Full title and description

Rolling bearings — Measuring methods for vibration — Part 2: Radial ball bearings with cylindrical bore and outside surface. This International Standard defines standardized procedures for measuring structure-borne vibration of single‑row and double‑row radial ball bearings (contact angle up to and including 45°), specifying test conditions, measurement quantities and evaluation principles for such bearings.

Abstract

ISO 15242-2:2015 provides measurement methods for vibration of radial ball bearings with cylindrical bore and outside surface (single‑row and double‑row, contact angle ≤ 45°). It excludes bearings with filling slots and three‑ or four‑point‑contact ball bearings and is intended for use on dedicated test rigs using the measurement fundamentals and calibration approaches given in Part 1 of the series.

Scope

Specifies vibration measuring methods for radial single‑row and double‑row ball bearings with cylindrical bore and cylindrical outside surface, for contact angles up to and including 45°. The standard is applicable to measurements conducted on test rigs and laboratories under prescribed conditions and excludes bearings with filling slots and three‑ and four‑point‑contact ball bearings. It complements ISO 15242‑1 (Fundamentals) which covers calibration, measurement quantities and general measurement principles.

Key topics and requirements

• Specified measurement quantity and evaluation methods for bearing vibration (default physical quantity: RMS vibration velocity, typically measured in the radial direction).
• Recommended default test speed (example default frequently referenced: 1 800 min⁻¹) with guidance for selecting other speeds based on bearing size and test objectives.
• Requirements for test rig configuration, sensor mounting and measurement direction (radial measurement emphasis).
• Exclusions and applicability limits (no filling‑slot bearings; excludes 3‑ and 4‑point contact ball bearings; contact angle ≤ 45°).
• Reference to calibration and instrumentation requirements described in ISO 15242‑1 (fundamentals) to ensure measurement traceability and repeatability.

Measurement details and typical test parameters are given to enable repeatable characterization of structure‑borne vibration for quality control, acceptance testing and R&D.

Typical use and users

Used by bearing manufacturers, independent test laboratories, OEMs, condition monitoring and vibration analysts, R&D groups developing bearing designs or noise/vibration mitigation, and quality/acceptance teams performing incoming inspection or end‑of‑line testing. The standard supports consistent evaluation of bearing vibration performance across suppliers and laboratories.
