Engineers have significantly improved a diagnostic tool that measures bearing precision. A new torque tester, the RT2C-E Running Torque Tester, developed by Timken Super Precision, now features an improved electronic interface, simplifying the process of recording bearing torque values.

A Timken Co. subsidiary, Timken Super Precision manufactures ball bearings and related products for applications such as airplane instruments and artificial hearts where precision is critical. The RT2C-E Running Torque Tester measures that precision.

“The E doesn’t stand for easy,” stated Doug Cloutier, electrical systems engineer and project leader. “But the RT2C-E is easier to use. It offers our bearing customers a more user-friendly, graphical interface, and provides on-screen torque trace features that provide for fast bearing analysis.”

With this data, users can identify a number of common bearing problems including poor geometry, retainer hang-ups, dirty or contaminated bearings, flat or pitted raceways, and poor race-to-face parallelism within the bearing. “

The standard tooling delivered with the RT2C-E is capable of accepting 26 industry standard miniature and instrument bearing sizes, ranging from 1/8″ to 7/8″ outside diameter. Optional tooling is available to accommodate larger bearing sizes and bearing assemblies, motors and other rotating assemblies.
