Axial/radial bearings with integral measuring system

Axial/radial bearings with integral measuring system comprise:

    * an axial/radial bearing YRTM with a dimensional scale and
    * a MEKO/U electronic measuring system. The electronic measuring system contains two measuring heads, a set of shims and an electronic evaluation system.


Bearings of series YRTM correspond in mechanical terms to axial/radial bearings YRT but are additionally fitted with a magnetic dimensional scale. The measuring system can measure angles to an accuracy of a few angular seconds by non-contact, magneto-resistive means.

Advantages of the angular measuring system

The measuring system

    * operates by non-contact means and is therefore not subject to wear
    * carries out measurement irrespective of tilting and position
    * has an automatically self-adjusting electronic system
    * has a self-centring function
    * is unaffected by lubricants
    * is easy to fit and the measuring heads are easily adjusted
    * there is no need for alignment of the bearing and a separate measuring system
    * requires no additional parts
      – the dimensional scale and measuring heads are integrated in the bearing and adjacent construction respectively
      – the resulting space saved can be used for the machining area of the machine
    * does not give any problems relating to supply cables. The cables can be laid within the adjacent construction directly through the large bearing bore
    * gives savings on design envelope size and costs due to the compact, integrated design requiring fewer components.
