Bearing Torque Analyzer: Detailed analysis of bearing conditions through torque traces

The Bearing Torque Analyzer

The Bearing Torque Analyzer (BTA) is a user-friendly running torque tester that evaluates the condition of bearings. The BTA is easy to set up for various bearing sizes, and system calibration is a simple procedure that takes less than a minute to complete. The BTA measures bearing running torque and displays the torque trace, which is printable, along with the calculated average and peak running torque values, and the maximum and average hash width.
