Product Overview

The 109-1247-006 geroler orbit hydraulic motor is a universal aftermarket replacement part for original Eaton Char-Lynn 109 series hydraulic drive units, cross-compatible with Danfoss M04099AH11AC03 equivalent hydraulic motors, widely deployed in light & medium-load hydraulic machinery.

It adopts mature integrated geroler disc valve design, which converts hydraulic oil pressure into smooth low-speed high-torque rotary power. All internal core transmission components are precision-machined from wear-resistant alloy material, matched with double-sided heavy ball bearing support and multi-layer NBR sealing structure. The whole motor strictly follows OEM drawing standards for mounting flange, drive shaft, inlet/outlet and drain port layout, realizing true plug-and-play replacement without reworking pipelines or installation brackets.

Compact thickened cast iron outer housing offers excellent resistance to collision, dirt and temperature variation in field working environments. The factory pre-installed built-in check valve effectively suppresses reverse hydraulic pressure surges during equipment shutdown, avoiding uncontrolled sudden rotation and lifting overall operation safety. All finished motors pass complete hydraulic bench testing to verify torque stability, rotation smoothness and zero leakage performance.

Key Features

✅ 1:1 OEM Interchangeability Direct drop-in replacement for Eaton Char-Lynn 109-1247-006 and Danfoss M04099AH11AC03, fully matching original mounting flange, shaft and oil port dimensions with no machining modification needed.

✅ Precision Geroler Disc Valve System High-precision machined geroler gear set paired with balanced disc valve delivers uniform torque output, low pulsation and quiet variable-speed running performance.

✅ Heavy-Duty Cast Iron Housing Solid compact cast iron shell resists mud, dust, impact and wide temperature fluctuation, perfectly adapting to harsh outdoor farm and construction site environments.

✅ Complete Anti-Leak Sealing Package Heat-resistant NBR shaft and body dual sealing blocks internal & external oil leakage, maintaining stable output pressure under continuous long-hour operation.

✅ Dual Front & Rear Ball Bearings Dual bearing layout bears both radial and axial loads, cuts internal friction loss and significantly extends the overall motor service lifespan.

✅ Built-In Anti-Reverse Safety Check Valve Integrated one-way check valve prevents hydraulic backflow and unexpected equipment runaway during power cut-off, greatly improving operator operation safety.

✅ Strict Factory Quality Inspection Each finished unit passes full flow, pressure and leakage testing before delivery to eliminate defective products and guarantee consistent stable performance.
