The Autoload Seta-Shell 4-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 800kgF, 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.
