The Anderon is a unit of bearing vibration equal to 1 μm/s RMS velocity. It was developed by the bearing industry (named after the Anderson meter) to quantify rolling element bearing vibration during manufacturing quality checks at a standard speed of 1800 RPM.

ISO 15242 defines methods for measuring vibration of rolling bearings. It specifies three frequency bands: Low (50–300 Hz), Medium (300–1800 Hz), and High (1800–10000 Hz). Each band captures different defect types. ISO 15242 defines the measurement method only — it does not specify acceptance limits.

What do the frequency bands represent?

Low band (50–300 Hz): waviness of raceways. Medium band (300–1800 Hz): surface roughness and minor defects. High band (1800–10000 Hz): micro-defects, contamination, and noise. Acceptance limits for each band are set by the bearing manufacturer or agreed between manufacturer and customer — ISO 15242 does not specify them.

How do I convert μm/s to Anderon?

1 Anderon = 1 μm/s RMS velocity. So the conversion is direct: a measurement of 50 μm/s = 50 Anderon. The measurement is typically performed at 1800 RPM inner ring rotation with outer ring fixed.

What are typical Anderon limits for good bearings?

For ABEC-1 (P0) bearings: Low band < 50 And, Medium < 40 And, High < 35 And. For ABEC-5 (P5): Low < 25 And, Medium < 20 And, High < 15 And. Precision grades have even tighter limits. These are representative industry values, not ISO 15242 limits — always check the bearing manufacturer's acceptance specification for the exact bearing type and size.
