Single row cylindrical roller bearing applications

April 25, 2016 By Mike Santora

NKE-bearing-collage-imageBearing manufacturer NKE Austria GmbH has released its series of single row cylindrical roller bearings – a bearing type on which many customers in different industries rely. The salient feature of this series is the range of variants it comprises: more than 3,000 types are made to order in NKE’s assembly plant in Steyr, Austria. In addition flexibility, the modular production facility enables short lead times on products. The applications of this type of bearing are as numerous as its variants: 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 clearance group 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. Thanks to the improved design of bearing guiding flanges of the NJ and NUP variants, the bearings can take up higher axial loads. Misalignments can be compensated through a modified contact geometry and crowned inner raceways. Tighter tolerances for the roller sorting ensure a uniform load distribution.

Cylindrical roller bearings also feature operational reliability and maximum cost effectiveness. The Steyr site is certified to ISO 9001:2000 (design, development, production and distribution of bearings) and ISO 14001.
