ISO 6020-3:20 15规定了孔径为250 mm至500 mm的单杆紧凑型系列液压缸的公制安装尺寸，用于16 MPa（160 bar[1]）的压力，这是常用液压缸互换性的要求。 注1 ISO 6020的这一部分允许液压设备制造商在公制油缸的设计中具有灵活性，并且不限制技术开发，但确实提供了基本指南。 注2紧凑型系列尺寸最适用于方头气缸。 ISO 6020-3:20 15仅适用于制造产品的尺寸。它不适用于它们的功能特征。 [1]1巴=0.1 MPa=105巴；1MPa=1N/mm2。

ISO 6020-3:2015 establishes metric mounting dimensions for single rod compact series hydraulic cylinders with bores from 250 mm to 500 mm for use at 16 MPa (160 bar[1]), as required for interchangeability of commonly used hydraulic cylinders. NOTE 1 This part of ISO 6020 allows manufacturers of hydraulic equipment flexibility in the design of metric cylinders and does not restrict technical development, but does provide basic guidelines. NOTE 2 The compact series dimensions are most applicable to square-head cylinders. ISO 6020-3:2015 applies only to the dimensions of manufactured products. It does not apply to their functional characteristics. [1] 1 bar = 0,1 MPa = 10⁵ Pa; 1 MPa = 1 N/mm².
