Angle encoders with integral bearing

A major hallmark of HEIDENHAIN angle encoders is their very high system accuracy. This makes them particularly advantageous in demanding applications for machine tools, measuring machines, telescopes, printing machines, etc. Because the bearing is integrated into the encoder, machine component bearings have no effect on the measuring accuracy. The following overview helps you rapidly select the appropriate encoder series for your application based on the following characteristics:

  • Measuring method
  • Shaft type
  • System accuracy

Selecting an encoder series then gives you a complete list of available variants that you can filter according to more criteria. Each article entry shows you all of the information about the orderable item:

  • Specifications
  • ID number
  • Mounting instructions
  • Brochure
  • CAD data

If you have any remaining questions, you can initiate a product query right from the article entry. This sends us all of the data on the preselected product, allowing us to react to your query with speed and precision.
