Eaton 103-1038-012-NP Hydraulic Motor

The Eaton Char-Lynn 103-1038-012-NP is a compact S-Series hydraulic motor engineered for high-torque, low-speed rotary actuation in industrial and mobile hydraulic systems. It delivers 13.7 in3 displacement, providing substantial torque at slow rotation for duties such as hoisting, winching, conveyor drives, and other positioning tasks where steady torque matters. The unit uses a 2-bolt SAE A mounting pattern and a 1-inch keyed shaft for secure coupling to drive components, and SAE #10 O-ring ports for hydraulic connections. As a Char-Lynn S-Series motor, it is commonly listed as a direct replacement for Eaton Char-Lynn S-Series motors, ensuring compatibility with existing manifolds and fittings in legacy equipment and retrofit projects. Availability from distributors as a replacement unit underscores its role in equipment refresh cycles, offering consistent torque characteristics and robust construction in demanding hydraulic circuits.
