BT40 120MM Milling Spindle for High-Torque Vertical Milling Machines
The BT40 120mm Milling Spindle is a heavy-duty mechanical core engineered for industrial Vertical Milling Machines (VMC) that demand a balance of high rotational speed and extreme clamping rigidity. Featuring a standard BT-40 nose taper, this spindle ensures seamless integration with a wide range of industrial tooling for efficient material removal. The unit is designed with a precision-ground 120H6 locating diameter and a 165mm flange, providing a stable, high-accuracy mounting profile within the machine headstock. To handle the high-load demands of industrial milling, it features a specialized 4+2 bearing configuration, utilizing high-precision 7012 P4 bearings at the front and 7010 P4 bearings at the rear. With an 8000 RPM peak performance and low-maintenance grease-packed lubrication, this 410mm spindle assembly delivers the mechanical stability and rotational accuracy required for superior surface finishes in professional machining environments.
