Danfoss H1/H1B Bent Axial Piston Variable Displacement Motor are designed primarily to be combined with other products in closed circuit systems to transfer and control hydraulic power. As part of Danfoss H1 family, these motors are designed with proven 32 degree bent axis technology, zero degree capability and higher overall efficiency, which provides a number of significant advantages. Danfoss H1B motors offers top design flexibility, whether you are looking for high sophistication or simplicity itself.

These motors come in compact size with the shortest unit length in its class, that makes them ideal for limited space installation. Built with IP67 and IP69K rated electric components and fulfilling the quality foal of 250 DPM. Additionally, Danfoss H1 Bent axis motor design leads to minimized control losses and enhanced efficiency, which have possible, due to inclusion of the smallest dead volume and flow optimized end cap as well as valve segment.

Danfoss H1B motor features optimized surface finish combined with a high spring rate and best-in-class components ensures your machine has high speed capability at a minimal angle, allowing for maximum performance. These motors comes in multiple sizes from 060, 080, 110, 160, 210 to 250, with a nominal pressure up-to 216 and maximum pressure up-to 700. Furthermore, this motor operates at high power with a balanced 450-bar delta pressure, that increases the effectiveness of your machine.
