Storage range is -15 to +70 °C—fine for warehouse stocking. Make sure the radial load stays under the 2058 N spec, especially for belt or pulley drives; an overhung load above that can shorten bearing life.","metaTitle":"HG-SR421 AC Servo Motor, 40.1 Nm, IP67","metaDescription":"HG-SR421 AC servo motor with 40.1 Nm nominal torque, 4.2 kW, IP67.
