Bearing Monitoring & Lubrication

A regular condition based monitoring of bearings is essential for a successful preventative maintenance. The early detection of damages or signs of wear in friction and non-friction bearings leads to prevent downtime, increased operational reliability and considerable cost savings.

The SONAPHONE range of devices is used in the most varied of branches of industry. The variety of devices in the range and the extensive accessories available enable this range of devices to be used for a multitude of various applications. The ultrasonic testing device SONAPHONE for bearing testing can also be used in order to check the lubrication and friction level, to interpret defect induced noises and for the preventive inspection of pumps and compressors. In the case of rotary pumps it also allows the possibility of detecting cavitation noises.

This ultrasonic testing device allows to monitor wear at various machinery components and rotating machinery. The ultrasound level can be recorded electronically during the process of individual or serial testing in defined inspection intervalls. All deviations to normal operating conditions can then be transferred from the data logger to a computer and presented in graphic format.
