DESIGN
Depending on the application, our top and second rings can have various running surface topographies, including the barrel faced type and the keystone type.  The end gap can be a straight cut, angled cut or gas tight type for improved sealing. Radial pressure distribution greatly influences ring performance therefore we modify the pressure distribution according to the individual application.

The wear-resistance and running-in behavior of the outer ring surface is defined by selecting from various coating options, which include the high-performance electroplated, thermally sprayed and PVD coatings.  Goetze modern oil control rings scrape off oil from the cylinder wall, leaving just the required amount for lubrication. 

The running surface is the contour of the ring facing the cylinder surface. The objective of this running surface profile is to create a lubrication slot with a hydrodynamic film which the piston ring can slide on without touching the other surface. An optimized asymmetrical-barrelled running surface ensures low lubricant consumption even after a very long running time.

Goetze OE piston rings for gasoline and diesel engines, are developed for automobile, light commercial vehicle and heavy-duty applications. Goetze piston rings, which come in a wide range of sizes, include the first ring sets introduced for Euro4-compliant engines.

Manufactured to the industry-leading Goetze Norm Form specifications for aftermarket conditions, Goetze piston rings provide:

• Maximum durability
• High wear and corrosion resistance
• Excellent heat-conducting capacity
• Optimal fit

Goetze piston rings have anti-scuffing properties that promote smooth engine operation, reduced oil consumption and long engine life. In addition, the Goetze process helps prevent materials from detaching and cracking and aids in environmental protection
