Any hole or opening that is going to go through a seal should have the edges chamfered. If you can't do that put a small piece of tape over the hole to protect the seal, then remove it when it's through.
Excellent point. I chamfer the edge of the grease hole with a fine stone and electrical tape around it is a good idea. Let a long tail of tape and pull it free after the seal lip has passed beyond the hole.
The fact that the bearings slide onto the spindle so easily would be the lack of interference the PDF lists. Like most parts on manufactured goodies these days, they don't require much alignment or coaxing to assemble. Too much clearance IMO. The difference between a thousandth or two can change everything. Problem is, they don't want them too tight of they'd be a bear to remove all the time. As long as your preload is near perfect zero you shouldn't have an issued. Just make sure it's as clean as possible inside there. One decent sized piece of dirt and the rollers can stop rolling, then the inner bearing race will start to spin and lunch a spindle. That's ugly.
