Adaptive diagnostic technology provides monitoring of rolling bearings in running machines without stopping them. Bearing monitoring uses the signals of:

  • Rotation phase of the rotor, on which the bearing is installed and
  • Vibration measured at a point on the machine housing in 2 (for ball bearings) and 3 (for roller bearings) mutually perpendicular directions.

Implementation of adaptive technology requires a set of technical means, including:

  • Triaxial vibration sensor with integrated preamplifier;
  • Rotor phase sensor (RPM sensor);
  • Devices for installation of sensors on the object,
  • Data input module providing signals normalization and their AD conversion;
  • Computer with software module that implements the adaptive technology.

Scale for condition assessment
Assessments of bearing condition are given in a relative scale, characterizing the dynamic amplification factor of the loads transmitted by the rotor onto the bearing and housing. The lower limit of the scale, tending to zero, corresponds to perfect tracks at almost zero radial clearance. Scale value of 100% corresponds to the level of roughness/unevenness of tracks, which leads to doubling of rotor loads transmitted to the housing. This scale value is not an upper limit, but only serves as a reference degree of tracks unevenness.


Remote diagnostics of rolling bearings.

Service - remote diagnostics

Remote diagnostics of bearings is carried out on the data arrays transmitted through the Internet. To implement remote diagnostics the Customer should have the technical means for recording the signals of vibration and phase. When preparing the services, there shall be technical specifications for measurements and requirements for data format, as well as a list of bearing types and their technical data. Within the framework of the service we can provide full solution and delivery of the technical means for performing vibration tests.

Options for providing services on remote diagnostics:

  • One-time diagnostics of bearings upon request
  • Regular monitoring of bearings alongside with the maintenance of a database
  • Monitoring of bearings and rotor vibration.
Products - diagnostics system delivery

Depending on the Customer's activity profile, the technical means are available in various complete sets:

  • For companies engaged in maintenance and repair of machines in industry, transport and energy production - in the form of a portable kit
  • For industrial companies with automated production and limited personnel - in the form of an extensive system of sensors fixed on the most critical machines and sensors for periodic monitoring of other objects.
Brief description

Diagnostics methodology provides an assessment of unevenness of dynamic load distribution between intermediate gears of the planetary gear. Application of the method in testing the gearbox on the stand allows you to control the assembly quality and timely detect those gears which are prone to increased wear and premature failure. The method can also be used as a part of on-board HUMS type systems.


Software for the method of vibration-based diagnostics of planetary gear adapted to a specific object in accordance with Customer's project requirements. A set of technical requirements for the measurement system on site or a technical solution for its implementation. Support and maintenance of the system.

Brief description

Our diagnostic systems for aircraft engines (and other turbo-machines) are based on the use of the Vibropassport of the engine type, consisting of parameters characterizing the functioning of its units as mechanical systems. The Vibropassport provides fine-tuning of the engine and identification of sources of excessive vibration during the test on the stand, monitoring and diagnostics of individual modules during engine operation.

Depending on the Customer's task, the Vibropassport can be integrated into the system of measuring and diagnostics of the testing rig, diagnostics system for on-board monitoring of engine condition, monitoring system for pumping units, etc.


Software and a complex of engineering solutions for the vibration-based diagnostic system for aircraft engine (turbo-machine) based on its Vibropassport.

Development phases:

  • Development and approvals of the complex of technical solutions
  • Vibropassport development, including:
  • Research of engines structural and dynamic properties
  • Adaptation of diagnostic algorithms of standard units
  • Development of methods and algorithms for diagnostics of specific units in accordance with the Customer's project specification
  • Test trials of a given type of engines to establish initial and allowable limit values of diagnostic parameters
  • Development of software for implementation of the Vibropassport and database
  • Diagnostic system testing in laboratory and full scale conditions
  • Experimental operation of the system
  • Software support and maintenance of the system

Depending on the Customer's profile, the system can be:
