Zero Backlash Universal Joints
(OP)
I'm looking to incorporate a small (12-15mm OD) u-joint with little or no backlash. It would need to operate at >=20 degrees around 10RPM. In my industry, we manufacture almost everything unless it's made by an approved vendor, which is an exhausting process. I've found the attached u-joint, but can't figure out how it's made or how to design something similar. Any thoughts on alternative designs or how these are made?

@Swall - I'm actually more concerned with translation in the u-joint than rotational backlash.

For low torque I wonder how a piece of rubber hose would work.

I.e., if I am understanding your loading case correctly, you will be better off developing a custom solution from scratch than copying someone else's design that you do not understand.

I have had good luck with Flexible drive shafts similar to this.
