In addition, the labeling has been improved. All important data, including deviations in bore, outer diameter, width and production batch, can now be seen on the outside of the rings and on the packaging. In addition, a QR code on the packaging allows all data to be read out using smartphones or readers and integrated into various database solutions. No additional software or internet connection is required. Customers can therefore identify the product more quickly and easily and also benefit from enhanced counterfeit protection.

Ball bearings for high-speed spindles

With the high-precision ball bearings of the new accuracy classes P4+ and UP+, GMN offers the right components for the increased requirements in the machine tool industry in terms of speed, running accuracy, service life and machining precision.

Tolerance class P4+ fulfills running and form accuracies according to DIN P2 / ISO 2 and dimensional accuracies according to DIN P4 / ISO 4. It is intended as a standard accuracy class for a wide range of applications in the machine tool industry and is available in all designs and series with bore diameters from 5 to 120 mm.

Ball bearings in tolerance class UP+ are designed for applications where the focus is on the highest requirements for performance parameters such as speed, running accuracy and vibrations. UP+ spindle ball bearings meet running and form accuracies according to DIN P2 / ISO 2 or better and are available in the S and SM designs as well as the 60 and 62 series with bore diameters from 5 to 70 mm.

Large selection of standard solutions and custom-made products

High-precision spindle ball bearings from GMN are optimized for high speeds, loads and rigidity and are characterized by a long service life and reliability. They can be configured in a variety of ways so that there is the right design for almost every requirement. They are available in different designs, series, with cages in various designs and made of different materials as well as balls made of 100Cr6 bearing steel or ceramic.

The range includes high-precision spindle ball bearings with bore diameters from 5 to 120 mm as well as various nominal contact angles, accuracies and preloads. GMN manufactures all ball bearings in Nuremberg. Only high-quality materials are used for all components and manufacturing processes. In addition to standard solutions, application-optimized custom-made products are also available on request.
