This motor belongs to the low-speed series and has a displacement of 80.3 cm³/rev with a maximum operating power of 12.5 kW, making it an optimal choice for mechanisms with high loads at low speeds.

Design Features

In the MR series, special rollers are installed in the gear ring, which evenly distribute the load on the teeth, reduce friction, and minimize wear. This ensures increased engine efficiency even at high pressure and extends service life. The main ports are located on the side and have G1/2" threads, while the drain port is equipped with G1/4" threads. Various shaft, flange, and port options are available upon request.

Shaft and Seals

• Straight shaft ø25, parallel key A8x7x32 DIN6885
• Standard shaft seal
• Other shaft options available upon request (see technical documentation in PDF)

Applications

• Various special and industrial machinery
