Spherical Air Bearings mean Frictionless Motion-Image

Specialty Components, Inc.'s standard SRA series spherical bearings provide frictionless motion in a very compact envelope with convenient mounting features. Whether withstanding the rigors of testing multi-ton spacecraft or providing highly accurate frictionless wafer-plane alignment in semiconductor tools, this versatile design offers a wide performance range and application use.

Multiaxis rotational freedom is often achieved using a spherical air bearing. Specialty Components, Inc.'s standard SRA series spherical bearings provide frictionless motion in a very compact envelope with convenient mounting features. Whether withstanding the rigors of testing multi-ton spacecraft or providing highly accurate frictionless wafer-plane alignment in semiconductor tools, this versatile design offers a wide performance range and application use.

The standard series offers a unique galling-resistant bearing surface which allows for occasional contact between the two rotating components. This property is essential in research applications where frequent assembly and disassembly of the payload occurs. These bearings also include a proprietary vibration dampening feature which greatly lessens the onset of air film instability or pneumatic hammer due to possible dynamic changes in the payload assembly.

The gimbal-type support can support side and vertical load capacities ranging from 1 kg to 10,000 kg. Housing materials may include: stainless steel, aluminum, brass, glass, nickel, super invar, Macor, PEEK, ceramic, graphite, porous carbon and others.
