Soft Bearing Suspensions for Turbo Balancing Machine



Features & Advantages

SBS-30’s bearings supports up to 30 kg per pair (15 kg each). Its design allows balancing rotors with a maximum shaft’s diameter of 63.5 mm (2.5 in).

The Soft Bearing Suspension mechanism allows you to improve balancings with very high precision on almost any kind of rotating parts. With this system, all balancings will be performed at higher frequencies than the support’s natural frequency. This system allows the rotor to rotate around its gravity center instead of its geometric center.

The SBS-30 Soft Bearing Suspensions will help you make a very versatile balancer with the high accuracy of soft bearing systems.
