NSK  is a manufacturer of bearings globally and the largest in Japan. The company produces industrial machinery bearings, precision machinery and parts, and automotive bearings and components.NSK Bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts.

NSK Bearing extend the working life of wheels, pulleys, and other rotating parts by reducing friction and enabling parts to move smoothly. Also called slewing rings or slewing bearings, they are installed between KOYO bm2817 Bearing two surfaces to keep parts aligned and support axial and radial loads. Axial (thrust) bearings support loads parallel to the axis of the shaft, such as those exerted by a table supporting a weight.
