ROBUST Series of Ultra high-Speed / Low Noise ACBB
NSK's ROBUST Series of Ultra high-Speed / Low Noise 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.
Product Features
- ROBUST design: NSK’s optimised geometry; SHX steel material optional.
- Rolling element material can be steel or ceramic.
- Lightweight, high strength Phenolic (T/TR) or PEEK (TYN) cage options.
- Spinshot™II lubrication system for ultra high speed. Grease lubrication for low noise.
Product Benefits
- T / TR (Phenolic) cage
Lower temperature rise compared to conventional precision bearings.
20% faster than conventional precision bearing, up to 80% faster using SHX material.
Temperature robustness: durable under fluctuating temperature conditions.
SHX bearing steel: Improves seizure & wear resistance. Improves fatigue life (4 x conventional bearing steel).
Ultra high-speed with position preload & reduced air noise using Spinshot™II lubrication system (2.5 Million dmn).
Air / Oil systems (3 to 4 dB quieter). - TYN (PEEK) cage
Grease lubrication, with larger internal cage. Special design offers lower friction & noise.
Shorter running-in procedure compared to Phenolic cage.
