The first spherical roller bearings with metallic shields are proposed in the KIZEI® bearing range.  This innovative solution created by NTN-SNR is easy to use and offers production output and equipment reliability optimisation, while reducing maintenance costs.

KIZEI®, the viable alternative for dirty environments


Advantages offered by KIZEI®

  • Protection against external solid contamination thanks to metallic shields

  • Improved lubrication due to better grease retention inside the bearing

  • Longer bearing life time compared to standard open bearing

  • ISO dimensions – 100% interchangeable with standard open bearing


Premium characteristics

  • ULTAGE load ratings and speeds

  • Nitrided steel cage and shields for better shock resistance

  • Wide working temperature range (-40°C up to +200°C)

  • Initial lubrication process similar to open spherical roller bearing (bearing delivered without grease) – Reduced in service lubrication frequency

  • Similar misalignment to open spherical roller bearing – Possible internal inspection to facilitate maintenance

  • Mounting elements and procedures are identical to that of a standard bearing – For tapered bore, internal clearance checking is possible after mounting.

Reduced Maintenance Costs
