MOUNTED MINIATURE BALL BEARING LINE

Description

Spyraflo Inc., inventor and sole manufacturer of self-clinching and self-aligning bearing technology, announced the introduction of the industry’s first line of mounted, miniature ball bearings. The new bearings are 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. With the advantage of simply screwing these pillow blocks in place, they 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 one-half inch. 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. They relieve engineers of the responsibility of having to design and produce specific mounting configurations for miniature ball bearings.

Major Engineering Advantage
Previously, 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 design criteria of these new mounted, miniature ball bearings mean the assembly process couldn’t be simpler: purchase the bearings and screw the pillow blocks in place.

“Our new bearing line offers engineers an opportunity to take advantage of the miniature mounted ball bearings in a wide range of applications and to do it much more cost effectively,” says Spyraflo COO, Peter Allen.

High Quality Aluminum Pillow Block
The new Spyraflo product consists of precision Japanese stainless steel ABEC 3 ball bearings mounted in a precision-machined, sintered aluminum pillow block housing. The aluminum body and stainless steel bearing combination, together with the double shield, give the new bearings a high level of corrosion resistance. 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 in both inch and metric sizes from 1/8” to 3/8” (4mm to 10mm) shaft diameters, as double-shielded bearings that are pre-greased for life. In addition, sealed miniature ball bearings are available as an option and are an ideal choice for food and wash down applications.
