Product Description:

For servo drive and spindle motor systems, the Bosch Rexroth Indramat KDA 3.2-050-3-DYS-W1 is a high-performance coupling that transmits high torque precisely and effectively.

Having a torque rating of 50 Nm, this coupling is designed to connect moderate to high loads in automation, machining, and motion control networks. The coupling is made out of standard steel (W1), which is resistant and flexible and possesses relatively low moment of inertia, which is vital in dynamic servo applications because of its responsiveness. Its rotation speed can go up to 10,000 rpm, and the range of bore diameter is between 10 mm and 48 mm, which can be more flexible to different shafts with different sizes. The model is dynamically balanced (DYS), thereby reducing vibration and operating easily even at high speeds. It overcomes axial, radial, and angular misalignment; therefore, it helps to protect the connected components and increases service life. It has zero backlash, and torsion stiff, and is most suited to high precision applications and required positioning. The mounting is a clamping type of design, and ensures a secure, slip-free connection of the shaft; it does not require keyways.

With a large operating temperature range of -30°C to + 120°C, the KDA 3.2-050-3-DYS -W1 works well across many industrial settings. It does not need any lubricants and operates dry; therefore, maintenance maintenance-free over its long operational life time of more than 20,000 hours of nominal operation. It also dampens vibration moderately due to having a steel body and a flexible component inside, a moderate value of resistance, and shock absorption. This coupling is compliant with the DIN 740 standards and makes the coupling compatible with standardized mechanical interfaces.
