Hydraulic fluid power - Dimensions and identification code for mounting flanges and shaft ends of displacement pumps and motors - Inch series shown in metric units
This part of ISO 3019 specifies sizes and dimensions and establishes an identification code for the two- and four-bolt mounting flanges and the shaft ends of positive-displacement, rotary hydraulic fluid power pumps and motors. It is applicable to cylindrical keyed shaft ends with an external thread, as well as to those without a thread, to conical keyed shaft ends with an external thread and to 30°involute spline shaft ends.
