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.
