integrated production of forged ring products (outside diameter 100 to 1000). We cover processes from forging to turning. Our company has realized productization using various kinds of steel such as bearing steel, steel for machine structural use, stainless steel, etc. Our rolling mill development has made it possible to plan a reduction of the machining allowance and differentiation of forged products. Our efforts have reduced both input weight and the time required for turning during later processes.
[Company strength] We supply all the major bearing makers in Japan. We deliver some of our bearings in the form of finished products. In addition, we have successfully reduced product transport times within the plant, the customer’s management time, and the lead-time to delivery through our integrated production system. This has been favorably received by our customers. Our ring products can be anywhere between outside diameter 100 to 1000, which allows us to provide a wide variety of ring products. [Business description] Our company has an integrated production system for finishing forging, turning, hardening, tempering, grinding, and assembly in-house. We deal with bearing steel, steel for machine structural use, stainless steel, heat-resistant steel, super alloy steel, tool steel, and other kinds of specialized steel. [Industry] Ring product manufacturing [Strength of products/technologies] Through the design and construction of automated ring forging lines, and our own company’s rolling mill development, we have realized machining allowance reduction and differentiation of forging products. This has resulted in a reduction of input weight and the time required for turning during later processes of production. We have a production control system for central management from receiving orders to shipment (delivery). It allows for process management, cost management, and cost reduction. [Representative's message] We have expanded our business areas since the business succession in 2003 to include heat treatment and turning, hardening and tempering, polishing, and assembly. This is in addition to our previous forging. At the same time we have been developing our own technologies such as our rolling mill and dinking machine. As a result, we have received favorable responses from our customers in terms of quality, cost, and lead-time. This has resulted in increased sales orders. In the future, we will focus on further improving QCD. We will also proceed with new businesses and overseas expansion. [Company structure for market development/overseas expansion] The sales department has a dedicated sales team for potential new customers. This team responds to all inquiries from major companies and overseas companies. Our staff in the production control department respond to technical inquires. They sometimes visit the customer’s site if necessary. Responses to new customers are always overseen by the President. Overseas deals are conducted faithfully, including the collection and management of information. [Market share/Ranking] 80% of the bearing market (?100 to ?300) for large industrial machines manufactured in Japan. 100% of the retaining ring market for railway motors. [Awards and media coverage] [Awards] [Media] [Authorization/Certification] ISO 9001 and 14001 certification; Strategic Core Technology Advancement Program certification (2013). [Joint research and development] In 2013 our company was selected by METI for a Strategic Core Technology Advancement Program project. We have been conducting joint development with the Public Interest Incorporated Foundation Niigata City Industrial Promotion Center and Industrial Research Institute of Niigata (2013 to 2015). [Transaction terms] Based on our terms and conditions.
