SBS-300 is a balancing support kit intended to provide you a way to build your own balancing machine at a very low cost with very high performances.
The SBS-300 can support up to 300 kg (150 kg each support), and with its 2 roller positions it allows shaft diameters of 152 mm (6 in). Also has an elevator screw to adjust the position in case the tracks rotor supports have different diameters up to 25.4 mm (1 in) and a swinging movement for auto-alignment.
Balancings are done at higher frequencies than the suspension's resonance frequency. With all these characteristics, the system allows the rotor to spin around its gravity center instead of its geometric center.
The rolling elements have a swing system with a pitch up to 10°. This way the SBS-300 gets aligned automatically with the shaft to prevent distortion on the shaft’s rolling surface.
