SBS 300Kg

Soft Bearing Suspensions for Balancing Machine – SBS 300

The Soft Bearing mechanism of the SBS-300 allows you to make very high precision balancings on almost any kind of rotating parts.

Features & Advantages

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.

SBS-300 was designed with thin cantilever roller work supports to allow mounting rotors with very short shafts.
