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.
