TFC Introduces New Metric Hoopster Retaining Rings

TFC is the leading European supplier of Smalley Spirolox Retaining Rings, Snap Rings and Wave Springs and we are pleased to announce the launch of our new Metric Hoopster Retaining Ring Series.

The new metric range complements our existing imperial series but has been designed to suit specific standard metric bore and shaft sizes. Hoopster® Retaining Rings offer an innovative way to retain mechanical components when radial space is a particular problem. The Hoopster's minimal radial projection and shallow groove depth allows it to fit where standard circlips and retaining rings cannot. The Hoopster's low profile and precision circularity allow it to be an unobtrusive component in an assembly. These rings are suitable for light and heavy loads and are especially ideal for thin wall tubes or cylinders where the groove depth associated with a conventional retaining ring is likely to be a problem. Despite their narrow radial section, they can absorb high thrust loads since their low profile will not twist or deform under load as with conventional retaining rings and circlips. Over 150 new rings are available from 10 mm to 76 mm and are manufactured in carbon spring steel and 302 stainless steel as standard. Hoopster Retaining Rings are easy to install & remove without special tools and, since they are made in the same way as all of our other innovative Smalley products, there are no tooling charges involved making special custom designs practical and economical. TFC offers complete information on the Metric Hoopster® range including dimensional data, standard part numbers and available materials.
