The SIG Fan Balancer is a precision, high-tech instrument capable of detecting the smallest out of balance situation. It all starts with the shaft. The shaft on the Fan Balancer is made from high-speed steel (the same steel used for drill bits and machine tools) manufactured to a straightness of 1/1,000 mm and utilizing precision machine ground ends. Then the shaft is suspended between two powerful rare earth magnets. All that would make for a good fan balancer but at SIG, we went the extra step. We added an adjustment screw so that you can precisely adjust the spacing so that only ONE end of the shaft is touching a magnet. This provides for the least amount of possible friction.
