The Erbessd Instruments SBS Series Soft Bearing Suspension are balancing support kits intended to provide you a way to build your own balancing machine at a very low cost with very high performances. 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 SBS Series can support maximum loads of up to 25 tons. The SBS has an elevation screw to adjust the height in case that the rotor supports have different diameters. With the floating 3-Axis liberty the SBS can auto-align the rotor, thus permitting easy rotor loading and unloading.

Available models cover a wide range of capacities: SBS-30 (33lb each), SBS-150 (165lb each), SBS-300 (330lb each), SBS-1000 (1100lb each), SBS-2000 (2200lb each), SBS-4500 (4960lb each), SBS-6000 (6613lb each), SBS-10T (11023lb each), SBS-15T (16535lb each), and larger models up to SBS-50T supporting up to 25 tons per side.
