NSK RA Series Roller Guides (machine tools)

NSK RA Series Roller Guides (machine tools)

NSK RA Series roller guides use rollers instead of balls to deliver very high rigidity and load capacity for machine tools. Sizes 15 to 65 with high-load and super-high-load roller slides.

Key features

  • Roller rolling elements for very high rigidity and load capacity
  • Designed for machining centres and other machine tools
  • Load ratings in compliance with ISO 14728 (100 km basis)
  • Flanged and square roller slides, high-load and super-high-load types
  • Rail cover, double seal, protector and NSK K1 available
