NSK's ROBUST Series of Ultra High-Speed Angular Contact Ball Bearings for machine tool main spindles 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 while reducing energy costs.
- Durability under fluctuating conditions: Lower temperature rise & improved thermal robustness compared to conventional super precision bearings
- 20% faster than conventional super precision bearing, up to 80% faster using SHX material
- SHX bearing steel: Improves seizure & wear resistance. Improves fatigue life (4 x conventional bearing steel). Improves grease life time
- Reduced air noise using bearings with Spinshot™II oil ail lubrication system (3 to 4 dB quieter)
- Ultra high-speed possible with position preload (2.5 Million d m n)
- Sealed types for easy & safe handling and improved grease life
- Grease lubrication, with larger internal space
- Special design offers lower friction and avoids typical noise from phenolic cage
- Shorter run-in procedure compared to bearings with phenolic cage
- BearingsTYN cage improves grease life
- PEEK cage is available for applications over 2.5 Million d m n
