Bearing Checker Instrument

NEW - Kittiwake Holroyd’s MHC-Bearing Checker is a unique hand held instrument, providing maintenance engineers with an easy to operate, simple to use and quick method of analysing bearing condition and lubrication state.


The MHC-Bearing Checker monitors high frequency Acoustic Emissions (AE) signals naturally generated by deterioration in rotating machinery. The unique way of detecting and processing these signals gives you condition related information in the easiest possible form. It is a state of the art Condition Monitoring instruments with extreme sensitivity to developing faults.

To find out how the MHC-Bearing can you identify early deterioration in rotating machinery, contact us today.

Simply attach the unit via the magnetic sensor head and within 10 seconds both dB level and Distress® values will be displayed. dB Level is an indication of the overall noise of the bearing and is dependent on speed. It increases with speed of rotation, but also with degradation of the bearing or inadequate lubrication. Distress® gives an instant indication of the state of the bearings health. A Distress® reading below 10 generally indicates normal operation, a reading higher than 10 is usually indicative of bearing damage or the need for attention.

Distress® and dB Level are the fundamental parameters of the high end MHC-Memo and MHC-Classic products offered by Holroyd and trusted by thousands of maintenance engineers and technicians. These are now also available in a low cost, easy to interpret pocket size instrument.

The unit is powered by an internal rechargeable battery, offering up to 1000 measurements between charges. Recharging is accomplished through a micro USB port and the unit can be connected to any standard PC USB port for ease of recharging.

Economically priced, can you afford not to equip each of your maintenance engineers with a unit?
