NKE Austria releases series of NU, NJ & NUP roller bearings

April 21, 2016 - Bearing manufacturer NKE Austria GmbH released its series of single row cylindrical roller. The applications of this type of bearing are as numerous: they are used in pumps and compressors, mechanical presses, electric motors, gearboxes, traction motors and axle bearings for railway vehicles, in steelworks and in many other industrial applications.

The bearings are available in 164 sizes in design variants NU, NJ and NUP. The bearing cages are available in roller-guided and outer ring-guided versions and are made from brass and polyamide, with pressed steel versions available, too. In addition to radial clearancegroup CN (C0) as standard, group C3 models are also available. Special versions, for example traction motor bearings (SQ1) and electrically insulated bearings (SQ77) are available at short lead times.

To maximize their lifespan cylindrical roller bearings are made from clean bearing steel. The surface finish of the raceways further helps reduce friction as well as lowering the operating temperature. The geometries of raceways and rolling elements increase the loading capacity, while a modified cage design improves the formation of lubricant film. TMisalignments can be compensated through a modified contact geometry and crowned inner raceways. Tighter tolerances for the roller sorting ensure a uniform load distribution.
