Rugid cast iron gear motors
With displacements from 17.6 cm3 to 48.3 cm3 [1.08 in3 to 2.95 in3] and pressure ratings up to 276 bar [4,000 psi], our cast iron gear motors maximize mobile application performance at peak power levels and operating temperatures. They reduce emissions and increase productivity and fuel efficiency while providing installation flexibility in tight spaces thanks to side and rear port options and a package size 20% smaller than that of conventional gear motors.
Features and benefits
- Cast iron construction provides high strength.
- Custom-engineered shaft bearings and dual pressure-balanced thrust plates optimize internal bearing lubrication, allowing for high starting torque and long life with fluid viscosities as low as 8 mm²/sec [52 SUS].
- Compact three-piece design with bearings located in the front flange and rear cover minimizes overall package length and increases radial load carrying capability.
- Variety of integrated valve options make this motor well suited for high-performance fan drive applications.
- Pressure-balanced thrust plates provide improved efficiency at extreme pressures and temperatures.
- High-temperature Viton® seals are well suited for today’s hotter running machines.
- Three-piece ductile iron construction provides increased durability and power density, with reduced adverse efficiency effects at high temperatures.
Applications
- Turf care
- Construction
- Where high power density and maximum performance under high pressure are required
