...is itself a bearing material. Applications and tests have involved static loads to 50,000 psi and dynamic loads of 35,000 psi at moderately low rpms.

...a fluid film, they are well suited to supporting heavy load at low speeds. Fluid-film bearings tend to be a better choice if load increases with an increase in speed or if the load is dynamic. On the other hand, pulsating heavy loads on stationary rolling-element bearings can cause brinelling. Both...
) are possible. Static capacity — the maximum force magnetic bearings generate to lift the shaft — is a function of variables such as amplifier current, surface area of the magnetic poles, number of coil windings, and air-gap dimensions. A good rule of thumb is 75 lb of force/sq in. of bearing. Dynamic capacity...

The bearing inner diameter contain three separate oil grooves for generating dynamic pressure, while a triangular-shaped outer diameter promotes...
First, bearings can gall and score shafting especially when using a relatively harder (low embeddability) bearing material. And second, bearing load capacity diminishes proportional to declining film integrity. Next, consider load capacity in both static and dynamic modes. As designs become...

...surface. When the shaft rotates, the fluid shears but remains in place, thus creating a dynamic seal. A typical radial gap between pole pieces and shaft is 0.05 to 0.125 mm, although gaps to 0.25 mm can accommodate eccentric shaft motions. A pressure differential across the seal deforms the liquid ring...
...or typically about 5 N/cm 2 . These MR fluids have the consistency of light grease (relatively low viscosity) in the off state, so dampers can have a broad, dynamic load range.
