Danfoss Char-Lynn 2000 Series orbital motor 104-1022-006

The Danfoss 104-1022-006 is a published Char-Lynn 2000 Series single-speed orbital hydraulic motor. Its complete factory model code is M02049AC02AA0100010000000AAAAF. The identified execution has a 80.6 cm³/rev geometric displacement and a Geroler gearwheel set with disc-valve distribution.

This article uses a two-bolt SAE A mounting flange, a straight output shaft and staggered side ports. The main connections are 7/8 - 14 UNF-2B SAE O-Ring port; the case-drain connection is 7/16 - 20 UNF-2B SAE O-Ring port. Its shaft specification is Dia. 1 1/4 inch, 3/8 - 16 UNC-2B thread in shaft end. The factory card lists tapered roller bearings and a standard NBR shaft seal.

The motor converts hydraulic pressure and flow into shaft torque and rotation for low-speed drive applications. Select operating points jointly from the displacement-specific torque/speed envelope and the continuous, intermittent and peak duty regions. Inlet pressure, pressure differential and case pressure are separate limits; shaft torque and bearing loads must also be respected. Series performance data are typical at 25 cSt, and installation, fluid and case-drain conditions govern suitability.
