Single row cylindrical roller bearings are engineered to accommodate high radial loads in combination with high speeds. They feature two integral flanges on the outer ring and a separable design that facilitates mounting and components interchangeability.



NU Series: Can accommodate axial displacement in both directions.
NJ Series: Can accommodate axial displacement in one direction.
NUP Series: Can locate the shaft axially in both directions.

Enhanced Operational Reliability: The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film, ensuring smooth operation even under rapid accelerations and peak loads.
