The main feature of these new pillow blocks, now available from Micromech, is that there is no other ball bearing that accommodates a shaft diameter of less than 12mm. Previously an engineer had to fabricate a mount that incorporates a very high precision bearing mounting hole, the Spyraflo solution has removed this problem, all that need to be done is simply screw the housing into place.

The PB series are the industry's first line of mounted miniature ball bearings for small shaft sizes. Designed for efficient and cost-effective application in a variety of instruments and mechanisms used in the medical, pharmaceutical, scientific and other precision-oriented fields, these miniature mounted ball bearings eliminate any need for designing, manufacturing or assembling precision mounts.

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. The new Spyraflo mounted; miniature ball bearings will meet the increasing demands by design engineers for an economical and precision bearing mounting method for smaller shaft sizes. This relieves engineers of the responsibility and work of having to design and produce specific mounting configurations for miniature ball bearings.

In the past when considering the use of miniature bearings for an assembly, one of the critical design elements was how, precisely, 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 when it came to the use of miniature ball bearings, so manufacturing/assembling people were required to produce some form of precision mount. The new Spyraflo bearings eliminate this task effectively and economically.

The new Spyraflo product consists of high-quality stainless steel ABEC 3 precision Japanese ball bearings mounted in a precision-machined, sintered aluminium pillow block housing. Initially, they are being offered as non-aligning types, primarily because they are designed for use in more precise applications. These miniature ball bearings will be offered and metric sizes from 4mm to 10mm (inch sizes available) shaft diameters, as 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.
