MarShaft MAN is a universal, modular shaft measuring instrument for the fast and flexible measurement of shaft-type testpieces.
Precision workpieces can be produced cost-effectively and to a high level of quality across all manufacturing stages – from cutting to length through to hard finishing – if the individual process steps are kept consistently stable. That is exactly where production-floor characteristics testing with MarShaft MAN comes in. Short feedback times on reaching the tolerance limits and seamless documentation of all functional data relating to the component soon pay off.
The MarShaft MAN shaft measuring center is the right solution for your quality control.
The MarShaft MAN shaft measuring center is available in a number of different instrument sizes (workpiece lengths up to 400 mm / 800 mm / 1200 mm / 1600 mm / 2000 mm / 2400 mm, diameters from 120 mm to 220 mm) and its modular design allows it to be adapted to individual measuring tasks. The measuring modules (e.g. diameter, length, roundness module) can be arranged in any order or can easily be added at a later date.

The MarShaft SCOPE plus is a universal, fully automatic optical shaft measuring system for testing rotationally symmetrical workpieces.
The MarShaft SCOPE plus has a highly accurate roundness measuring axis (C), a vertical measuring axis (Z) and a horizontal measuring axis (X).
A tactile measuring system with an inductive measuring probe is available as an option, for measuring radial and axial run-out or straightness, for example. The measuring device is calibrated to the optical measuring system, so it can perform tactile and optical measuring tasks in combination.
The new MarWin EasyShaft software provides a high level of flexibility and exceptionally user-friendly operation.
The measuring sequences are carried out fully automatically, free from operator influences.
The MarShaft SCOPE plus is suitable for use in both the harsh workshop environment and in the inspection room. Zoom functions allow the smallest details to be measured, which with conventional measuring methods are difficult if not impossible to test.
- Automatic measuring procedure
- Matrix camera, 1280 x 1024 pixels
- User-friendly touchscreen operation
- One measuring instrument for multiple measuring tasks
- Good workshop compatibility
- MarWin EasyShaft software provides a high level of flexibility and user-friendly operation

The role of dimensional metrology is expanding at a dramatic rate, in parallel with innovations in manufacturing processes. Given the ever more stringent accuracy requirements and falling cycle times in production (turning, milling, grinding, etc.), rapid measurement directly at the manufacturing machine is absolutely essential. Measurement at the point of origin of the product, with rapid feedback to the manufacturing process to avoid waste. Mahr’s flexible MarShaft SCOPE 250 plus shaft measuring machine offers the right measuring solution for the fast, precise and fully automatic measurement of rotationally symmetrical workpieces in production.
The MarShaft SCOPE 250 plus has a high precision roundness measuring axis (C) and a vertical measuring axis (Z) with a measuring range of 250 mm. At its heart is the state-of-the-art, high-resolution CMOS matrix camera (live image) with an image field of 1088 x 2048 mm. The extremely high image acquisition rate of over 120 images per second keeps measuring times to a minimum. Zoom functions allow the smallest details to be measured, which with conventional measuring methods are difficult if not impossible to test.
Performance features at a glance:
- New, high-resolution CMOS matrix camera with a 40 mm live image field allows fast scanning with over 120 images per second
- High accuracy for diameter and length measurement
- Extremely fast measuring times thanks to high measuring speeds of up to 200 mm/s
- By using Mahr’s MarWin software platform, you can benefit from our decades of experience in length, shape, position and contour measurement

Mahr, the application specialist, provides a completely new measurement method for the camshaft and now (optionally) also for straight and helical cylindrical gears using the new MarShaft SCOPE 600 plus 3D: The combination of optical and tactile sensors allow for the first time ever the functionally complete 3D inspection of the workpiece in one clamping. Due to this market need, Mahr further developed the highly anticipated and well-received MarShaft SCOPE 750 plus system. The advanced system now utilizes a new 2D probe system, a motorized tailstock and a calibration for the linear axes. A matrix camera optically measures characteristics such as diameters, lengths, radii, geometries, location characteristics, cam angle or cam lift in seconds. The additional 2D probe system detects features that are not optically measurable: concave cam profile, all common gear parameters on cylindrical gears, axial run out, reference elements in the axial direction such as blind holes. For this system, the tactile and optical systems are calibrated in one measuring coordinate system. The measuring station operates in conjunction with the MarWin software platform, thus providing full 3D functionality.
