ISO 03019-1:2001 pdf download.Hydraulic fluid power -Dimensions and identification code for mounting flangesand shaft ends of displacement pumps andmotors— Part 1: Inch series shown in metric units.
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.
NOTE Involute spline is in accordance with SAE J744 [‘1.

3 Terms and definitions
For the purposes of this part of ISO 3019, the terms and definitions given in ISO 5598 apply.
4 Dimensions
4.1 Tolerances
Dimensions shown without tolerances are nominal.
Tolerances of form and position are shown in accordance with ISO 1101.
4.2 Selection of mounting flanges and shaft ends
Select flange and shaft dimensions for pumps and motors manufactured in accordance with this part of ISO 3019 from Figures 1 to 6 and Tables 1 to 6, inclusive.
Shaft ends according to Figure 3 and Figure 6 may be provided with a tapped hole.
4.3 Mating components
The dimensions and related tolerances of the mating components shall be compatible with the dimensions and tolerances specified in this part of ISO 3019, thus avoiding undue body strain as well as transverse loads on shafts in excess of those permitted by the pump or motor manufacturer.
5 Identification code
5.1 Mounting flanges
Use the mounting flange identification code given in Table 1 and Table 2.
The number preceding the hyphen (-.) is an approximation, in millimetres, of the mounting flange pilot diameter.
The number following the hyphen is the number of mounting bolt holes in the flange.
5.2 Shaft ends
Use the shaft end identification codes shown in Tables 3 to 6.
The number preceding the hyphen is an approximation, in millimetres, of the shaft major diameter.
The number following the hyphen is arbitrarily assigned as follows:
— cylindrical keyed shaft ends without thread, -1; cylindrical keyed shaft ends with external thread, -2;
— conical keyed shaft ends with external thread, -3; 300 involute spline shaft ends, -4.
6 Flange/shaft end combinations
Use the preferred flange or shaft end combinations given in Table 7. Use other combinations only when necessary, by agreement between the purchaser and the supplier.
