LYZYC Ultra-long Life and Ultra-high Speed Ceramic Angular Contact Ball Bearing
XCRS719 Seriess, XCRS70 Series, HKSV Series

Structural features:
 1. With small ball design and modified internal structure, this LYZYC Series bearing features ultra-long life and ultra-high speed.
 2. This ultra-long-life ball bearing is mainly designed for the works that require high rotational speed and high load.
 3. The material of outer ring is made of X-life Cronidur30 high nitrogen stainless steel with special heat and cold treatment processes.
 4. Rolling elements are high-performance hot isostatically pressed ceramic balls, so the service life of these bearings are increased by 10 times compared to which of standard bearings in the case of mixed friction.
 5. With a contact angle of 18°, this bearing can carry axial load and radial load either alone or in combination.
 6. Ball bearing cages (or retainers) adopt outer ring guided fabric reinforced phenolic resin cages, outer ring guided PEEK cages, and inner ring guided silver-plated steel cages.
 7. Phenolic resin cage is the standard cage that can maintain a stable long-term work under 80°С.
 8. Under the ultra-high speed and special work conditions, you may select PEEK cage for a stable long-term work under 220°С.
 9. Using inner ring guided silver-plated steel cage or without cage, is suitable for a stable long-term work under 450°С.

Speed factor:
         Grease lubrication DmN≤2100000, limiting rotational speed N≤2100000/Dm, Dm= bearing mean diameter
           Oil lubrication (with a minimum amount) DmN≤3200000

Applications:
LYZYC Series ceramic angular contact ball bearing is mainly used in working conditions require long-life, high rotational speed and high precision bearings, such as imported CNC machining center spindle, ultra-high speed spindle for grinding, ultra-high speed ultracentrifuge, turbojet engine shaft, turbocharger and so on.
Sealed bearings with pre-packed grease are also available.
