Unprecedented KIZEI® spherical roller bearings
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.
