该SAE标准相当于ISO标准6626。 如果存在差异，附录中显示了相关依据。 本文件规定了DSF-C型、DSF-CNP型、SSF型、GSF型、DSF型、DSF-NG型和SSF-L型螺旋弹簧控油环的基本尺寸。 对于铸铁部件，根据SAE J1590，推荐材料为10级。对于特殊应用，可以使用材料类别20至50。 根据个别制造商的建议，可以在普通或镀铬版本中使用与这些不同的表面设计和弹簧槽。 螺旋弹簧加载的控油环的切向力可以在很宽的范围内变化。第6节给出了解释和建议。 螺旋弹簧加载控油环轴向宽度的正常范围（3至8 mm，包括3至8 mm）分为0。5或1.0 mm台阶。在表9至14中，给出了现有应用中轴向宽度为4.75 mm（即3/16英寸）的螺旋弹簧加载油控制环的尺寸，以英寸为单位。 本文件适用于往复式内燃机用螺旋弹簧加载的油控制环，直径达200 mm（含200 mm）。它也可用于在类似条件下工作的压缩机的活塞环。

This SAE Standard is equivalent to ISO Standard 6626. Differences, where they exist, are shown in the appendix with associated rationale. This document specifies the essential dimensions of piston ring types DSF-C, DSF-CNP, SSF, GSF, DSF, DSF-NG, and SSF-L coil spring loaded oil control rings. For the cast iron part the recommended material is class 10 according to SAE J1590. For special applications material classes 20 to 50 may be used. Variation in face design and spring groove from these may be used, as recommended by individual manufacturers, in plain or chromed versions. The tangential forces of coil spring loaded oil control rings can be varied over a wide range. Explanations and recommendations are given in Section 6. The normal range for axial width of coil spring loaded oil control rings (3 to 8 mm inclusive) is divided into 0.5 or 1.0 mm steps. In Tables 9 to 14 dimensions are given for coil spring loaded oil control rings within an axial width of 4.75 mm (i.e., 3/16 in) for existing applications in inch units. This document applies to coil spring loaded oil control rings up to 200 mm inclusive for reciprocating internal combustion engines. It may also be used for piston rings of compressors working under similar conditions.
