Mounted Miniature Ball Bearings

Mounted Miniature Ball Bearings

Introducing to industry a range of mounted miniature ball bearings

Mounted Miniature Ball BearingsThese bearings are designed for use in efficient and cost-effective applications in a variety of instruments and mechanisms. They are especially suited for the medical, pharmaceutical, scientific and other precision-oriented fields as they eliminate any need for designing, manufacturing or assembling precision mounts. To mount – simply screw the pillow blocks in place.

Up until now there has been a void in the marketplace for precision mounted miniature ball bearings with existing mounted ball bearings typically available only in shaft diameters no smaller than 12mm. But now the new Spyraflo mounted, miniature ball bearings meet the increasing demands by design engineers for an economical and precision bearing mounting method for smaller shaft sizes. This important development relieves engineers of having to design and produce specific mounting configurations for miniature ball bearings.

High Quality Aluminum Pillow Block
The new Spyraflo product consists of high-quality stainless steel ABEC 3 precision Japanese made ball bearings mounted in a precision-machined, sintered aluminium pillow block housing. Initially they are being offered as non-aligning types as primarily because they are designed for use in more precise applications. These miniature ball bearings will be offered in both inch and metric sizes from 4mm to 10mm shaft diameters, double shielded bearings that are pre-greased for life. The aluminium body and stainless steel, together with the double shield give the new bearings a level of corrosion resistance that makes them the ideal choice for food and wash down applications as well.

Major Engineering Advantage
In the past when considering the use of miniature bearings for an assembly, one of the critical design elements was precisely how the bearings could be mounted. Typically the mount had to be precision machined particularly when using high-performance miniature bearings. Until now no mounted bearing option existed so manufacturers and assemblers were required to produce some form of precision mount. These innovative new Spyraflo bearings eliminate this task effectively and economically. The design criteria of these new mounted, miniature ball bearings mean the assembly process could not be simpler, just purchase the bearings and screw the pillow blocks in place.

Alio News Letter….March 2009 issue: crystallography
The application shown here is a four axis system ideally suited for protein crystallography.

The application was at Argonne National Labs where the ALIO solution was chosen over Aerotech for two main reasons, first by having the ability to produce equipment that could deliver tighter rotational run-out specifications than could be manufactured by the competition. Second, by being able to offer a complete solution, here again the competitor could not include the XY on the face of the stage therefore their solution was only partial, thus meaning a second vendor would have to be included and therefore a second control system.

The application required a sample to be loaded into the tooling that is mounted to the face of the XY then the lower Z axis moves the sample into the beam line. The air bearing R rotates the sample on the centreline of rotation for perfect positioning.

What is Crystallography?

Crystallography is the experimental science of determining the arrangement of atoms in solids. In older usage, it is the scientific study of crystals. The word ‘crystallography’ is derived from the Greek words crystallon = cold drop / frozen drop, with its meaning extending to all solids with some degree of transparency, and graphein = write.
Before the development of X-ray diffraction crystallography (see below), the study of crystals was based on the geometry of the crystals. This involves measuring the angles of crystal faces relative to theoretical reference axes (crystallographic axes), and establishing the symmetry of the crystal in question. The former is carried out using a goniometer.
The position in 3D space of each crystal face is plotted on a stereographic net, e.g. Wulff net or Lambert net. In fact, the pole to each face is plotted on the net. Each point is labelled with its Miller index. The final plot allows the symmetry of the crystal to be established.
Crystallographic methods now depend on the analysis of the diffraction patterns that emerge from a sample that is targeted by a beam of some type. The beam is not always electromagnetic radiation, even though X-rays are the most common choice. For some purposes electrons or neutrons are used, which is possible due to the wave properties of the particles. Crystallographers often explicitly state the type of illumination used when referring to a method, as with the terms X-ray diffraction, neutron diffraction and electron diffraction.
These three types of radiation interact with the specimen in different ways. X-rays interact with the spatial distribution of the valence electrons, while electrons are charged particles and therefore feel the total charge distribution of both the atomic nuclei and the surrounding electrons. Neutrons are scattered by the atomic nuclei through the strong nuclear forces, but in addition, the magnetic moment of neutrons is non-zero. They are therefore also scattered by magnetic fields. When neutrons are scattered from hydrogen-containing materials, they produce diffraction patterns with high noise levels. However, the material can sometimes be treated to substitute hydrogen for deuterium. Because of these different forms of interaction, the three types of radiation are suitable for different crystallographic studies.
