Bearing Test Systems — Bearing Inspector II — Operating Specs

Bearing Inspector II Torque Testing of Anti-Friction Bearings and Assemblies

Operating Specifications:

  • Input Power: 115 VAC (220 VAC 50 HZ optional)
  • Temperature Environment: 60 to 90 degrees F
  • Humidity Environment: Up to 95% non-condensing

Test Head: A Vibrac Model 9405A test head is the mechanical testing portion of the BRG 3000 Bearing Inspector II System. This test head combines an Optical Torque Transducer, an Optical Encoder and a Variable Speed Synchronous Drive. This combination enables the system to rotate the bearing at a constant and precise speed while measuring both torque and position.

Torque Transducer: A Vibrac Mini Series Static Torque Transducer is used in this test head. The principal of operation for these torque transducers is pictured below.

Standard Torque Transducers: The torque measuring capability of the test head can be changed by simply changing the transducer and then selecting it in the software window shown below.

Torque Transducer Specifications:

Note: Consult factory for other torque values.

Optical Encoder:

  • Line Count: 9000
  • Accuracy: +/- .02 degrees.

Drive Motor:

The system is supplied with a variable speed synchronous drive with a Speed Range of 0.5 to 10 RPM.

Positive Overload Protection

Due to the relatively sensitive nature of the Bearing Inspector transducer, positive overload protection is provided.
