Received Linear rails / ball screws

I received the linear rails and ball screws from Joomen yesterday.  Packaging was neat and they used a plywood to ensure screws don’t get bent during transport.  I received 8 SUU20 blocks instead of 4 Ballnut blocks.  I didn’t plan to use the ballnut blocks anyway so no big deal.

Initial review of screws shows that the overall quality is acceptable.  The ball nut on the 350mm screw was a bit tight to turn.   Most carriages on the 20mm rails are not so smooth,  I’ll look at adjusting them later (hopefully they can be adjusted).  Delivery and service from Joomen was fast and I’m quite happy except for the previously mentionned issues.  I also received my screws order from McMaster.
