Heavy Duty Motor Mount Series

Ceramic bearings, an ER 11 collet, and a rigid steel barrel for mounting make the 450HD ideal for cutting or finishing harder materials. Sealed at front collet for wet environments. Our durable direct-drive governed motor makes this unit a reliable workhorse. Powerful 24/7 performance with 0.88 hp (0.66 kW) at governed 40,000 rpm. Very low vibration magnitude of 1.25 m/s² r.m.s, makes the well-balanced 450HD ideal for robotic integrations. Applications include finishing, drilling, milling, and routing.

Mountable area of Ø 41.15mm OD by 63.5mm. Ceramic and angular contact bearing options available.
