Product Description

Known for its wide range of high-quality factory automation products, Bosch Rexroth takes great pride in its position as a market leader and respectable innovator.

The 1MR160D-A055 is one of the many high-end automation products developed by Bosch Rexroth. It functions as a rotor for 1MB frameless motors with a motor length of D and motor size of 160. This device features a typical step inference fit known as the friction-locked interference fit, which makes it possible to dismount and mount the rotor easily. In addition, the step inference fit on the Bosch Rexroth 1MR160D-A055 rotor increases rigidity and ensures the absence of tension that could interfere with the smooth running of the attached spindle.

The moment of inertia of the 1MR160D-A055 rotor is 0.0121 kgm², and it weighs 7.3 kg. Furthermore, the internal diameter of this unit is 55 mm. Its insulation classification is F, and functional ambient temperature is between 5 – 45 degrees C. The rated current of the 1MR160D-A055 rotor is 48 Amperes which aligns with its corresponding 1MB motor. It features a laminated core and a sleeve coupled with a balancing ring. The balancing rings on this rotor have tapped holes that facilitate the balancing of this unit. Before mounting this unit unto its designated, it is essential to pre-heat it to about 200 degrees C to ensure that the mounting process is achieved with ease. Once it is fitted to the spindle and cools down, it attains a final and fitting dimension. Generally, the mounting dimension A of the 1MR 160 rotors must have a minimum of 70 mm – the same applies to the 1MR160D-A055 rotor. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
