Seta-Shell Four Ball Tester-Autoload – 19900-4

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 which are 1200, 1475 and 1760 rpm. A load, adjustable in the range of 6 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 seconds 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.

Methods: ASTM D2266, ASTM D2596, ASTM D2783, ASTM D4172, IP 239, BS EN ISO 20623, BS ISO 26422, DIN 51 350
