BS ISO 3019-1:2001

This standard BS ISO 3019-1:2001 Hydraulic fluid power. Dimensions and identification code for mounting flanges and shaft ends of displacement pumps and motors is classified in these ICS categories:

• 23.100.10 Pumps and motors
• 23.100.99 Other fluid power system components

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.

NOTE Involute spline is in accordance with SAE J744^[1].
