They are very much sized to suit a standard Bridgeport mill and the Warco looks similar. Align seems to be the 'brand name' (https://www.align.com.tw/index.php/other-en/powerfeed/). So for specific info. on your question, have a sniff around for 'Bridgeport Y-axis power feed' to see how the X- and Y- might differ. I thought Warco themselves offered powerfeeds so you might get some info. from their site on any differences. Also look at Grizzly in the US as the mill will be a generic far-East version. GT Precision might have some info. (https://www.gtmachineparts.co.uk/bridgeport-parts/6f-power-feed). I think you can ring them up and pick their brains.
