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

Redi-Sleeve

National® has built a reputation as one of the most respected names in the industry. We have offered premium sealing solutions for more than 75 years. Our design team keeps pace with the industry and provides advanced solutions for today’s vehicles.

Product Features:

• Designed to repair damaged, grooved or worn shafts
• Durable stainless steel construction for corrosion-free sealing surface that surpasses most original shaft specifications
• Ideal for a shaft where indications of seal wear, such as tracks or grooves have developed
• Ultra-thin construction (0.01/0.25mm wall thickness) allows original seal size to be used with minimal additional lip loading
• Easy to install with removable flange and installation tool
• Installation tool reduces sleeve distortion and allows for installation without removal from the shaft

Glyco advanced engine bearing technologies withstand heavy loads and cope with the increasingly challenging conditions of modern, environmentally-friendly engines. Glyco is the world’s largest manufacturer of OE-quality bearings. Every year, our engine bearings are fitted on more than 10 million engines around the world – from small bore engines to heavy-duty commercial vehicles and stationary engines. Driven by the need to reduce CO2 emissions, today’s engines extract more power from less fuel. Due to the increased temperature and load, conventional bearings struggle to cope. Thanks to over 100 years of innovation, Glyco provides bearings with advanced metallurgy that can withstand these challenges. Federal-Mogul invented Glyco Sputter Bearings with twice the service life of conventional bearings. Glyco developed G-188, the first intelligent bearing material, and were also first to launch a full lead-free material portfolio. Recent innovations include the highly durable Glyco IROX bearing shells, which address the challenges of hybrid, stop-start and downsized engines.
