Product Details
This vibration analyzer is designed specifically for the structural characteristics of deep-groove ball bearings. It achieves full automation—from material feeding and waiting to inspection, flipping, discharging, and sorting—offering high testing accuracy and excellent repeatability. It eliminates the variability caused by manual testing, resulting in high work efficiency.
This vibration analyzer converts mechanical signals from bearing vibrations into electronic signals via sensors. The electronic signals undergo a series of processing steps—including sampling, filtering, computation, and statistical analysis—to obtain several parameters that characterize bearing quality. By comparing these parameters with reference values, the analyzer can distinguish between different bearing quality grades and automatically classify them into distinct categories. Furthermore, the analysis and statistical evaluation of bearing manufacturing defects can be utilized for quality control throughout the bearing manufacturing process.
The single-axis automatic vibration meter is compact in size and cost-effective, making it ideal for applications with limited space and as a replacement for manual vibration meters. The dual-axis automatic vibration meter boasts high efficiency and a wide variety of loading and unloading interfaces, making it suitable for production lines. The retrofit kit offers an attractive price and a short manufacturing cycle, perfect for customers looking to automate their existing manual vibration meters.
