Anderon Band Converter
Convert compatible RMS radial velocity measurements for the L, M and H bands to Anderon values under the documented 1,800 r/min test condition.
Converted Band Values
Condition-specific conversion
Sugawara defines Anderon from radial displacement density differentiated by rotation angle, band-pass filtered, expressed as an RMS quantity and normalized by the square root of passband octaves. For 1,800 r/min and its L/M/H division from 50 to 10.8 kHz, it gives 1 Anderon ≈ 7.698 μm/s.
Measurement context
| Band | Sugawara frequency range at 1,800 r/min |
|---|---|
| L | 50–300 Hz |
| M | 300–1,800 Hz |
| H | 1,800–10,800 Hz |
Sugawara unit definition and current analyzer band documentation provide the numerical relation and bands.
ISO scope
ISO 15242-1:2015 specifies fundamentals and calibration under established conditions. ISO 15242-2:2015 covers specified radial ball bearings with cylindrical bore and outside surface; it is not a general installed-machine severity standard.
No grading: no ABEC-based thresholds, PASS/FAIL decision or overall RSS is applied. Use the exact bearing test specification and agreed acceptance limits.
No. Under the stated 1,800 r/min L/M/H condition, Sugawara gives approximately 7.698 μm/s per Anderon.
No. Enter matching RMS radial velocity band values from the compatible bearing test.
This converter applies no universal acceptance limits. Use the exact agreed bearing specification.
Sugawara defines H as 60–360 waves per revolution; at 1,800 r/min (30 Hz), that is 1,800–10,800 Hz.
The outputs are separately normalized band quantities; no sourced universal combined grading rule is applied.
The procedures described on this page were developed and field-tested by the Vibromera team using the Balanset-1A, a portable dual-channel balancer and vibration analyzer for on-site rotor balancing.
