2000 Series Geroler Motor, 8.00 cu in/rev, 4 Bolt Mounting Flange, 32mm Straight Keyed Shaft, G 1/2 BSP Ports, Standard, wheel or bearingless configurations|Lowest pressure drop motor in the industry|Highly-efficient Geroler motor provides energy savings

Description & Features

Engineered for precision, the 2000 Series Geroler Motor is designed for demanding applications such as swing motors, brush cutters, mowers, and harvesting equipment. Featuring a robust 8.00 cu in/rev displacement, this motor is equipped with a 32mm straight keyed shaft for reliable power transmission. Its 4 bolt mounting flange ensures secure installation in various configurations.

With its G 1/2 BSP staggered ports, this motor offers versatile connectivity options. Notably, it boasts the lowest pressure drop in the industry, enhancing energy efficiency. The motor's high torque rating of 385 newton metres makes it suitable for heavy-duty tasks, while its compatibility with premium anti-wear hydraulic fluids ensures longevity and performance.

To optimize motor life, a break-in period is recommended, and the motor should be filled with fluid before use. Designed for temperatures up to 180°F and pressures up to 2000 PSI, this motor provides robust performance under challenging conditions.

Product Questions & Answers (1)

Question by: Gary A on Oct 29, 2025, 6:13 PM

runs about 385 newton meters of torque on paper, but how's it hold up on something like a swing motor that cycles constantly through the day?

Answer by: Customer Support on Oct 31, 2025, 8:16 AM

Swing motor duty cycles put real stress on hydraulic motors, and the 2000 Series handles that application well. The Geroler disc design is built for efficiency, which means less heat buildup over long operating stretches. That said, you'll want to keep fluid viscosity in the recommended 100 to 200 SUS range during operation, and the max case pressure without a drain line is 2000 PSI. If your system runs continuous back pressure above that, you'll need to run an external case drain and make sure the motor case stays full at all times. Also worth noting: the manufacturer recommends a break-in period of about an hour at 30 percent of rated pressure before putting it to full load. Skip that step and you're shortchanging the motor's long-term durability.
