Angular Contact Ball Bearings - ROBUST Series of Ultra high-Speed ACBB

Features

• ROBUST design: NSK’s optimised geometry
• SHX steel material optional.
• Rolling element material can be steel or ceramic.
• Lightweight, high strength Phenolic (T), Polyamid (TYN) or PEEK (T42) cage.
• Bearing with Spinshot™II lubrication system for ultra high speed.

Benefits

• ROBUST Series
  - 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, & improved grease life time

• ROBUST Series with TYN (Polyamid) cage
  - Grease lubrication, with larger internal space. 
  - Special design offers lower friction & avoids typical noise from phenolic cage.
  - Shorter running-in procedure compared to bearing with phenolic cage.
  - Bearings in wide series with TYN cage improves grease life time.

• ROBUST Series with T42 (PEEK) cage
  - PEEK cage is available application over 2.5 Million d m n
