Description & Features

The Danfoss / Eaton Char-Lynn 2000 Series Disc Geroler Standard motor is a highly efficient solution for various industrial applications including swing motors brush cutters mowers and harvesting equipment. This motor features a displacement of 18.70 cubic inches per revolution and operates with a 2 Bolt SAE A mounting flange. The 14-tooth splined shaft ensures a reliable and secure connection while the 7/8-14 UNF-2B SAE staggered O-ring ports ensure optimal fluid transfer.

The motor operates at a maximum case pressure of 2000 PSI without a case drain. For continuous pressures above 2000 PSI using an external case drain line is recommended to maintain motor integrity. The unit boasts the lowest pressure drop in the industry enhancing energy savings by making it an efficient Geroler motor.

Engineered for performance it operates effectively with a fluid viscosity range of 100-200 SUS and up to 180 F maximum operating temperature. To maximize the motor lifespan a recommended break-in period of running the motor at 30% of rated pressure for approximately one hour before full-load application is advised.

Question by: Sherry M on Sep 27, 2025, 2:19 PM
got a mower setup that needs a 2-bolt SAE A mount and a 14 tooth SAE C spline. is that the exact flange and shaft on this motor?
Answer by: Customer Support on Sep 29, 2025, 6:32 AM
It comes with a 2 Bolt SAE A mounting flange and an SAE C splined 14T shaft, so those two connection points match what you described.
Question by: Ross B on Feb 12, 2026, 8:16 AM
What kind of machines is this motor typically found on?
Answer by: Customer Support on Feb 13, 2026, 9:50 AM
Commonly, this Char-Lynn 2000 series motor works well for swing motors, brush cutters, mowers, and harvesting equipment.
