What coupler? I just see some blocks and chunks of metal and a a man getting acquainted with them. Please have some close-ups and clarity of what those of metals look like.
There are a few problems here: Terminology -- the "split" coupling is a helical or beam coupling. We have enough names for it, we don't need yet another. Oldham couplings don't have "spiders" -- jaw couplings have spiders. Misumi calls them "spacers", not spiders. Other companies call them midsections. And then there are fundamental mistakes here: You're not measuring "flexibility" with your device, you're measuring torsional stiffness. And you're doing it poorly -- of course the Oldham coupling will deflect angularly, if, as you state, you torque it way beyond its rating. And no, no standard Oldham coupling (as shown, with a rectangular tenon) would be rated for "4 or 5 degrees" of angular misalignment -- even the very sloppy, soft, molded midsection Misumi Oldham coupling. There's no discussion here of homokinetic motion, for a ball screw application; no mention of reactive forces (which will be very high for a disc coupling if there's any radial misalignment); come to think of it, no mention of radial misalignment. Other than that, this is a great selection guide.
Do you also have couplings for Allen Bradley servo motors (type: MPL-B310P-MJ72AA). Motor has a keyway shaft (16 MM dia.), keyway slot is 5x5x25 MM. The other end of the coupling I require for a 10 MM dia shaft (no keyway)
I can't believe I watched all of this. I heard misumi has good products but when I tried to chat with a "engineer" from their site to find a linear guide rail and carriage with similar specs or exact alternatives to what everyone in 3d printing refers to as mgn12c and mgn12h made by Hiwin or similar companies. The tech was the absolute rudest person and treated me like I was dumb. While I am not knowledgeable in their products I am far from dumb and found it very disrespectful for someone representing this company to act like this. Even after I explained to him he still literally offered no help at all. I even sent a link to a mgn12 spec sheet and said I think their versions are THK? Anyway, this is the second time I have been disappointed. Maybe someone can point me in the right direction to a company that cares about their customers and provides a source for superior products.
Links to the parts showcased in the video would be great. I have been looking for a good actuator/coupler/motor combo for a CNC project, but sadly after watching the video I am still at a loss of what part numbers I should be looking for.

Nilesh Mistry, At the bottom of the video below the time tracker near the right hand side is an icon that says "CC". If you click this, this is where to turn your CC On or Off. Thanks for watching!

Thank you very much for the details. is anyone watching this video in 2021. after 7 years still invaluable video🖤
Glad you enjoyed it!
nice top model chef

Terrible video with no zoom into those walnuts or almonds on the table.

Steven Elliott, thanks for watching! We appreciate your detailed comments, and hope you watch our other series.
what type of coupling is best for a Detroit series 60 11.1 engine?
For direct drive or couple spindles ( Say Milling Spindle) which type of coupling is used ??

Just buy them from THK directly. SRS12 is the rail and C or LC (h) is the block.
hear hear ,that is one company to stay away from. it's -*

CC covers up the parts on the table.....

you never discuss rpm. high rpm along with even little misalignment cause rapid wear.
Are you serious??? All you have shown is a big man playing with some small things? Disgrace video for Misumi.
