Reinforced design with cylindrical roller bearing (For excessive radial forces)

Reinforced design with cylindrical roller bearings is recommended for applications like belt and pulley drives where external radial forces may be greater than stipulated at catalogs. In case the external radial force subjected to the bearing of motors having reinforced design with cylindrical roller
bearing (NU series) is too small during operation, slippage occurs between the rollers and raceways which may result in smearing. Please consult us if radial force is very small or strong shock loads or vibration are expected as special bearing arrangements may be required. The reinforced design with cylindrical roller bearing is manufactured with greasing nipples in frame sizes 160 to 355.
