Description & Features

The Danfoss / Eaton Char-Lynn 2000 Series Disc Geroler Standard motor provides efficient performance for swing motor applications. Featuring a displacement of 18.7 cu in/rev and a 2 Bolt SAE A mounting flange this motor is designed for reliability in demanding environments.

It is equipped with a 1-1/4 in. straight keyed shaft and staggered 7/8-14 St.Thd. O-Ring Ports ensuring secure and stable connections. This motor is highly efficient contributing to significant energy savings.

With a maximum case pressure of 2000 PSI an operating temperature of up to 180 F and a recommended fluid viscosity range of 100-200 SUS it performs well under various conditions. To maintain optimal function the motor should be filled with premium quality anti-wear hydraulic fluid and run for one hour at 30% rated pressure before full load applications.

Regular filtration per ISO Cleanliness Code level 18/13 is recommended. Applications include use in brush cutters mowers and harvesting equipment where the lowest pressure drop in the industry and standard or bearingless configurations enhance performance.

Product Questions & Answers (2)

Question by: Denise P on Jun 5, 2025, 9:46 AM
been looking at this for a brush cutter setup, does the shaft and mount actually line up with standard SAE A equipment or do i need adapters?
Answer by: Customer Support on Jun 6, 2025, 9:10 PM
The 2 Bolt SAE A mounting flange and the 1-1/4 in. straight keyed shaft are both standard configurations, so fitting this into SAE A-compatible equipment should be straightforward without adapters. The ports are 7/8-14 straight thread O-ring style and are staggered, which gives you a bit more flexibility in tight hydraulic connections situations. Just make sure your hydraulic lines are sized and threaded to match that 7/8-14 spec before you button everything up.
Question by: Clint C on Feb 12, 2026, 2:36 PM
Will this motor hold up okay in a mower application, you reckon?
Answer by: Customer Support on Feb 13, 2026, 5:34 PM
Harvesting equipment and brush cutters are listed among the applications for this Eaton Char-Lynn motor.
