Active condition monitoring instead of passive damage limitation
BeMos allows them to actively look into their warehouse instead of just passively listening from outside. This allows you to react to errors before damage occurs. In order to give their warehouse a long life, use BeMos One Effects of sound transmission in solids.
BeMOS transmits sound pulses. Many thousands. Every second.
Each individual sound pulse collects important information on its way across the bearing: Has a rolling element just passed by? Is there enough lubricant on the track? Does contact even occur between ball and track?
The generated sound propagates on the bearing ring in the form of surface acoustic waves (saw for short). These waves are influenced by their boundary conditions. Stresses in the material and adjacent media, such as those caused by passing rolling elements, change the speed and dampen the sound. Conversely, the boundary conditions can be inferred from the properties of sound transmission.
- How fast does the cage rotate?
- What load does the bearing have to withstand right now?
- Does slippage occur?
Overload can quickly damage a bearing. Excessive tensions in the contact zone between rolling element and track cause the material to tire and lead to breakouts in tracks and rolling elements (pittings). The high pressures and temperatures that arise during rolling contact also cause the lubricant to age more quickly. You can identify an overload in the warehouse based on the characteristic values that BeMos one generates from the transmitted sound pulses.
But a load that is too low can also damage a bearing. If the load falls below a minimum load, slippage is easy. The rolling elements then no longer roll across the track but slide on it. This leads to increased friction in rolling contact and thus to damage to raceways and rolling elements. Often, such damage is detected too late. Only when the warehouse is loaded again will the advance damage result in a very short period of time. With BeMos One Do you recognize slippage and can take countermeasures during design, but also later in operation.
Based on the cage speed and the geometry of the bearing, the pressure angle can be calculated. With BeMos one, this is even so precise that the system can be used for quality assurance during warehouse production. However, knowing the pressure angle is also an advantage when operating rotating machines, such as pumps. The pressure angle can be used to determine the load that is currently acting on the bearing. In this way, you can find the optimal operating point for your machine in order to achieve the longest possible lifespan.
Discover our advanced rolling bearing measurement technology
Our innovative ultrasonic technology enables precise monitoring and quality control of rolling bearings. With the ability to check even closed warehouses, our system optimizes the QA process, saves time and reduces sources of error.
Determine axial thrust
The running time of centrifugal pumps depends largely on the load on the bearings. With the METAX measurement method, axial forces can be recorded during operation, service intervals extended and operating conditions optimized running time.
Gearbox design
In a transmission, the bearings are exposed to constantly changing loads. Careful design of the entire drive train is necessary to ensure that the bearings are optimally loaded and supplied with lubricant at every operating point. BeMos One helps them do that.

Detecting particle contamination and lubrication failure in wind turbine support bearings using surface acoustic wave measurement and machine learning
Detection of particle contamination and lubrication failure in transmission support bearings of wind turbines using the measurement of acoustic surface waves and machine learning"Text: “This work presents a measurement method using Surface Acoustic Waves (SAW) to detect particle contamination and oil supply failures. The SAW method offers advantages compared to traditional monitoring methods such as vibration measurements, as it is based on the propagation behavior of actively introduced SAW in the warehouse. As a result, the method is robust against interference. A machine learning method is used to evaluate the signals and to identify operating anomalies, which enables online monitoring with minimal delay between data entry and evaluation.
Rolling bearing diagnosis on machine sets (Springer Vieweg Verlag)
The leading expert in condition monitoring, Dieter Franke, has included MetaX technology (formerly BestSens technology) in the standard work for diagnosing and monitoring rolling bearing faults and damage. In chapter 12.3.1 under the heading “Expanding the methodology of rolling bearing diagnosis”, Dieter Franke describes the possibilities of MetaX technology. The new edition was published in 2022 by Springer Vieweg Verlag.
