The Getting Started manual for the UR44 has technical specs but it doesn’t seem to be available as a download.

Here’s a few details for you all.

The manual contained some errors in the specs. I have updated them from an Errata document and highlighted them in red below. I have left the incorrect values and placed them inside { } brackets.
