Product Code:SAE J2275
Title:Internal Combustion Engines - Piston Ring-Grooves
Issuing Committee:Piston And Ring Standards Committee
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-groove characteristics, 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 do not imply process capabilities.
