Here’s a new method for mounting needle roller bearings. The Spyraflo design incorporates a self-clinching retainer which enables drawn cup needle roller bearings to be securely retained in sheet steel as tin as 1mm.
The bearings come in sizes from 4mm to 12mm, in self-aligning, non-aligning, sealed and non-sealed configurations. The self-aligning capability enables designers to use non precision sheet steel assemblies and hole diameters. The non self-aligning version of the bearing is said to be particularly suitable for single bearing cantilever type applications.
