Compression Rings

Gray cast iron and steel piston rings are manufactured in different processes. At JPPR, gray iron piston rings are cast as individual rings in a noncircular shape. The rings are generally machined to the required shape by means of double-cam turning, a process in which the ring blank, already axially ground, is copy-turned simultaneously on the inside and outside diameters.

Steel piston rings are made from a profiled wire. The rings are coiled into a circular shape, then the gap is cut out. The necessary shape is obtained using a heat-treatment process in which the rings are mounted onto an arbor appropriately designed to impart the required radial pressure distribution.

Scraper Rings

The ring step is produced in a rectangular or undercut (Napier) design. The advantage of the undercut step is that when the ring twists, a sharp downward scraping edge will still be available to conduct the oil quickly from the ring’s outer edge into the step’s reservoir. This prevents oil from gathering at the scraping edge and diminishing the scraping effect.

Oil-Control Rings

JPPR commonly produces five different types of two-piece oil-control ring bodies. Variations on ring land geometry and running face coating give many options for oil consumption and wear performance.
