Handheld bearing checker

First Quarter 2006 Other technologies

Small, lightweight, and easy to use, SPM Instrument of Sweden is offering its Bearing Checker, a portable measuring instrument for fast evaluation of ball and roller bearing condition. It is a suitable introductory instrument condition based maintenance of machinery as a means to cut production costs.

A full-scale condition monitoring system can be a substantial investment. To allow customers to make inroads in condition-based maintenance, SPM Instrument AB produced this affordable instrument. Target groups are plant mechanics, machine operators and maintenance technicians.

It is a well known fact among maintenance personnel that bearing damage is one of the most common mechanical machine failures. However, bearing damage does not usually happen overnight but progresses over time, causing shocks in the bearing. Through regular shock pulse measurement, the development of the damage can be monitored. Bearing Checker measures shock pulses on bearings produces a green - yellow - red status indication showing whether damage is developing and its severity. Maintenance and repairs can then be scheduled for an appropriate time, not causing major production losses. Unnecessary repair work based on experience and recommendations on running time can be avoided and money can be saved.

This pocket-size instrument, weighs 185 g, and measures 158 x 62 x 30 mm. Besides shock pulses, Bearing Checker measures machine surface temperature with infrared light, and can also be used as an electronic stethoscope for listening to machine sounds. Bearing Checker is user friendly and requires minimum training. The instrument can be used on most rotating machinery, such as electrical motors, fans and pumps, in a diversity of industrial environments.
