NKE Austria has introduced solid brass bearing cages with an improved design.

With their reduced mass, the cages cut the roller bearings’ energy absorption and prevent sliding friction.

In bearings that operate at high speeds, the force created by the rolling elements’ moving mass causes a significant additional internal load.

Especially in cylindrical roller bearings with relatively heavy solid brass cages, the acceleration of the rolling elements requires a large amount of energy.

A further issue directly associated with the mass inertia of rollers and cage is the sliding friction that frequently occurs in rolling bearings that are insufficiently loaded or accelerated too quickly and which, in extreme cases, can destroy the bearing’s precision-finished raceway surfaces.

With the aim of reducing moving mass, engineers of NKE’s design department have comprehensively revised the existing standard solid brass cage design as part of a design review process.

‘By fully utilising the available weight-savings potential, we were able to cut cage mass by nearly a fifth compared to the previous design without affecting its roller guidance accuracy,’ says Faruk Duskunovic, leader of the NKE design team and responsible for the technical implementation of the idea.

‘At the same time an optimisation of the cage bar cross-sections has resulted in an improved lubricant distribution in the bearing.’ The improved cage design will be gradually phased in for all of NKE’s standard bearings with solid brass cages.

NKE AUSTRIA GmbH – a manufacturer of premium bearings – was founded in 1996 by a group of senior staff members of the former company Steyr Wälzlager. Within a decade, the NKE brand has emerged on the world bearing market as a significant alternative in the premium class.

We offer both standard and special bearings for all industrial applications as well as technical services, including product development, application engineering, consulting, documentation and training.

NKE’s core functions – such as engineering, product development, final processing of components, modular assembly, quality assurance, logistics, sales and marketing – are centralised at our headquarters in Steyr, Austria. The site is certified to ISO9001:2008,  ISO14001:2004 and OHSAS 18001. In April 2006, NKE was awarded the Austria Quality Seal in recognition of its high quality standards.

Today, NKE bearings are distributed in more than 60 countries through over 240 distributors and 18 international representative offices
