The R911252113 (1MR310B-A120) is a Bosch Rexroth rotor designed for integration with 1MB series motors, specifically matched to frame size code 310 and length code B. Engineered for use in industrial environments such as machine tools, processing centers, and transfer lines, it supports applications involving grinding, milling, and turning. The rotor operates within liquid-cooled asynchronous motor assemblies, where the coolant absorbs thermal losses from both stator and rotor. The R911252113 (1MR310B-A120) features a step interference fit and an internal diameter of 120 mm, and is intended for use in spindle units with appropriate housing, bearings, and feedback integration. Proper storage requires protection from dust, moisture, and vibration in either vertical or horizontal orientation.
