Description & Features

Danfoss Power Solutions presents the S Series Geroler Motor with an 18.20 cu in/rev displacement ideal for agricultural equipment like harvesters and seeders. Equipped with a 4 Bolt Mounting Flange and a 1-inch Straight Keyed Shaft this motor ensures reliable power transmission. The 1/2 NPT Ports facilitate seamless integration with hydraulic systems.

Highlighted for its compact yet powerful performance this motor is designed to extend bearing life and improve shaft seal efficiency. Its robust build supports a maximum case pressure of 1500 PSI and operates effectively at temperatures up to 180F.

Engineered with premium anti-wear type hydraulic fluid for optimal functionality the motor requires an initial break-in period running at 30% of rated pressure for one hour. This ensures longevity and reliable performance under full load conditions.

Featuring a torque rating of 491 newton meters and recommended fluid viscosity of 70 SUS this motor meets the stringent ISO Cleanliness Code level 18/13 for filtration. The design and build are specifically tailored for demanding applications.

Product Questions & Answers (2)

Question by: Lynn M on Sep 3, 2025, 10:32 AM
what's the break-in procedure on this motor before putting it under full load?
Answer by: Customer Support on Sep 5, 2025, 6:41 AM
Run it at roughly 30% of rated pressure for about an hour before you throw a full load at it. Make sure the motor is filled with fluid before you start any of that. Skipping that step tends to shorten motor life, so it's worth the extra time upfront.
Question by: Neal S on Feb 1, 2026, 10:06 AM
got a new install coming up. what kinda break-in does this motor need before i put it under full load?
Answer by: Customer Support on Feb 2, 2026, 4:32 PM
For best motor life, run it about one hour at roughly 30 percent of rated pressure before you work it hard. Make sure the motor is filled with hydraulic fluid before you apply any load.
