Technical Vibration Analysis & Testing
ZGBK utilizes high-precision transducers measuring velocity in µm/s across three critical frequency bands: Low (unbalance), Medium (raceway waviness), High (surface roughness).
TECHNICAL SPECIFICATION
Bearing Vibration Standards & Technical Specifications
Bearing Vibration Standards are the primary indicators of a bearing's manufacturing quality and rotational smoothness. By adhering to international standards, ZGBK ensures silent operation for precision applications. For a complete understanding of how materials impact these levels, refer to our Materials & Accuracy Standards.

* Vibration velocity limits in µm/s. Frequency bands: Low (unbalance), Med (waviness), High (roughness/dust).
Understanding Noise Grades (V vs Z)
V-Grade (V1, V2, V3): Measures vibration velocity — best indicator of structural integrity.
Z-Grade (Z1, Z2, Z3): Measures vibration acceleration in dB — correlates to audible noise.
Environmental Factors Affecting Vibration
ZGBK recommends using high-purity synthetic greases for noise-sensitive applications. Ensuring correct bearing seat tolerances prevents ring deformation — a leading cause of vibration.
Predictive Maintenance & Installation
Proper installation using induction heaters and precision alignment tools is vital. A bearing "forced" onto a shaft will immediately lose its V3 rating due to internal stresses.
