Danfoss L/K Medium-Power Variable Axial Piston Motors is available with medium-power two-position axial piston motors, including an integral servo piston. These motors are developed for operation in closed and open circuit applications. With high-capacity bearings, a special dust seal, three clean sides for easy integration, and a wide range of displacements, Danfoss L and motors are perfect for various applications such as rollers, pavers, specialty harvesters, fan drives, and other hydrostatic solutions.

Danfoss L and K Frame motors consist of five sizes from L25, L30, L35, K38 to K45, which allow the optimum selection of hydraulic motor for the lowest possible installed cost. With a nominal pressure of 300 bar [4350 psi] and maximum pressure up to 420 bar [6090 psi], these motors are suited with various mobile applications. Based on proven technology and optimized for options, lifetime, package size, and installed cost, these pumps are suitable for agricultural and material-handling machines.

These motors are constructed with SAE-B, two-bolt, and cartridge mounting configurations, providing space constraints, ease of installation, maintenance needs, and a high level of modularity. Danfoss L and K Frame motors feature three clean sides with superior clearance and access to mounting bolts. Additionally, they have nine piston rotating groups with an 18-degree maximum angle for high efficiency and reliability using existing and proven technology.
