Heavy Duty Motor Mount Series

Quadruple angular ceramic bearings, 50,000 rpm, 0.94 hp (0.70 kW), and a rigid steel barrel for mounting make the new governed 460HD ideal for cutting or finishing harder materials.

Sealed at its front collet for wet environments. The 460’s durable, direct drive, low heat and low vibration governed motor is a reliable workhorse with powerful performance 24/7. A low vibration magnitude of 1.25 m/s² r.m.s, makes the well balanced 460HD ideal for robotic integrations. Applications include finishing, drilling, milling and routing.

Mountable area of Ø 41.15mm OD by 63.5mm.
