NTN Rolamentos de rolos cilíndricos de várias carreiras

Contate agora

The cylindrical rollers NTN produces today have an optimized shape in order to limit the overpressures at the ends of the rollers (edge effect). As a result, the overall service life of the bearing is directly increased, even in applications with some misalignment. 

 

NTN’s asymmetrical roller design is commonly used in pairs at the rotor and generator side of the main shaft. By pushing the rollers into the center inner rib, our products allow for quieter, more smoothly running bearings with low heat generation and, ultimately, longer life.
