Bearing life, vibration severity, thermography, bolt torque and shaft alignment.
Calculate the L10 basic rating life and modified life Lnm of ball and roller bearings per ISO 281, with equivalent load, service factor, reliability (a1), aISO factor and static safety.
ISO 281, equivalent load, hoursClassify vibration of motors, pumps and fans into ISO 20816-3 and ISO 10816-1 zones A, B, C and D, convert displacement, velocity and acceleration, and project when the trend reaches the alarm.
ISO 20816, in/s RMS, zones A to DClassify hot spots in panels, connections, breakers and cables by temperature difference (NETA criteria), correct for inspection load and estimate the temperature at full load.
ΔT, NETA, priority, loadCalculate tightening torque and preload for metric and UNC bolts by ISO 898-1 and SAE J429 grades, with nut factor K or VDI 2230 friction coefficients, and see the preload scatter.
Preload, SAE J429, ISO 898-1Calculate front and rear foot shims and horizontal moves for the motor from offset and angular misalignment, with thermal growth target and tolerances by speed.
Shims, offset, angularity, toleranceImportant notice: Indus Metrics tools produce estimates and pre-sizing results from the data you enter and from published engineering methods.
