Typically, a dial indicator is employed to measure the radial runout of a pump shaft and bearing. This measurement is crucial in verifying the proper alignment of the shaft and bearing, as well as identifying any excessive vibration or misalignment within the pump system.
To carry out the measurement, the dial indicator is initially mounted near the shaft or bearing under examination. Then, the indicator's probe is positioned against the surface of the shaft or bearing, perpendicular to its axis of rotation.
Subsequently, the shaft is slowly rotated while carefully observing the dial indicator. Any deviation or movement of the shaft or bearing from its ideal centerline will be displayed by the indicator. For an accurate representation of the radial runout, the measurement is typically taken at multiple points around the circumference of the shaft or bearing.
The measurement is recorded as the maximum deviation from the ideal centerline, usually expressed in thousandths of an inch or millimeters. This value is subsequently compared to the manufacturer's specifications or industry standards to determine if the shaft and bearing meet the required tolerances.
If the measured radial runout exceeds the allowable limits, corrective actions such as realignment or replacement of components may be necessary to ensure optimal pump performance and prevent premature wear or failure.
The radial runout of a pump shaft and bearing is typically measured using a dial indicator. This measurement helps to ensure that the shaft and bearing are properly aligned and that there is no excessive vibration or misalignment in the pump system.
To measure the radial runout, the dial indicator is first mounted close to the shaft or bearing being tested. The indicator's probe is then positioned against the surface of the shaft or bearing, perpendicular to the axis of rotation.
Next, the shaft is slowly rotated while observing the dial indicator. The indicator will show any deviation or movement of the shaft or bearing from its ideal centerline. The measurement is typically taken at multiple points around the circumference of the shaft or bearing to get an accurate representation of the radial runout.

The radial runout of a pump shaft and bearing is typically measured using a dial indicator. The dial indicator is placed near the shaft or bearing and it measures any deviation or movement from the ideal circular path. This provides an accurate measurement of the radial runout, helping to determine if the shaft and bearing are properly aligned or if there are any issues that need to be addressed.
