Quality Board Meeting

To strengthen Group-wide initiatives NSK Group management checks the status of quality control and directs the needed initiatives in a topdown manner at the Quality Board Meeting, which is chaired by the president and composed of directors in charge of each business division headquarters. NSK has also established quality committees in each business division headquarters and is working to strengthen quality improvement efforts through cooperation among the manufacturing, sales, and design departments.

Global Quality Assurance Organization

The NSK Group has established quality assurance departments in Europe, the Americas, China, and ASEAN as well as quality assurance departments in other areas. This has reinforced the Group's global quality assurance organization by providing support tailored to the needs of customers in each country and region. In the event of a problem with a product or service, information can be provided quickly to customers. The relevant departments are brought together, and take swift and appropriate countermeasures to prevent the problem from spreading. The causes are promptly investigated and measures are taken to prevent reoccurrence.
