Product details

What this servo brings to the line

The HG-SR421: Maximum radial load is 2058 N, so you can belt-drive or couple it directly without overhung-load concerns up to that limit.

Mounting and environment notes

The IP67 housing lets you install it in splash zones or particle-laden air without a purge. 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.

Frequently asked questions

What torque does the HG-SR421 deliver?

Nominal torque is 40.1 Nm, with a maximum torque of 120 Nm. That makes it suitable for high-inertia or direct-drive loads.

What is the IP rating of this servo motor?

IP67, meaning it's dust-tight and protected against temporary immersion. Good for washdown environments.
