I'm looking for a specific component for my project: a linear actuator with an 1800mm stroke that can deliver high torque at low speeds. This actuator will be mounted on a gantry system, so I'd like to ensure it fits the mounting requirements and has the necessary load capacity. Please provide details on your available options that meet these specs, including performance characteristics, dimensions, and pricing. It would be great to understand the lead times and any additional customization options you might offer. Looking forward to your prompt response!
