Market Segments


NBC is working on enhancing its design and manufacturing capabilities with the aim of active participation in the “Make-in-India” initiative. NBC’s recent acquisition of Kinex Bearings in Slovakia, which has vast experience in aerospace bearing design and manufacturing, gives the synergy to kick-start this segment.

NBC is collaborating with various leading research institutes and centres in India and abroad to develop advanced design, testing and validation capabilities and is gearing up to provide aerospace-bearing solutions by establishing a world-class bearing manufacturing facility with AS9100 certifications and necessary NADCAP certifications.

In general, aerospace bearing applications demand high speed (up to 65000 rpm) and extreme temperatures (-54 to 300°C) requirements, manufacturing with high precision class, using high clean steel (SAE 52100, M50, M50NiL) processed through VIM/VAR route, adapting specialized heat treatment processes and NDT techniques for the soundness of the bearing. These bearings featured with an extended inner ring with puller grooves and modified outer rings with flanges, slots for anti-rotation and oil grooves to suit the typical application requirements.
