Product Overview

The 103-1006-012 is a mid-range S Series Geroler orbital motor displacing 13.7 CID, targeting applications where H Series gerotor efficiency falls short but the full 18+ CID S Series models would be oversized. Its constant-clearance Geroler gear set — with rollers at each lobe tip instead of sliding contact — maintains internal volumetric efficiency above 92% across the working pressure band, which directly translates to cooler oil, less internal bypass, and consistent shaft speed under fluctuating load. Rated for 370 N·m continuous at 1,500 PSI and 15 GPM flow, it reaches approximately 250 RPM under full displacement. Cast iron body with 4-bolt SAE mount, 1-inch straight Woodruff-keyed shaft, 1/2-inch pipe ports. Built for operators and OEMs that value steady torque delivery and longer drain intervals over the lower purchase price of a gerotor alternative — augers, sweepers, mixers, and conveyors running daily shifts in dust, mud, and temperature swings are its typical home.

Key Features

• Strict OEM Standard Design Manufactured in full compliance with Eaton’s original 103-1006-012 factory specifications, mounting dimensions and performance parameters, enabling direct and seamless replacement without equipment modification.

• Superior Low-Speed Stability Adopts precision gerotor cycloidal transmission structure with optimized flow distribution technology, effectively eliminating low-speed crawling and jitter for ultra-smooth rotary output.

• Compact Space-Saving Structure Features a miniaturized integrated body design with high structural rigidity, perfectly adapting to narrow installation spaces of various compact hydraulic equipment.

• Low Heat & High Efficiency Refined internal flow channel structure reduces fluid turbulence and hydraulic resistance, lowering operating temperature rise and improving overall hydraulic system efficiency.

• Enhanced Wear Resistance Core rotor and stator parts are processed with high-precision grinding technology, with excellent friction resistance, effectively prolonging continuous service life.

• Multi-Layer Leak-Proof Sealing Equipped with imported heat-resistant, oil-resistant and aging-resistant sealing kits, which effectively prevent internal pressure loss and external oil seepage under long-term operation.

• Excellent Load Adaptability Maintains stable torque output under variable load states and frequent start-stop cycles, with strong operational stability and anti-fatigue performance.

• Strong Environmental Adaptability High-strength cast iron shell resists vibration, dust, humidity and temperature changes, suitable for various outdoor and harsh working sites.

• Zero-Difficulty Maintenance Simple and reasonable internal structure reduces failure rate, realizing low daily maintenance frequency and effectively reducing later operating costs.

• Diversified Application Scenarios Widely applicable to farm machinery, road sanitation vehicles, small handling equipment and general industrial light-duty hydraulic drive systems.

Applications

• Construction Machinery：Excavators, skid steer loaders, backhoe loaders, road rollers, and compact construction equipment.
