Roundness/cylindricity tester
Roundness/Cylindricity Tester – Precision Measurement for Rotational Accuracy
A Roundness/Cylindricity Tester is a high-precision metrology device used to evaluate the geometric accuracy of rotational components. It measures how closely the shape of a part (such as a shaft, bearing, or sleeve) conforms to a true circle or cylinder.
These instruments are indispensable in industries requiring tight geometric tolerances, as even minor deviations can impact performance, increase wear, or lead to assembly issues. Using highly sensitive probes and rotary tables with air bearings, modern testers ensure accurate and repeatable measurements that comply with standards like ISO 1101, ASME Y14.5, and DIN EN ISO 4291.

How to Use a Roundness/Cylindricity Tester
- Surface Cleaning: Remove debris or oil from the part to ensure measurement accuracy.
- Centering & Leveling: Mount the component on the rotary table and align it precisely using leveling and centering tools.
- Select Parameters: Choose the measurement type such as roundness, runout, or cylindricity.
- Probe Placement – Align the stylus precisely on the test surface to ensure accurate surface measurement.
- Measurement Cycle: The table rotates while the probe collects surface data.
