Bearing manufacturer NKE Austria has introduced a series of single-row cylindrical roller bearings. The salient feature of this series is the wide range of variants it comprises: more than 3000 types are made to order in NKE’s assembly plant in Steyr, Austria. In addition to being exceptionally flexible, the modular production facility enables very short lead times on all products.
The applications of the new single-row cylindrical roller bearings are as numerous as its variants: they are used in pumps and compressors, mechanical presses, electric motors, gearboxes, traction motors and axle bearings in many industrial applications.
The new roller 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.
To maximise their lifespan, the new cylindrical roller bearings are made from clean bearing steel. The superior surface finish of the raceways further helps reduce friction as well as lowering the operating temperature. The optimised geometries of raceways and rolling elements increase the loading capacity, while a modified cage design improves the formation of lubricant film. Thanks to the improved design of bearing guiding flanges for NJ and NUP variants, the bearings can take up higher axial loads. Misalignments can be compensated through modified contact geometry and crowned inner raceways. Tighter tolerances for the roller sorting ensure a uniform load distribution.
