Product Description:

The Bosch Rexroth Indramat KDA 2.1-150-3-DYS-W1 is an industrial-grade precision hydraulic unit applicable in the KDA spindle drive system.

It is precise and is used in hydraulic applications having a displacement of 2.1 cm³/turn. It is capable of working at a high pressure of 150 bar, maintains a consistent torque, and has precise regulation of hydraulic motion within such a challenging system. This model boasts three parts, which enable one to have multi-use in a small space. It is made of W1 grade, which is usually an alloy of aluminum or a composite that will not corrode easily, so both strength and durability to the unfavorable operating environment. The unit can be mounted on a flange, and its installation is secure and stable inside machinery systems or enclosures. The sizes of the ports are also standard, typically G 1/2 or SAE equivalents, though this varies with the particular suppression method and regional requirements. The KDA 2.1-150-3-DYS-W1 is bi-directional rotational, and each section can be customized to be in either direction, permitting use in a broad range of system formations.

It runs as fast as 3000 rpm and employs conventional sealing systems in terms of mineral oil-based hydraulic fluids. The shaft seal is designed to support up to 10 bar of pressure, which assures the seal of containment at high loads. Digital features are provided through a 16-bit speed command interface, which is a parallel data port that is equivalent to a +/-10V analog signal, which makes the drive a high-resolution, responsive drive. The normal temperature range of functioning is between -20°C and 80°C, and so it fits in both ordinary and reasonably extreme manufacturing environments. This hydraulic drive element weighs around 7-10 kg, depending upon the configuration, and is compact, rugged, and precise in implementation of digital controls.
