At the beginning of the 1960s, we began globalizing operations while exploiting technological prowess garnered from the production and development of bearings to launch forays into the fi elds of automotive products and precision machinery and parts. The centerpiece of our Mission Statement, MOTION & CONTROL, encapsulates a com- mitment to providing products that control friction and curb energy loss, in order to assist global environmental protection while contributing to industrial growth and the conve- nience and safety of everyday life. the assessment Of Outside agencies Social responsibility indexes (SRIs) include companies that promise long-term sustainable growth because they merit high evaluations for environmental and social contributions as well fi nancial standing. Moreover, a broad range of institutional investors are attaching greater importance to such companies. Four internationally recognized SRIs include NSK as of March 2011.

Bear- ings reduce friction generated in rotating parts, which lessens abrasion and extends machine service life. Longer-lasting machinery also helps to save resources. ◎pOint3: reliability Friction is always accompanied by heat. Excessive frictional heat causes the sliding surfaces of machinery to seize up. By reducing the frictional heat, bearings prevent seizure and help machinery achieve a greater degree of reliability and help prevent malfunctions.

As a result, competition has developed in increasingly borderless business conditions. NSK began developing over- seas business bases in earnest from the early 1960s. Since then, we have taken advantage of our technological capabilities to build a global network that caters to diverse demand around the world. Going forward, we intend to boost our presence in overseas markets even further. u.k. u.s.a.
