~Preventing pinion shaft rotation with uniform 360º circumferential coverage and economical custom manufacturing~
A 2-turn external non-standard XWS series Spirolox Retaining Ring is used to prevent the pinion shafts spinning when the gears are rotating. The ring snaps securely into the external groove of the flanged housing and, because the radial wall is uniform around its total 360º circumference, the flats on the four pinion shafts are able to clear the outer edge of the ring by a consistent 0.50mm in each case.
Our Smalley product, unlike a die stamped equivalent circlip, is produced by edge winding from a continuous coil of single filament pre-tempered round-edge flat wire and does not require heat treatment after forming. This unique process results in a retaining ring that has no ‘ears’ to interfere with the assembly and, because there are no tooling charges involved, it is possible to produce non-standard section rings economically and quickly in carbon steel, stainless steel, coppers and many other alloys. TFC offer over 6,000 standard parts with some series designed to suit Imperial and DIN groove standard circlip grooves.
