Model Number Code

Based on standard hydraulic naming conventions for the A2F series, the model breaks down as follows:

• A2F: Axial piston, bent-axis design with fixed displacement.

• 28: Size / displacement rating of 28 cc/rev (28.1 cm³/revolution).

• W: Port connection location/style (typically indicates threaded or flange-type industrial side ports).

• 2: Series or index generation code.

• Z8: Specific shaft or drive configuration (usually denotes a metric splined shaft matched for heavy machinery gearboxes). [1, 2, 3, 4]
