MAG18

Kayaba MAG18 — travel motor 18 cm³

Kayaba MAG18 axial piston travel motors are designed for open circuit hydraulic systems as a final drive for crawler equipment. The design combines an axial piston swashplate motor with a cartridge-type planetary gearbox (case-rotation). The built-in two-speed mechanism provides automatic or manual switching between low-speed/high-torque and high-speed/low-torque modes depending on load. Used as a travel motor (final drive) in mini excavators up to 4 tonnes from Hitachi, Volvo, Yanmar, Takeuchi and Sunward.

Full model range in the section Kayaba MAG-MSF series.
