Air Bearings offers bearings that come preloaded with vacuum to give you more control over the fly height and air gap stiffness.

As with all our products, the vacuum preloaded air bearings use Porous Media Technology™ to provide no contact motion. The naturally porous carbon substrate uniformly distributes air over the surface of the bearing, creating a stiff cushion that eliminates friction.

Our vacuum preloaded line replaces a portion of the surface area of our flat round bearings with a region dedicated to vacuum pressure. This combination of vacuum and air pressure can be finely tuned to adjust the fly height and stiffness for superior damping. This means that only one flat guide surface is necessary instead of two parallel, flat guide surfaces as in opposed bearing preloading.

Flexure Pivot journal bearing is a type of bearing designed for high-load, high-speed, small-diameter shafts. It achieves low cross-coupling and high stability while eliminating pivot wear, high contact stresses, and pad flutter.

Flexure bearings, which include flexure pivot bearings, are engineered to be compliant in one or more angular degrees of freedom. They serve much of the same function as conventional bearings or hinges but require no lubrication and exhibit very low or no friction.

Journal radial fluid bearings, also known as journal bearings, are a type of plain bearing that supports radial loads by allowing a shaft to rotate freely within a supporting sleeve. They do not use rolling elements like balls or rollers to support the radial loads, but instead rely on a film of oil or lubricant to reduce friction and minimize wear. These bearings can be designed using hydrodynamic or hydrostatic technology, where the shaft 'floats' on a film of oil or lubricant, significantly reducing wear and vibration.
