Seta-Shell Four Ball Tester-Autoload

Part Number 19900-3

The Autoload Seta-Shell Four Ball Lubricant Tester determines the friction properties of extreme pressure oils and greases. Used in tribology research laboratories and in the routine quality control of finished lubrication products.

A ball, mounted in a chuck, is rotated against three stationary balls in a pot containing the sample lubricant. The digital speed controller has three factory pre-programmed settings. A load, adjustable in the range of 40 to 800 kgF, is applied to the balls via a balance beam and electric jack. The applied load is displayed on a digital readout. The torque transferred between the rotating and stationary balls is measured and displayed. The digital timer, with a range of 0.1 second to 9999 hours, can be used to control the duration of the test. If the torque exceeds a preset level, or the balls weld, during a test, power to the drive motor is automatically turned off.
