Introduction to the measurement of the overpin diameter (OPD) of internal gears (spline).
NMP Caliper NMP CIF-150-C
By comparing measurements with the master using the NMP caliper, high-precision measurements can be performed. With a dedicated setup, anyone can easily take measurements.
Measuring the over-pin diameter of internal gears and internal splines, as well as measuring the ball spacing such as between-pin diameter measurements, will become easy for anyone to do. - Zero adjustment with a ball (sphere) measuring device on the master - Measure the product - Confirm the measurement values by comparing with the master Please check the introduction video on YouTube.

Applications/Examples of results
The inner measurement caliper can measure not only the over-pin diameter of internal gears but also, by replacing the measuring element, various measurements such as: - The bottom inner diameter of internal grooves like snap ring grooves - The bottom inner diameter of cups - Special area measurements that allow for inner diameter measurement while avoiding the central shaft If you consult with us, we can propose measurement methods. Main clients: Icing Group, manufacturers of automatic transmission-related parts.
