Internal Combustion Engines--Piston Ring-Grooves
- Ground Vehicle Standard
- J2275_199607
- Issued
Scope
There is no ISO standard equivalent to this SAE Standard.
This SAE standard identifies and defines the most commonly used terms for piston ring-goove charactersitics, specifies dimensioning for groove widths, and demonstrates the methodology for calculation of piston groove root diameter.
The requirements of this document apply to pistons and rings of reciprocating internal combustion engines and compressors working under analogous conditions, up to and including 200 mm diameter and 4.5 mm width for compression rings and 8.0 mm width for oil rings.
The specifications in this document assume that components are measured at an ambient temperature of 20 °C (68 °F).
Tolerances specified in this document represent practical functional limits and not imply process capabilities.

Issuing Committee
Piston and Ring Standards Committee
The Piston and Ring Standards Committee reports to the Powertrain Systems Group of the Motor Vehicle Council. The Committee is responsible for developing and maintaining SAE Standards, Recommended Practices, and Information Reports related to piston and ring components used in gasoline and diesel engines. The committee¿s objectives are to ensure that current engineering practice is reflected in the documents and identify new work items where standardization can serve to advance manufacturing, design or application. The committee serves as the U.S. delegate on the ISO/TC22/WG1, Piston Ring Standards Working Group. Participants in the SAE Piston and Ring Standards Committee include OEMs, suppliers, consulting firms, government, and other interested parties.
