Piston Ring Types - Compression Ring - Anglo Agriparts
WEBKeystone Piston Ring: The keystone ring is used in the top groove of a piston. It is a compression ring with a wedge cross section. Its tapered sides create a running surface allowing radial movement of the ring in the grooves during engine operation which cause the axial clearance in the groove to increase and decrease reducing sticking.
Types of Piston Rings
WEBKeystone rings are side angle rings used in diesel engines to maintain clean grooves in diesel environment. The axial width is thinner on ID than OD. Our Wiper style ring has a notched face on the lower OD of ring for scraping of oil along cylinder wall.

The Material Details & Evolution of Piston Ring Technology
WEBAug 3, 2017 · A diesel engine’s top ductile iron ring is referred to as a “keystone ring”. The keystone ring resembles a sideways triangle, and is also known as a self-actuating ring. The up and down motion of the piston keeps the keystone ring loaded in the ring groove of the piston and as a byproduct, also keeps the ring groove clean from the soot of ...
Piston ring - Wikipedia
WEBA piston ring is a metallic split ring that is attached to the outer diameter of a piston in an internal combustion engine or steam engine. The main functions of piston rings in engines are: Sealing the combustion chamber so that there …

Aftermarket - Hastings Piston Rings
WEBPrimarily used in diesel applications, the Full/Half Keystone type prevents carbon build up and ring sticking. It also creates additional surface area for side load bearing. Coatings include: Plasma Moly, Hard Chrome, Ceramic Chrome, Diamond Chrome, Gas …
Pistons and Rings – The Technical Price for Horsepower
WEBMar 11, 2016 · Ductile iron top rings in diesel applications were often referred to as “keystone” rings because the keystone shape resembles a sideways triangle and the ring groove of the piston is triangular in shape. Keystone rings are still used today and the benefit is these are a self-actuating ring.
WEBto design a ring to fit an existing keystone groove, the first step of the program is to determine the theoretical width of the groove at the outside land diameters of the piston.
The Dimensioning of Keystone Piston Rings and Grooves - SAE International
WEBThe design of keystone rings and grooves as shown in SAE Standard J929 are compared with some modified designs for diesel and heavy duty engines. A proposed standard is offered to eliminate problems encountered due to the variations.
