Measurement system for straightness of hole centerline and bearing journal

Measurement system for straightness of hole centerline and bearing journalCan be used for precise alignment of hole centerlines, bearing journals, and other cylindrical objects. It is designed specifically for applications such as engines, compressors, transmissions, and stern tubes, and can accurately measure apertures between 80 and 500 millimeters.

Flexible installation options

The XT950 system has strong versatility with brackets of different sizes, making it easy to install detectors in holes of different diameters. The magnetic pulley can fix the detector in an accurate position, thereby achieving stable and precise measurements.

Intuitive user experience

The hole center program in XT application guides users to complete the entire measurement process with simple operation. The system will automatically calculate the horizontal and vertical positions and roundness of the bearing journal (hole). You can use different fitting calculation methods to evaluate the results, analyze different reference point selections, and set tolerance values.

High precision over long distances

Each component is carefully designed to achieve the highest precision and stability, while ensuring reliability, capable of achieving a resolution of 0.001 millimeters over distances up to 40 meters. This makes the system suitable for both manufacturing environments and on-site services.

measurement procedure

The following featured programs are commonly used in this system,

hole center
This program can measure the straightness of hole centerlines, bearing journals, and other cylindrical objects. Measure 3 to 50 points (multiple points) at each location. If necessary, tolerances can be set. The results can be displayed as fitting calculations, and individual points can be remeasured.

Numerical - Extended Applications

This numerical program can be used for most geometric measurements (as long as the elements and supports are appropriate). Plays well throughout the entire machine installation phase. The numerical interface can display the values of four measurement units simultaneously, including measurement units or digital level gauges. It can automatically record (set interval and duration), and you can record each measurement point separately.
