AA2FM45/61W-VSD510

The AA2FM45/61W-VSD510 fixed displacement motor belongs to the A2FM Fixed Motors series from Bosch Rexroth and is intended for hydraulic automation where compact, high-speed rotary output is required. It provides a geometric displacement of 44.9 cm³ per revolution so each turn delivers a predictable volume of oil flow to the drive shaft. A maximum rotational speed of 5000 rpm allows the unit to connect directly to fast-moving mechanical loads. The bidirectional rotation lets designers reverse equipment motion without adding separate motors, and compatibility with open or closed circuits means it suits both conventional pump systems and closed-loop drives. A 0.6 L case volume stores leakage oil to keep internal parts lubricated, while the SAE J744 four-bolt mounting flange offers a standardized interface for rigid, repeatable installation.

The motor accepts up to 225 L/min of inlet flow, supporting high power delivery when paired with appropriately sized pumps. A nominal pressure rating of 400 bar defines continuous operating limits, and short peaks up to 450 bar can be tolerated during rapid load changes. FKM fluoroelastomer seals contain fluid at these pressures and resist chemical attack from modern hydraulic oils. The assembly weighs 17 kg, permitting single-person handling during maintenance. Rear-facing SAE A and B working ports streamline hose routing on machinery with limited side clearance. These specifications equip the AA2FM45/61W-VSD510 for constant-displacement applications that demand high pressure capability, reversible rotation, and flexible mounting options.
