The Bearingizing Tool combines roller burnishing with peening action. As the tool is rotated at a high speed the rolls spin, rise, and fall over a cammed arbor, delivering up to 200,000 rapid fire blows per minute to the work surface. The peaks and valleys of the machined surface are compacted into a smooth, hardened, and ultra fine surface finish.

Standard tool specifications

Bearingizing tools provide three roll positions over the cammed arbor (see right). When the forward (#1 position) of cam becomes worn, the roll cage can be repositioned to the # 2 and # 3 positions by exchanging positions with the moveable collars. This presents NEW cam surfaces and original BUILD-UP. After all positions on the cam are worn beyond producing acceptable parts, oversize rolls can be used to further extend tool life. Roll sizes are available in increments of .0001 inch (.0025 mm) and the tool will accommodate a range of roll sizes up to .002 inch (.0508 mm).
