Here is some information that I found online to help understand the product. We bought this and never used it.

The Bosch Rexroth AZMF-12-008UQR12ML (9511290007) is a high-efficiency external gear motor designed to transform hydraulic energy into mechanical torque and rotational speed with optimal precision. This unit is particularly noted for its birotational capabilities, allowing it to operate effectively in both directions which is ideal for varied applications requiring reversible movement. The motor features a straight shaft compliant with SAE J500 standards and mounts via an SAE J744 A bolt flange, ensuring secure and standardized integration into various systems. With a geometric displacement of 8 cm³/rev, the AZMF-12-008UQR12ML gear motor is engineered for consistent performance and boasts an extremely long service life of approximately 1,000,000 actuations. The use of slide bearings allows the motor to handle high loads without compromising on its longevity or efficiency. Its aluminum housing contributes to the unit's lightweight design at just 2.5 kg, while still providing robustness and corrosion resistance. The maximum constant pressure this gear motor can withstand is impressive, ensuring reliability under demanding conditions. It also offers a wide speed range, accommodating different operational requirements. The maximum rotational speed reaches up to 4000 rpm, with a maximum flow of 40 l/min, underscoring the motor's capacity for high-speed applications. Designed with NBR sealing material and standard noise level production, the Bosch Rexroth AZMF-12-008UQR12ML ensures quiet operation without sacrificing performance. The line connections are made via Thread UNB and SAE O-ring for secure fluid transfer. Lastly, this model has been constructed using high-volume production techniques that guarantee consistent quality across units.

8 cm³/rev, Bi-rotational, Straight shaft SAE J744 16-1 (short), SAE J744 82-2 (A) 2-bolt flange, Thread UN-2B, SAE O-ring
The key task of external gear motors is to convert hydraulic energy (flow and pressure) into mechanical energy (torque and rotational speed). To reduce heat loss, Rexroth external gear motors are designed to be extremely efficient. This efficiency is achieved through pressure-dependent gap sealing and high-precision manufacturing technology.
