1MR310D-A118/S026

The Bosch Rexroth Indramat 1MR310D-A118/S026 from the 1MB High-Speed Asynchronous Motors series delivers precision rotor performance with a motor size of 310 and a motor length D that integrates seamlessly into high-speed spindle assemblies. Featuring a Rotor Design with Step Interference Fit, this rotor model ensures easy mounting and dismounting while maintaining exceptional concentricity. The inner diameter of 118 mm accommodates direct-drive motor spindles and supports heavy-duty machining applications. Designed by Bosch Rexroth Indramat, this frameless spindle rotor embodies the company’s reputation for robust, high-speed motion control components.

Engineered for stability, the 1MR310D-A118/S026 weighs in at 80 kg and exhibits a moment of inertia of 0.492 kg·m², balancing rotational mass with dynamic responsiveness. An air gap between rotor and stator channels heat to the stator where a liquid cooling system dissipates thermal energy efficiently. The design adheres to protection class IP00 per IEC 60529, necessitating protective covers in humid or damp environments to maintain optimal performance. Operating reliably within an ambient temperature range of 0 °C to 40 °C, this rotor upholds rigidity and thermal stability during extended cycles.

Ideal for integration into processing centers, machine tools, transfer lines, and specialized production machinery, the 1MR310D-A118/S026 enhances spindle drive rigidity and running smoothness. Its precise interference-fit construction reduces vibration and extends bearing life under high-speed conditions. Backed by global shipping and a one-year warranty, this rotor model ensures dependable uptime and simplified maintenance in demanding industrial environments.
