Piston Rings

Optimal Compression, Heat Transfer and Oil Control

Federal-Mogul designs and manufactures nearly all known types of piston ring variations. In Europe, we have developed our own CAD system, called “EMSY” (Engineering Management System) for piston ring design, calculation and drawing with integrated design, variation and production management. Our North American counterpart tool to EMSY is PRISM (Piston Ring Interactive Spreadsheet Model). Our proprietary design tools enable us to produce fully customized piston rings for your specific application.

Both U.S. and European teams manage informational flow through the PTC-designed Windchill system. This allows an optimized synergy of drawing creation, design changes, test documentation and investigation reporting, while offering a secure means for the customer to access sensitive data and test results.

We manufacture our piston rings with different coatings or surface treatments to prevent:

Excessive wear on ring periphery and side faces

Scuffing on the surfaces of both ring and cylinder

Microwelding between ring side face and piston groove

Oil consumption and blowby

Excess friction

We manufacture all known coatings and treatments using the latest technology at the highest level of quality. This includes galvanic chromium coatings, molybdenum flame-sprayed coatings, metal and metal-ceramics plasma coatings, PVD (Physical-Vapor-Deposition) coatings and nitrocarburizing treatments.
