NKE Austria Manufactures 3,000 Types of Roller Bearings in New Assembly Plant
According to NSKs press releae, more than 3,000 types are made to order in NKEs new assembly plant in Steyr, Austria.
The modular production facility enables short lead times on all products. The applications of the new single row cylindrical roller bearings include pumps and compressors, mechanical presses, electric motors, gearboxes, traction motors and axle bearings for railway vehicles, in steelworks and many other 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 soon. In addition to radial clearance groups CN (CO) as standard, C3 and C4 groups are also available. Special versions, for example traction motor bearings (SQ1), wheel set bearings (SQ2) and electrically insulated bearings (SQ77) are available at short lead times.
Cylindrical roller bearings are made from clean bearing steel. The surface finish of the raceways further helps reduce friction as well as lower 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.
Misalignments can be compensated through modified contact geometry and crowned inner raceways. Tighter tolerances for the roller sorting ensure a uniform load distribution.
