Series of single row cylindrical roller bearings – Unlimited possibilities for equally as many applications

Published: 19 March 2020 - Rachael Morling

Bearing manufacturer NKE Austria GmbH presents 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 wide range of variants it comprises: more than 3,000 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 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 superior surface finish of the raceways further helps reduce friction as well as lowering the operating temperature. The optimized 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.

In addition to these numerous technical benefits, cylindrical roller bearings feature optimum operational reliability and maximum cost effectiveness. All NKE bearings are subject to stringent quality procedures and are tested using state-of-the-art procedures and equipment.

NKE offers both standard and special bearings for all industrial applications. Engineering, product development, production and final processing of components, assembly, quality assurance, logistics, and sales and marketing are centralized at its Steyr headquarters. The factory in Steyr is certified to ISO 9001:2008, ISO 14001:2004 and OHSAS 18001. A wide range of standard bearings is available from stock or at short production lead-times. NKE also provides customized products and solutions. In addition to product development and application engineering NKE provides a full range of technical services, consulting, documentation and training. NKE’s products are distributed through 12 international offices and more than 240 distribution outlets in 60 countries.
