The main functions of piston rings in engines are.
Piston ring oil.
Piston ring employs a team of knowledgeable parts professionals that focus on service and supply and partners with industry leading manufacturers.
The oil scraped off the cylinder wall moves into the slots in the back of the oil ring grooves in a piston and from there it returns to the oil pan.
Some rings of this type are installed with expander rings.
Piston rings commonly used on small engines include the compression ring wiper ring and oil ring.
The primary usage of the piston ring is to seal the chamber where the piston is moving which can be a combustion chamber of a 2 stroke or a 4 stroke engine marine engines have three or more types of rings fitted on the circumference of the piston.
A support rail was then necessary to provide a solid surface that the oil ring can rest without fear of bending into pin bore.
A steel napier second ring and industry leading cp 20 oil ring round out the package.
Improving heat transfer from the piston to the cylinder wall.
At hastings we manufacture a bold and broad offering of piston rings one that spans thousands of applications for virtually any engine.
In addition the second rings are reversed twist taper faced cast iron.
Hastings offers piston rings for nearly any application worldwide from automotive and truck to agriculture industrial small engine as well as marine and high performance.
With the most comprehensive line of piston rings compression rings and oil rings in the world we have a piston ring for practically any application racing automotive heavy duty transportation agriculture industrial small engine and more.
We are a family owned and operated local company now in our third generation.
Piston ring has serviced the automotive aftermarket since 1953.
A 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.
Hastings revolutionized oil control ring design with the invention of the hastings flex vent oil control ring and it is now the accepted standard in the industry.
Maintaining the proper quantity of the oil between.
Sealing the combustion chamber so that there is minimal loss of gases to the crank case.
However the second ring also provides a bit of oil control.
For 1 5mm and 1 16 ring sets the top rings are positive twist ductile iron barrel faced plasma moly inlaid.
As you ll see in the photos this support rail must be installed correctly for optimum performance.
The expander spring increases the pressure of the ring on the cylinder wall which improves the oil scraping effect.
The oil ring s main function is to control the amount of oil that makes it between the piston and bore which is necessary for lubrication and heat transfer purposes.
Piston rings are manufactured and classified on the basis of function and usability.
