Short travel, 50 lbs, slow, electric linear actuator?

I need an electric linear actuator with only about 1/4 inch travel, but it must supply at least 50 lbs force. It can be real slow, and the operation is intermittant with low duty cycle. Ideally, something like a heavy-duty micrometer motorized by a stepper motor. Accuracy requirement on the linear motion is not high: about 0.003 inch. I've looked extensively on the web, and have not found a really good solution. I'd prefer to buy a complete solution with controller.
