MPTR 20PC/AQ, mptr-20pc.jpg


Device to measure radius and deviations of shape and distance from the face of ball bearings.

The measuring device MPTR 20PC/AQ is designed to measure the radius absolute value, shape deviations and the distance from the face in one plane of the rings of ball radial, axial and radial-axial, single-row and double-row bearings.

The device construction is designed for work in the manufacturing measuring laboratories (centres).
