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 and improved grease life

  • ROBUST Series with TYN (Polyamid) cage

    - 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

  • ROBUST Series with T42 (PEEK) cage

    - PEEK cage is available for applications over 2.5 Million d m n
