BT77 Bearing tester is a handheld, pocket-size, user friendly instrument for fast and easy measurement of bearing condition in preventive/predictive maintenance. Bearing tester measures shock pulses with an external impact probe and RPM sensor.
Modern industrial maintenance requires informed decisions on measures to optimize equipment and component performance. Timely failure prediction and detection is a key to cut machine down-time and reduce operating costs. Machine breakdowns are frequently caused by bearing damage. Unplanned downtime, as well as unnecessary repair work, can be significantly reduced by periodically checking the pulse of bearing health! |
