The R911251742 (1MR242N-A071) is a motor rotor designed for Rexroth Indramat 1MB synchronous spindle motors. This rotor, with a motor size of 242 and length N, employs a step interference fit and is finished for installation. It is constructed from wear-resistant steel and includes grease-lubricated ball bearings to reduce frictional heat. The rotor supports maximum speeds of up to 16,000 rpm and possesses a rotor inertia of 0.135 kg·m². Its design permits it to withstand high radial loads, making it suitable for applications involving belt pinions and pulleys within a 0 to 40 °C operating temperature range.
