Product description

Runner Block

Runner Block with mounted adapter plate and mounted scanner

• Same mounting hole pattern and mounting dimensions as Standard Runner Blocks
  

• An adapter plate enables the scanner* to be replaced during servicing without removing the Runner Block.
  
  

* Scanner fastening screws must be accessible. There must sufficient clearance at the end of the rail to remove the scanner.

Guide rail

Guide rail with integrated steel scale

• Same mounting hole pattern and mounting dimensions as Standard Guide Rails
  

• Incremental scale (1), and optional absolute code band (2) (IMS-A), or reference marks (IMS-I).
  

• Scales (1)/(2) protected by a hermetically sealed welded stainless-steel band (3)
  
  

Integrated Measuring System IMS for Ball and Roller Rail Systems

Rexroth Ball And Roller Rail Systems can be supplied with a completely integrated, inductive position measuring system. The position measuring system consists of a scanner, a scale, reference marks, and the absolute code band. The scanner with sensors is mounted on the runner block. As it travels over them, it evaluates the scale, the reference marks or the absolute code band which are incorporated into the guide rail. This mechatronic system combines the functions of guidance and measurement into one unit and opens up new, ideal opportunities in machine design.

Highlights: Integrated measuring system

• The guide system and the measuring system form one unit, building on standard guide elements (it is possible to use a standard runner block on the IMS guide rail)
  

• No additional space is required
  

• No external mounting surfaces are required for measuring systems
  

• No measurement inaccuracies due to parallelism offset between the measuring system and the guide system
  

• Retrofit and replacement is simple due to the proven Rexroth interchangeability
  

• Position measurement directly on the workpiece/tool
  

• Protection type IP67 with no additional measures required
  

• Thanks to full integration of the measuring system components into the guide system, no complex installation or adjustment work is needed
  

• The runner block, scanner and guide rail can each be individually replaced during servicing
  

Inductive measuring principle

• Contact-free scanning ensures zero maintenance
  

• Resistant to water, oil, dust, shavings, etc.
  

• Insensitive to magnetic fields
  

• One-piece guide rails: standard length up to 4,500 mm
  

• Several sensor units can be mounted on one rail
  

Incremental measuring procedure

• Precise position detection thanks to a high-precision, incremental scale combined with distance-coded reference marks or single reference marks
  

• High resolution thanks to 40 µm signal period
  

Absolute measuring procedure

• Precise, absolute position detection thanks to an additional absolute code band
  

• No battery necessary for buffering the absolute information
