Cross sectional dimensions for CAD drawings

**Husky** · 24-02-2013

Hey guys, hoping you can help me here. I've been looking to start CAD'ing up the parts I think I will require in my build so I can then fiddle about with them in a nice assembly. Trouble is, I can't seem to find the dimensions of the first part I'm looking at doing

. It's the runners here: fl15ca-z0 either FL15CA or FL20CA would be good to get me started. Orrrrr, am I looking at the wrong type of runner and there is a really common one everybody uses that I've missed?

I did try the search button but couldn't see anything for those part numbers.

Cheers!

Are the dimensions further down on the zapp page you linked to no good?

FL15; 47W, 56.2L, 24H
FL20; 60, 70.5, 30 (mm)

Ah, so a FL15CA is the same as a CB?

Oh dear I've been staring at it all along

:-)

Looks like the only difference with CA / CB is top or bottom fix (mounting?).

CA, CB specifies if the blocks have flanges, so can be mounted from both sides, or no flanges in which case you're limited to one side. Also you can get bearings like those cheaper on Aliexpress, among other places.
