High rigidity
   Types SNR / SNS are compact linear motion products based on the design of the LM guide type NR, but with increased block rigidity. Since the radial rigidity, and lateral rigidity were all increased, types SNR / SNS have the highest rigidity in the cages ball series. The two types are available in the same dimensions: type SNR for the radial load type and type SNS for the four way equal load rating type. Either may be selected according to your application.
