NSKROBUST Ultra High-Speed Cylindrical Roller Bearings

When machining speed is a priority, NSKROBUST series bearings cylindrical roller bearings deliver superior ultra high-speed performance with high rigidity and stability with low heat generation. Advanced material options for rings and rollers offer greater heat and seizure resistance and extended bearing fatigue life.

NSKROBUST Ultra High-Speed Cylindrical Roller Bearings

Design Features

  • N-type single row cylindrical roller bearing with inner ring rib
  • Optimized internal design delivers utmost bearing fatigue life
  • Inner / outer rings and rollers available in standard SUJ2 bearing steel or advanced heat-resistant SHX steel
  • Special design outer ring guided PEEK resin cage
  • Low heat generation N10-Z types available
  • With cylindrical and tapered bores
  • Radial internal clearances CC1 for cylindrical bore, CC0 for tapered bore
  • With P2, P4, P5 and P4Y accuracy
  • For dimension series 10
  • For shaft diameters ranging from 45 to 85 mm

Operating Benefits

  • High-speed performance - twice that of conventional roller bearings
  • Heat resistant and highly rigid PEEK resin cage provides stable rolling movement under high-speed operating conditions
  • SHX steel rings and rollers deliver longer fatigue life (4 times) and support higher limiting speeds
  • Low heat generation enables longer lubricant life - outer ring temperature rise is 30% lower than conventional bearings
