Is one Anderon equal to one micrometre per second?

No. Sugawara documents 1 Anderon ≈ 7.698 μm/s for 1800 r/min with the stated L, M and H bands. The relation is tied to those measurement and bandwidth-normalization conditions.

Does ISO 15242 set universal acceptance limits?

This tool does not claim universal ISO acceptance limits. Acceptance criteria require the exact bearing, test conditions and agreed manufacturer/customer specification.

Which bearing scope is identified by ISO 15242-2:2015?

The official ISO abstract covers single- and double-row radial ball bearings with cylindrical bore and outside surface and contact angle up to 45 degrees, with stated exclusions.

Can I use ordinary machine vibration readings?

Not automatically. Values must be RMS radial outer-ring velocity from matching band-pass filters and compatible bearing-test conditions. General installed-machine vibration is a different measurement context.

Why is there no overall RSS or pass/fail result?

The three values are separately bandwidth-normalized band results. This converter has no sourced universal rule for combining them or grading a bearing.

特定条件转换

Anderon ≈ v_band,RMS / 7.698

Sugawara 将 Anderon 定义为径向位移密度对旋转角求导、经带通滤波、表示为 RMS 量并按通带倍频程平方根归一化。对于 1,800 r/min 及其从 50 到 10.8 kHz 的 L/M/H 划分，得出 1 Anderon ≈ 7.698 μm/s。

ISO 适用范围

ISO 15242-1:2015 规定了既定条件下的基本原理和校准。 ISO 15242-2:2015 涵盖具有圆柱形内孔和外表面的指定径向球轴承；它不是通用的已安装机器烈度标准。

无分级： 不应用基于 ABEC 的阈值、PASS/FAIL 判定或整体 RSS。请使用确切的轴承测试规范和商定的验收限值。
