From miniature ball bearings no larger than the head of a match to giant slewing ring bearings with outside diameters in excess of 16 feet, NSK products are designed for high accuracy, rugged dependability, and minimum maintenance. From bearings for aircraft engines and machine tools, to “sealed-clean” bearings for automobiles and rolling mills, to bearings for computers and home appliances, NSK delivers quality the world over.
Sales of ballscrew actuators in numerous applications are growing dramatically; therefore, NSK standardized certain popular types and sizes in order to streamline their production. Three results of this for their users are low cost, faster deliveries, and improved accuracy. Standardization requires that the shaft's ends all be uniform; therefore each customer can provide the means for mounting and driving them. However, special NSK ballscrew support bearing units are available to simplify this task. Though standardization limits the scope of types, sizes, and other specifications offered, the units available in NSK's LPR/PR- and R-Series can accommodate many applications. therefore, they should be seriously considered any time a precision linear actuator is required.
NSK manufactures a full range of miniature ball screw products to meet the challenges of medical and lab automation applications. To ease the pressure of medical equipment designers to develop smaller and smaller work envelopes, our miniature linear guides provide the perfect fit.
As one of the most demanding industries for clean and precise products, NSK has a product offering to meet your needs. From precise, miniature ball screw products to clean room and special coating capabilities, NSK has the products and solutions to meet the wide range of applications in the medical industry.
Since rolling bearings are manufactured with very high precision, noise and torque are minimal. For deep groove ball bearings and cylindrical roller bearings particularly, the noise level is sometimes specified depending on their purpose. For high precision miniature ball bearings, the starting torque is specified. Deep groove ball bearings are recommended for applications in which low noise and torque are required, such as motors and instruments.
