Acoem Runout Probe

The pre-alignment steps of machinery shaft alignment are fundamental and critical for ensuring accurate alignment. To facilitate this process, we have developed the Runout Probe pre-alignment tool. It is the first displacement probe that can be integrated with a laser alignment system.

This app-based tool connects wirelessly to any tablet or mobile phone, including the Acoem NXA Shaft Alignment System. It is capable of performing a variety of pre-alignment checks, such as:

  • Axial and radial runout on flanges
  • Movement of machine feet (soft foot)
  • Bearing clearances
  • Movements due to pipe strain
  • Thermal growth on machine casings
  • Eccentric or skewed mounting of coupling hubs
  • Bent shafts

    Measurement Methods

    Bearing Clearances

    Correcting bearing clearances is important for achieving good alignment results. The Bearing Clearance program allows users to:
    • Check for excessive bearing clearances radially and axially
    • Detect bearing wear
    • Save results to a report

    Measurement Methods

    SoftCheck™

    Soft foot conditions need to be corrected before any shaft alignment takes place. The SoftCheck™ program allows users to:

    • Measure the actual movement on each foot of your machine
    • Achieve perfect results with clear on-screen guidance
    • Save results to a report

    Measurement Methods

    Runout

    Bent shafts, skewed or eccentric mounting of coupling hubs can cause harmful vibrations. The Runout program allows users to:
    • Check runout on shafts and couplings with just one rotation
    • Confirm their measurement location onscreen and receive measuring guidance
    • Save results to a report

    Measurement Methods

    Sensor Display

    This digital version of a dial indicator measures and records relative movement. The Sensor Display program allows users to:

    • Measure thermal growth or pipe strain
    • Utilize two sensors to take simultaneous measurements

    Measurement Methods

    Max-Min

    Function to measure the displacement of an object to a rotational center. The Max-Min program allows users to:

    • Measure radial and axial runout on shafts and hubs
    • Utilize two sensors to take simultaneous measurements

    Explore the Setups

    Runout

    Runout can be measured by placing the probe tip on the machine shafts and coupling(s).

    SoftCheck™

    Measure soft foot by placing the probe tip on any machine foot.

    Bearing Clearances

    Check for bearing clearances by placing the probe tip on the shafts near the bearings.
