KIZEI – a protected bearing solution for dirty conditions
NTN/SNR’s new range of protected spherical roller bearings has been developed to meet the toughest challenges in industry: dust, sand and other solid contaminants, which are a significant cause of bearing damage and maintenance costs. It is estimated that solid contaminants account for up to one fifth of all spherical roller bearing failures.

Kizei offers the following benefits for problems in demanding conditions:
• Protection against solid contaminants is improved, as the guards prevent dirt from entering the bearing – Longer service life and lower costs.
• The guards retain the lubricating grease more effectively inside the bearing - Lubrication intervals up to 3 times longer than with open bearings.
• Easy replacement of open spherical roller bearings thanks to ISO dimensions.
• No special tools or accessories required; standard sleeves and nuts can be used.
General features of Kizei bearings:
• Designed and manufactured according to NTN premium class requirements.
• 100% European production.
• Dimensioning according to ISO.
• High-quality steel retainers and guards - Maximized impact resistance and optimized corrosion resistance.
• Wide operating temperature range (-40°C…+200°C).
• Easy lubrication and installation.

The strengths of KIZEI bearings are particularly evident in:
• Cement, mineral and construction industries.
• Conveyor and lifting equipment.
• Environments where solid dirt causes problems for bearing durability.
