NSK's ROBUST Series of Ultra high-Speed Angular Contact Ball Bearings for machine tool main spindles. These bearings offer improved thermal robustness, low heat generation, improved seizure rates and low noise. This ensures that machine tools can operate at ultra-high speeds, increasing manufacturers productivity & reduced energy costs. Industries Machine Tools Product Features ROBUST design - For better durability under fluctuating conditions: Lowest temperature rise & improved thermal robustness SHX bearing steel improves seizure & wear resistance, fatigue life & grease life time Rolling element material can be steel or ceramic Bearing with Spinshot™II oil air lubrication system: ultra high speed & reduced air noise (3 to 4 dB quieter) Benefits ROBUST Series 20% faster than conventional super precision bearing, up to 80% faster Ultra high-speed possible with position preload (2.5 Mil. dm* n) ROBUST Series with Polyamid cage Grease lubrication with larger internal space Lower friction, shorter running-in procedure ROBUST Series with PEEK cage Provides limiting speed over 2.5 Mil. dm* n
