Smalley Steel Ring Company (MD&M West Booth 3440) introduces its Hoopster Retaining Rings. Hoopster rings fit into much shallower grooves than regular snap rings or retaining rings. The Hoopster’s low profile, precision circularity, and small radial size allow it to be an unobtrusive component in an assembly. The retaining rings are suitable for light to heavy loads, and are ideal for thin wall tubes. An additional advantage of the Hoopster is its potential for high thrust capacity. The low radial profile will not twist or deform under load as with conventional retaining rings. Hoopster retaining rings are easily installed without special tools. Standard sizes are stocked from 3/8 to 3 in., and are offered in carbon and 302 stainless steel.
