Description & Features

The Danfoss / Eaton Char-Lynn S Series Spool Geroler is engineered with precision to meet the rigorous demands of agricultural machinery and railroad maintenance equipment. This robust motor features a displacement of 5.70 cu in/rev and a 2 bolt mounting flange ensuring seamless integration into heavy-duty systems.

Designed for extended bearing life and enhanced shaft seal performance this gerotor motor operates efficiently with a maximum case pressure of 1500 PSI and can sustain a maximum operating temperature of 180F. Its 1 in. straight keyed shaft and 1/2 NPT ports are tailored for high durability and reliability making it an ideal choice for harvesting equipment and seeders.

The motor's compact yet powerful design along with its high torque rating of 183 newton metre provides seamless functionality in demanding environments. The recommended break-in procedure requires running the motor for approximately one hour at 30% of rated pressure before applying full load to ensure optimal performance and longevity.

The S Series Geroler Motor with its .500-14 NPTF Dryseal pipe thread ports uses premium quality anti-wear type hydraulic fluid adhering to ISO Cleanliness Code level 18/13. The fluid viscosity is maintained at 70 SUS at operating temperatures.

Question by: Terry B on Apr 22, 2025, 7:00 AM

got a new motor, do i really need to “break it in” or can i just put it to work?

Answer by: Customer Support on Apr 24, 2025, 6:31 AM

For best motor life, run it about one hour at roughly 30 percent of rated pressure before you put it under full load. Make sure the motor is filled with hydraulic fluid before any load is applied.

Question by: Scott J on Feb 24, 2026, 2:26 PM

Is this motor okay for a seeder?

Answer by: Customer Support on Feb 26, 2026, 9:23 AM

This S Series Geroler motor is indeed suitable for seeders, as well as agricultural augers, harvesters, and even railroad maintenance equipment.
