The simplified description of common standards and parameters related to bearing noise
创建于06.03
criteria
ISO 16281: Method for measuring noise of rolling bearings.
JB/T 10991: Chinese Machinery Industry Standard for Noise Detection of Bearings.
Key parameters
Noise level (dB)
- General bearings: ≤ 40 dB (low-noise environment).
Precision bearings: ≤ 35 dB (e.g. for motors and instruments).
Silent bearings: ≤ 30 dB (e.g. for medical and office equipment).
2. Measurement Conditions
Speed: 30% to 70% of the rated speed.
Load: Light load or no load (depending on the specific application scenario).
Influencing factors
Bearing type (ball bearings are quieter than roller bearings).
Precision grade (the smaller the tolerance, the lower the noise).
Lubrication condition (either insufficient or excessive grease may increase noise).
