Or bearings - Import export

Based on our many years of experience in developing and manufacturing high-quality machine components, GMN has specialized in the area of high-precision ball bearings as well as the production of high-performance and long-lived deep groove and spindle ball bearings to meet – or even exceed – the highest precision classes P4 and ABEC 7. Certification under international standards ensures the highest precision in the development and manufacturing of GMN ball bearings and guarantees constant, outstanding qualities related to speed suitability, stability and longevity. The broad product range includes a large selection of standard solutions as well as requirements-tailored special designs.

The use of high-precision radial groove ball bearings is especially recommended when axial forces are supported in two directions, but the installation space makes the use of a spindle bearing pair impossible; plus when the best-possible guide for rotating components is needed, but the RPM requirements are less important. Depending upon the load capability and the installation space available, GMN provides deep groove ball bearings in sizes 60 and 62 as per DIN 625. A large selection of various cages, lubricants and covers make it possible to adapt GMN deep groove ball bearings to any application.

For many applications such as machine tools, medical devices, vacuum and measuring equipment, as well as complex bearing systems, GMN develops and offers special ball bearings which meet our customers’ specified requirements.

Magnetic ball bearings are increasingly important in CO2 laser systems and fluid pumps as well as applications in the optics industry. GMN has led the development and manufacture of safety bearings, so-called ‘touchdown bearings’ since the middle of the 1990s."

In addition to our special bearings, GMN develops and manufactures ready-to-install, complex bearing systems. By assigning your entire bearing project to GMN you can fully focus on your core competencies.

In rotary encoders with integral bearing and stator coupling, the graduated disk of the encoder is connected directly to the shaft to be measured. The scanning unit is guided on the shaft via ball bearings, supported by the stator coupling. During angular acceleration of the shaft, the stator coupling must absorb only that torque resulting from friction in the bearing, thereby minimizing both static and dynamic measuring error. Moreover, the coupling mounted on the stator compensates axial motion of the measured shaft. Other benefits of the stator coupling are: Simple mounting Short overall length High natural frequency of coupling Hollow-through shaft possible

HEIDENHAIN angle encoders with integral bearing are characterized in particular by very high system accuracy. The integral bearing in the encoders eliminates any effect on measuring accuracy from the bearing of the machine components. The integrated stator coupling in the RCN/RON/ECN series encoders guarantees lowest possible error from the effect of tolerances in the shaft coupling. All angle encoders with integral bearings feature shaft seals that ensure resistance to contamination (IP64 protection). These encoders enjoy an entire spectrum of possible applications in machine tools, measuring machines, telescopes, printing machines and many other areas. Absolute measuring method Hollow shaft diameter (up to 50 mm) Integrated stator coupling Simple installation Typical field of application: Rotational axes with reduced accuracy requirements
