Guide and measure linear position for ultra-high precision and expert workpiece quality Manufacturing productivity and quality absolutely depend on accurate production machine data - which is why Bosch Rexroth created the IMS Integrated Measuring System to enhance the value and performance of our linear rail technology. Seamlessly integrated into our ball rail and roller rail systems, Rexroth provides choices: The IMS-I incremental measuring system, or the IMS-A, an absolute length measuring system. Both linear encoders provide accuracy comparable to glass measurement systems (without requiring additional machine space) and are ideally suited for external measurement applications in systems such as machine tools.
Rexroth IMS
IMS-A absolute position measurement
IMS-A: Absolute measurement
The IMS-A integrated measuring system offers both absolute and incremental coded scales, with the absolute code band completely integrated into the rail. It provides:
Absolute position information immediately after system start-up
Cost and space savings, since no additional components such as batteries are required
Machine switch-on without a reference run, minimizing production ramp-up time
IMS-I incremental position measurement
IMS-I: Incremental measurement
The IMS-I integrated measuring system uses the inductive measuring principle for non-contact position measuring. It provides:
Precisely engineered incremental scale and integrated reference marks
Absolute positioning measured using inductive sensor to evaluate the incremental scale and individual reference marks
Wear-free due to the non-contact system design
Key IMS Benefits at a glance:
Inductive
All components made of steel
Scale and sensors are not corrupted by external magnetic fields
Wear and maintenance-free
Resistant to contamination and vibration
Not susceptible to EMV interference
Accurate
Repeatability: +/- 0.25µm
Position resolution: 0.025µm
System accuracy: +/- 4µm/m
Coefficient of linear expansion like steel: 11 x 10-6 K-1
Exact positioning even under dynamic load changes
Very good circuit dynamic due to high position resolution
Small rail deviation even with multi-axis interpolation
No thermal compensation necessary with processing steel
Integrated
Simplified design due to full linear guide integration; no attachments needed
Robust and insensitive to dirt and contamination (IP 67 protection type)
No sealing air necessary
Minimum mounting time: the guide assembly is mounted at the same time as the measuring system
Rexroth interchangeability: Comprehensive supply program for Rexroth ball and roller rail systems
