NTN KIZEI spherical roller bearings

KIZEI® – innovative spherical roller bearings with metallic shields. These bearings designed by NTN-SNR offers production output and equipment reliability optimisation, while reducing maintenance costs.

• Nitrided steel cage and shields for better shock resistance
• Better protection against external solid contamination thanks to metallic shields
• Load ratings and speeds are similiar to ULTAGE series
• Working temperature range -40°C to +200°C
• Improved lubrication due to better grease retention inside the bearing
• Longer bearing life time
• ISO dimensions – 100% interchangeable with standard open bearing
• Initial lubrication* process similar to open spherical roller bearing, but required 3 times less relubrications

^{*KIZEI is supplied without grease}

Mounting tools are identicalto that of a standard bearing. Similar misalignment to open spherical roller bearing allows internal inspection to facilitate maintenance. For tapered bore, internal clearance checking is possible after mounting.
