This standard model does not include an oil seal; order the HG-KR_J variant for that. It's rated for 2.4 N·m continuous torque and hits 8.4 N·m peak, spins 3000 rpm rated, 6000 rpm max, and handles loads up to 17 times the rotor inertia without complaint. The 22-bit absolute encoder tells the drive exactly where the shaft is on power-up – no homing needed on a typical machine. Install indoors at ≤2000 m elevation and 0–40 °C non-condensing; vibration resistance is 49 m/s² on X/Y axes. Compatible servo amplifiers support CC-Link IE, SSCNET/H, or general-purpose interface.","metaTitle":"Mitsubishi HG-KR73 Servo Motor, 0.75 kW, 3000 rpm, 22-bit En","metaDescription":"MELSERVO-J4 series servo motor, 2.4 Nm rated, 8.4 Nm peak, IP65, 22-bit absolute encoder.
