English FAQ (Product Detail Page)
Q1: What is the difference between A2FO and A2FM?
A: A2FO = Hydraulic Pump, A2FM = Hydraulic Motor. They share the same bent‑axis structure, mounting size and displacement, widely used as matched pump‑motor sets for excavators.
Q2: What do model codes mean?
- 56: Displacement 56 cc/rev
- 61R: Series version & right‑hand rotation
- PBB05: Oil port layout, mounting flange and seal configuration
Q3: Core advantages?
High‑speed stable performance, high volumetric efficiency, strong wear resistance, low noise, long service life under continuous heavy‑load working conditions.
Q4: Can they replace original Rexroth parts directly?
A: Yes. Standard flange, shaft and oil port dimensions, plug‑and‑play without modification.
