Eaton® Char-Lynn® Low Speed High Torque Orbit Motor for Swing Drive October 20144
General Introduction
Features
• Low speed high torque Char-Lynn® motor for Swing• Direct drive (no reduction gear)• Displacement from 165 cm3/rev to 490 cm3/rev, maximum
pressure up to 19.6 MPa• Optionally integrate mechanical parking brake, time delay
valve and shock less relief valve
Benefits
• Maintenance cost saving cause no reduction gear oil required
• Cost competitive due to simple structure design• Reduced energy consuming attributed to higher
mechanical and volumetric efficiency• Less mechanical shocks by smooth and precise control• Proven performance by 30+ years experience
Typical mini excavator weight (ton)
Recommendation fluids: ISO VG32, 46, 56, 68 mineral oilRecommended system operation temperature: - 30˚C to 80˚CRecommended oil viscosity: 24 to 50 cStRecommended cleanliness: ISO 18/13
Typical application
• Mini excavator• Excavator attachment• General swing application
