DYFJM-180(110)20/11A2-F Low-Runout Grinding Spindle

This 180 mm spindle prioritizes geometric control through a 110 mm journal and radial and axial runout limited to 0.0005 mm. Its 300 N/μm radial stiffness supports cylindrical grinding where shaft stability matters more than maximum rotational speed.
Diameter Φ180mm
Maximum speed 2000rpm
